Understanding Samsung TV USB Ports: Types, Standards & Fundamentals
Before diving into specific features, understanding what type of USB technology your Samsung TV uses helps set realistic expectations for transfer speeds and power delivery.
USB Standards on Samsung TVs
Most Samsung televisions - regardless of price tier - feature USB Type-A ports operating on the USB 2.0 standard. This means theoretical maximum transfer speeds of 480 Mbit/s, though real-world performance typically falls below this ceiling. USB 3.0 ports occasionally appear on premium models, but USB 2.0 remains the standard across most lineups even in 2026.
The distinction between USB 2.0 and USB 3.0 matters less for media playback than you might think. Both standards handle video streaming from connected drives without stuttering, since bitrates for most video content remain well within USB 2.0's capabilities.
Port Labeling Explained
Samsung uses specific labels to differentiate USB port capabilities:
Port Label | Power Output | Best Used For |
|---|---|---|
USB (5V 0.5A) | 2.5 watts | Flash drives, keyboards, mice |
USB (HDD 5V 1A) | 5 watts | External hard drives, streaming sticks |
USB | Standard power | General USB devices |
SmartThings USB | Varies | Originally for SmartThings dongle, functions as regular USB |
The HDD-labeled port provides double the amperage of standard ports - critical for devices that draw more power during operation. If you're experiencing issues with external hard drives not being recognized, connecting to the wrong port type is often the culprit.
Mass Storage Class (MSC) Requirement
Samsung TVs support only Mass Storage Class (MSC) USB devices. This technical term simply means the TV communicates with USB drives as storage devices rather than complex peripherals. Standard flash drives and external hard drives qualify as MSC devices.
What doesn't work: USB hubs, multi-card readers with complex controllers, and drives with built-in encryption hardware that requires driver installation. The TV cannot recognize these devices regardless of which port you use. If you're looking to perform a Samsung TV firmware update, you'll need a standard MSC-compatible drive.
Where to Find USB Ports on Your Samsung TV: Complete Location Guide by Model
Locating USB ports varies significantly between Samsung TV series. Premium models use external connection boxes, while standard sets integrate ports directly into the back panel.
QLED Series (Q60-Q90)
Standard QLED televisions position USB ports on the back panel, typically grouped in the lower-right section when viewed from behind. Most QLED models include two USB ports - one standard 5V 0.5A port and one HDD 5V 1A port for higher-power devices.
The exact layout depends on screen size. Smaller QLEDs (43-55 inches) often feature a side-facing port arrangement that's easier to access after wall mounting. Larger models (65+ inches) generally position all ports facing straight back.
Neo QLED and One Connect Box Models
Premium Neo QLED televisions use an external One Connect Box that houses all connection ports. This design keeps the TV panel incredibly thin and makes cable management significantly cleaner - especially important for wall-mounted installations.
The One Connect Box typically includes two to three USB ports. Look for them alongside HDMI ports on the box itself, not on the television. A single slim cable connects the One Connect Box to the TV, so you can position the box wherever convenient - inside a cabinet, behind furniture, or mounted behind the TV.
Crystal UHD Series
Samsung's Crystal UHD lineup positions USB ports on the back panel, similar to standard QLED sets. These budget-friendly 4K televisions usually include two USB ports, though some smaller screen sizes may have only one.
On larger Crystal UHD models (55+ inches), ports typically face straight back. Smaller models sometimes angle ports to the side for easier access. Check your specific model's diagram in the user manual for exact positioning. During setting up new Samsung TV process, the included documentation shows port locations specific to your model.
The Frame TV
The Frame TV's unique aesthetic design influences port placement. Standard Frame models include ports on the back panel behind a slim cover that maintains the clean, picture-frame appearance.
Higher-end Frame installations may include a One Connect Mini box, which moves ports to an external unit similar to premium Neo QLED models. This keeps all cables away from the thin frame profile.
Finding Your Specific Model's Ports
If you're still uncertain about port locations for your exact model, the best resource is the printed quick-start guide included with your TV or the digital user manual available on Samsung's support website. Enter your model number (found on a sticker on the back of the TV or under Settings > Support > About This TV) to access model-specific diagrams.
During initial Samsung TV setup, the quick-start guide specifically identifies port locations and recommended connections for your model.
Samsung TV USB Port Power Specifications: 5V 0.5A vs 5V 1A Explained
Understanding power output differences prevents frustration when connecting devices that refuse to work properly.
Standard USB Port (5V 0.5A)
The standard USB port outputs 2.5 watts of power - calculated by multiplying 5 volts by 0.5 amps. This provides sufficient power for:
USB flash drives (all sizes)
Low-power external SSDs
USB keyboards and mice
Most webcams
These devices draw minimal power and work reliably in either port type. If your flash drive functions normally on a computer, it will work in the standard port.
HDD USB Port (5V 1A)
The HDD-designated port doubles power output to 5 watts (5V × 1A). Samsung designed this port specifically for external hard drives that lack their own power supply. Desktop external drives typically require wall power regardless, but portable 2.5-inch drives often function solely on USB power - provided that power meets minimum requirements.
Devices that benefit from the higher-power port include:
Portable external hard drives without external power
Amazon Fire TV Stick (prevents "underpowered" warnings)
Google Chromecast devices
Other streaming sticks
If you're powering a Fire Stick through your TV's USB and experiencing issues, check our guide on Firestick not working Samsung TV for power-related troubleshooting.
Power Requirements by Device Type
Device | Typical Power Draw | Recommended Port |
|---|---|---|
USB Flash Drive | 0.5-1.5W | Either |
Portable SSD | 1-2W | Either |
Portable HDD (2.5") | 2.5-4.5W | HDD (5V 1A) |
Amazon Fire Stick | 2-3W | HDD (5V 1A) |
Chromecast | 2-3W | HDD (5V 1A) |
USB Keyboard | 0.1-0.5W | Either |
USB LED Strips | 2-5W+ | Caution advised |
A Warning About LED Bias Lighting
Many users connect USB-powered LED strips to their TVs for ambient backlighting. While these often work initially, high-power LED strips can stress the TV's internal power delivery over time. Reports in Samsung community forums describe power board failures after extended LED strip use.
If you want bias lighting, consider powering LED strips from an external USB adapter rather than the TV's ports. This keeps sustained power draw off the TV's internal components entirely.
Samsung TV USB Format Guide: FAT32, exFAT, and NTFS Compatibility
File system compatibility is the most common cause of USB recognition failures. Different Samsung TV types support different formats.
QLED, SUHD, and Neo QLED TVs
Premium Samsung televisions support all three major file systems:
FAT (FAT12/FAT16)
exFAT
NTFS
For these TVs, exFAT represents the best choice for most users. It handles large files without the 4GB limitation of FAT32 and works natively on both Windows and Mac computers.
Full HD and Budget TVs
Lower-tier Samsung TVs have more restrictive file system support:
FAT16
FAT32
NTFS (read-only)
The "read-only" NTFS support means Full HD TVs can play media from NTFS drives but cannot write to them - relevant for recording features.
The FAT32 4GB File Size Limitation
FAT32 cannot store individual files larger than 4GB. This limitation creates problems for high-bitrate video files, which frequently exceed this threshold. A single episode of a 4K HDR show might run 5-8GB, making FAT32 impractical.
Recommendation by TV Type:
TV Type | Best File System | Reason |
|---|---|---|
QLED/Neo QLED | exFAT | Large file support, universal compatibility |
Crystal UHD | exFAT | Large file support |
Full HD | FAT32 or NTFS | FAT32 for recording capability, NTFS for large files |
File and Folder Limits
Samsung TVs impose limits on the number of files and folders they can index:
QLED and SUHD TVs: Maximum 8,000 files and folders, up to 1,000 per individual folder
Full HD TVs: Maximum 4,000 files and folders
Exceeding these limits causes some files to become invisible to the TV, even if the drive is otherwise recognized. If your TV sees the drive but reports "No Content Found," check whether your drive contains too many files.
How to Format a USB Drive
On Windows:
Connect your USB drive to your computer
Open File Explorer and right-click on the drive
Select "Format"
Choose your file system (exFAT recommended for QLED/UHD TVs)
Click "Start" and wait for completion
On Mac:
Open Disk Utility (Applications > Utilities)
Select your USB drive from the left sidebar
Click "Erase"
Choose "ExFAT" for the format
Click "Erase" to confirm
If you encounter format recognition errors after connecting to your TV, consulting our broader Samsung TV troubleshooting resource may help identify other contributing factors.
Samsung TV USB Video Format Compatibility: Complete Codec Guide 2026
Understanding the difference between container formats and codecs prevents most playback failures. The file extension (.mp4, .mkv) tells you the container, but the codec inside determines compatibility.
Supported Container Formats
Samsung TVs recognize these video containers:
MP4 (most compatible)
MKV (versatile, supports multiple audio tracks)
AVI (older format, limited codec support)
MOV (Apple format)
WebM (web-optimized)
TS (Transport Stream, used in broadcasts)
3GP (mobile format)
VOB (DVD format)
ASF (streaming format)
Supported Video Codecs
The codec inside the container matters more than the container itself:
Video Codec | Support Level | Notes |
|---|---|---|
H.264/AVC | Full support | Most compatible option |
HEVC/H.265 | MKV/MP4/TS only | Premium format for 4K content |
VP8 | Full support | Google's web codec |
VP9 | Full support | Used by YouTube |
MPEG-4 | Full support | Older standard |
MPEG-2 | Full support | DVD/broadcast standard |
WMV/VC-1 | Deprecated | Not supported on 2025+ basic models |
Critical: DTS Audio Codec Not Supported (2022+ TVs)
Here's something that frustrates countless users: Samsung removed DTS audio codec support starting with 2022 model year televisions. This change persists through 2025 and 2026 models.
If your MKV or MP4 file has video but no audio, DTS is almost certainly the cause. Many movie files - especially those from Blu-ray rips - default to DTS audio tracks.
Solutions:
Choose an alternative audio track if your file contains multiple tracks (AAC or Dolby Digital)
Convert the audio track from DTS to AAC using video conversion software
Look for file versions specifically encoded with AAC audio
This DTS limitation catches experienced users off guard because older Samsung TVs played these files perfectly. If audio issues persist, our guide on Samsung TV audio out of sync addresses related playback problems.
Resolution and Frame Rate Limits
Samsung TVs support impressive specifications for USB playback:
H.264: Up to 4K@60fps
HEVC: Up to 4K@120fps on premium models, 4K@60fps on standard models
8K HEVC: Supported on 8K TVs only
Files exceeding these limits may stutter, drop frames, or refuse to play entirely. If you're experiencing choppy playback on files that worked elsewhere, the bitrate or frame rate likely exceeds your TV's capabilities.
For optimal video quality when playing content from USB, you may want to adjust your Samsung TV picture settings to match the source content's characteristics.
Codec Compatibility Quick Reference
For maximum compatibility, encode videos as:
Container: MP4
Video Codec: H.264
Audio Codec: AAC
Resolution: 1080p or 4K (match your TV's resolution)
This combination works on every Samsung TV with USB playback capability, eliminating codec-related playback failures entirely.
Samsung TV USB Audio Format Support: MP3, AAC, FLAC & More
For users with music libraries, Samsung TVs function as surprisingly capable audio players.
Supported Audio-Only Formats
Format | Support | Notes |
|---|---|---|
MP3 | Full | Universal compatibility |
AAC | Full | Preferred streaming codec |
FLAC | Full (QLED/SUHD) | Lossless audio |
WAV | Full | Uncompressed audio |
OGG | Full | Open-source format |
ALAC | Full (QLED/SUHD) | Apple lossless |
WMA | Limited | Not supported on newer basic models |
Audio Codecs Within Video Files
Video files can contain various audio codecs. Samsung TVs support these audio codecs within video containers:
Dolby Digital (AC3): Up to 5.1 channels
Dolby Digital Plus (DD+): Up to 5.1 channels
AAC: Primary recommended codec
MP3: Wide compatibility
Vorbis: 5.1 channel support
LPCM/PCM: Uncompressed audio
Not Supported: DTS, DTS-HD, TrueHD (on most consumer models)
Sample Rate Support
Supported sample rates vary by codec but generally include: 8, 11.025, 12, 16, 22.05, 24, 32, 44.1, and 48 kHz. CD-quality audio (44.1 kHz) and standard video audio (48 kHz) work without issues.
For optimal audio playback from USB, access your Samsung TV sound settings to configure output options and audio modes appropriate for your connected speakers or soundbar.
How to Play Media from USB on Samsung TV: Step-by-Step Guide

Samsung TV USB Recording & PVR: Complete Setup Guide for Timeshift
Samsung's built-in PVR (Personal Video Recorder) feature turns your TV into a DVR without additional hardware - but it comes with significant limitations and regional restrictions.
Understanding PVR Capabilities
The PVR feature allows you to:
Record live broadcasts to a connected USB drive
Schedule recordings in advance for specific programs
Pause and rewind live TV using Timeshift
Watch recordings directly from your TV
Critical Regional Restrictions
PVR and Timeshift features are disabled in the United States, Canada, and several other regions. Samsung implements these restrictions at the firmware level, and they cannot be bypassed through normal settings.
Countries with confirmed PVR functionality include most of Europe (with some exceptions like Italy and certain Eastern European nations), Australia, and various Asian markets. If you're in a restricted region, the recording options simply don't appear in your TV's menu.
USB Drive Requirements for Recording
Recording demands more from USB drives than simple playback:
Minimum capacity: 256GB recommended
Speed: USB 2.0 or higher, 5,400 RPM for HDDs
Connection: Must use the 5V 1A (HDD) port
Format: TV will format the drive for exclusive recording use
Important: When you format a drive for recording use, it becomes dedicated to that TV. You cannot play the recordings on a different TV or copy them to your computer - the recordings are encrypted to prevent piracy.
How to Record Live TV
Instant Recording:
Tune to the live broadcast channel you want to record
Press the 123 button on your Samsung Smart Remote
Scroll past the number pad to find the Record option
Select Record - recording begins immediately
Scheduled Recording:
Press Home and select Live TV
Access the Guide or Schedule Manager
Navigate to the program you want to record
Select the program and choose Schedule Recording
Confirm the recording time and date
For navigating the program guide efficiently, our Samsung channel guides explanation covers guide features and navigation shortcuts that make scheduling recordings easier.
Using Timeshift
Timeshift allows you to pause live TV and resume where you left off - like having a personal buffer for live broadcasts:
While watching live TV, press the 123 button
Select Timeshift from the options
The TV begins buffering content to your USB drive
Use Pause, Rewind, and Fast Forward controls as needed
Press Stop or change channels to end Timeshift
Timeshift buffers up to 90 minutes depending on your drive and TV model. This buffer is temporary and cannot be saved as a permanent recording.
Limitations to Know
Streaming apps cannot be recorded: Netflix, Prime Video, Samsung TV Plus, and all streaming services block recording due to DRM protection
Only broadcast content: Recording works with over-the-air antenna, cable, and satellite signals
Drive exclusivity: A formatted recording drive cannot be used for general storage simultaneously
For dedicated recording functionality, our detailed guide on how to record to USB Samsung Smart TV provides additional recording tips and troubleshooting.
Connecting Peripherals to Samsung TV USB: Keyboards, Mice & More
USB ports on Samsung TVs accept more than just storage devices. Various peripherals enhance the Smart TV experience.
USB Keyboard Setup
Connecting a USB keyboard dramatically improves text input for web browsing, app logins, and search functions:
Plug the USB keyboard into any USB port
Wait a few seconds for automatic detection
Begin typing - no additional setup required
Most USB keyboards work immediately without driver installation. Wireless keyboards with USB dongles also function, though Bluetooth keyboards require different pairing methods.
Keyboard shortcuts vary by app, but standard keys work for text input throughout Tizen OS.
USB Mouse Setup
USB mice provide point-and-click navigation similar to using a computer:
Connect the USB mouse to any USB port
A cursor appears on screen within seconds
Click to select, scroll to navigate lists
Limitation: Not all apps support mouse input. Native Samsung apps and the web browser work well with mice, but some third-party streaming apps ignore mouse input entirely.
Webcam Connectivity
Select Samsung TV models support USB webcams for video calling applications. Compatibility depends on both your TV model and the specific webcam - Samsung doesn't publish a comprehensive compatibility list.
Generally, UVC (USB Video Class) compliant webcams have the best chance of working. Popular models from Logitech often function correctly on supported TVs.
Streaming Device Power
Fire TV Stick, Chromecast, and similar streaming sticks can draw power from your TV's USB port instead of wall outlets. This creates cleaner cable management, especially for wall-mounted TVs.
Best practices:
Use the 5V 1A (HDD) port for streaming sticks
If you see "underpowered" warnings, the TV's USB cannot meet the device's needs
Consider wall power if performance seems unstable
If your streaming stick experiences issues when powered by the TV, our guide on Fire Stick Samsung compatibility covers power-related troubleshooting in detail.
USB Hub Limitations
Samsung TVs generally do not support USB hubs. Connecting a hub rarely works - the TV typically ignores all devices connected through the hub. Connect peripherals directly to the TV's built-in USB ports.
If you need more USB connections than your TV provides, prioritize which devices you connect based on usage frequency. Storage devices and streaming sticks typically take priority over keyboards, which you might connect only when needed.
External Audio Devices
While USB audio interfaces aren't supported for output, you can connect Sonos to Samsung TV or connect soundbar Samsung TV using optical or HDMI ARC connections for better audio quality than the TV's built-in speakers.
How to Update Samsung TV Firmware via USB: Complete Tutorial
When internet updates fail or you need a specific firmware version, USB updates provide a reliable alternative.
When to Use USB Updates
USB firmware updates make sense when:
Your TV lacks internet connectivity
Over-the-air updates repeatedly fail
You need to install a specific firmware version
Network-based updates timeout or freeze
Step 1: Find Your TV Model Number
Before downloading anything, identify your exact model number:
Press Home on your remote
Navigate to Settings > Support > About This TV

Extract/unzip the downloaded firmware file on your computer
Copy all extracted files to the root directory of the USB drive (not inside any folders)
Safely eject the USB drive from your computer
The files must sit directly on the USB drive, not within subfolders. Placing them inside a folder causes the TV to report "no update found."
Step 4: Install the Update
Insert the prepared USB drive into your TV's USB port
Navigate to Settings > Support > Software Update
Select Update Now
The TV scans the USB drive and finds the update
Confirm when prompted to begin installation
Critical warnings:
Do NOT turn off the TV during the update
Do NOT remove the USB drive during the update
The TV will restart automatically when complete
Troubleshooting Failed USB Updates
Problem | Solution |
|---|---|
"No update file found" | Verify files are in root directory, not in a folder |
Update file not recognized | Reformat USB to FAT32, redownload firmware |
Update freezes | Try different USB drive, different USB port |
TV won't boot after update | Wait 10 minutes; contact Samsung if unresponsive |
If your TV becomes unresponsive during or after an update, checking for a Samsung TV frozen condition and following recovery steps may help.
For general firmware management, our Samsung TV firmware update guide covers both network and USB update methods with additional troubleshooting steps.
Samsung TV USB Not Working? Complete Troubleshooting Guide
When USB devices refuse to cooperate, systematic troubleshooting identifies the cause faster than random attempts.
Quick Diagnostic Checklist
Before diving into complex solutions, verify these basics:
[ ] USB device works normally when connected to a computer
[ ] USB drive contains files in supported formats
[ ] Drive is formatted in a compatible file system
[ ] Total file count is under the TV's limit (4,000 or 8,000)
[ ] USB is connected directly (not through a hub or extension cable)
Solution 1: Try a Different USB Port
Samsung TVs include multiple USB ports with different power capabilities. If one port doesn't work:
Remove the USB device
Connect it to a different USB port
Wait 10-15 seconds for detection
Check the Source menu for the device
The 5V 1A (HDD) port often provides better compatibility for devices that don't work in standard ports.
Solution 2: Format the USB Drive
Incorrect file system formatting causes most recognition failures:
Connect the USB drive to a computer
Back up any important data
Format the drive to exFAT (QLED/UHD TVs) or FAT32 (Full HD TVs)
Copy your media files back to the drive
Reconnect to the TV
Solution 3: Power Cycle the TV
A full power cycle clears temporary glitches:
Turn off the TV using the remote
Unplug the TV from the wall outlet
Wait at least 30 seconds (60 seconds is better)
Plug the TV back in
Turn on and test USB connectivity
This process resets the TV's USB detection system and often resolves unexplained failures. If your TV seems to unfreeze Samsung TV screen after this reset, the issue was likely a temporary software glitch.
Solution 4: Reset Smart Hub
If USB worked previously but stopped:
Go to Settings > Support > Self Diagnosis
Select Reset Smart Hub
Enter PIN when prompted (default: 0000)
Wait for the reset to complete
Test USB connectivity again
To properly clear cache on Samsung TV, Smart Hub reset often resolves issues that simple restarts don't fix.
Solution 5: Check File System and File Count
If the TV sees the drive but shows "No Content Found":
Connect the drive to a computer
Count total files and folders
Ensure count is under 4,000 (Full HD) or 8,000 (QLED)
Remove excess files if necessary
Verify file formats are supported
Solution 6: Remove Extension Cables
USB extension cables frequently cause recognition problems. The additional connection points and cable length can cause signal degradation or insufficient power delivery.
Always connect USB devices directly to the TV's built-in ports. If cable length is an issue, consider repositioning the TV's One Connect Box (if applicable) or using a USB drive with a longer built-in connector.
Solution 7: Disconnect Other USB Devices
Multiple USB devices connected simultaneously can overwhelm the TV's USB controller. Disconnect all USB devices except the one you're troubleshooting.
Solution 8: Factory Reset (Last Resort)
If nothing else works, a factory reset returns all settings to defaults:
Go to Settings > General > Reset
Enter PIN (default: 0000)
Confirm the reset
Set up your TV again from scratch
Test USB connectivity
Warning: Factory reset erases all settings, app logins, and customizations. Use this only after other solutions fail.
When Hardware Repair is Needed
If USB ports provide no power (connected devices don't light up) across all ports and after all troubleshooting, the USB controller or power delivery hardware may have failed. This requires professional repair or potential replacement.
For recurring freezing issues related to USB devices, Samsung TV keeps freezing provides additional diagnostic steps. If your TV experiences boot loops or restarts, the Samsung TV keeps rebooting guide addresses those specific symptoms. Sometimes these issues relate to overall system performance, so checking if your Samsung TV so slow has general performance problems may reveal underlying causes.
USB Always Powered in Standby Mode
Many users notice USB ports remain powered even when the TV is "off" in standby mode. This is intentional behavior in Tizen OS - the ports stay active to support features like quick start and to maintain power for streaming devices.
There is no setting to disable this behavior. If you need to completely cut power (for example, to reset an attached streaming device or to fix a Samsung TV not responding situation), you must either:
Unplug the TV from the wall outlet
Use a smart power strip that cuts power when the TV enters standby
If your TV turns itself on unexpectedly, this may be related to USB device activity. Our guide on Samsung TV turns on by itself covers causes and solutions for phantom power-ons.
Best USB Drives for Samsung TV: Flash Drives & External Hard Drives
Not all USB drives perform equally on Samsung TVs. Here's what to look for and specific recommendations.
USB Flash Drive Selection Criteria
Capacity: 32GB-256GB handles most media libraries effectively. Larger drives work but check for GPT vs MBR partition formatting (Samsung TVs prefer MBR).
Speed: USB 2.0 drives work fine since Samsung TVs use USB 2.0 connections anyway. USB 3.0 drives are backward compatible but don't provide speed advantages on most TVs.
Form Factor: Compact "nano" style drives minimize protrusion from the TV, reducing the chance of accidental damage when the drive is installed.
Recommended Flash Drives
Drive | Capacity | Why It Works |
|---|---|---|
Samsung FIT Plus | 32GB-256GB | Compact design, reliable compatibility, 5-year warranty |
SanDisk Ultra | 32GB-256GB | Affordable, widely available |
Kingston DataTraveler | 32GB-128GB | Budget option, reliable performance |
External Hard Drive Requirements
For recording and large media libraries:
Minimum: 5,400 RPM hard drive
Recommended: External power supply for reliability
Connection: Use the 5V 1A (HDD) port
Capacity: 500GB-2TB (drives over 2TB may have compatibility issues)
Solid-state external drives (portable SSDs) also work well and don't require external power, but they cost more per gigabyte than traditional hard drives.
What to Avoid
USB hubs: Not supported
Drives over 2TB: May have partition table compatibility issues
Heavily partitioned drives: Single-partition drives work most reliably
Drives with encryption software: Hardware encryption can prevent recognition
For Samsung TV USB recording specifically, Samsung recommends external hard drives with their own power supply for best reliability during extended recording sessions.
Samsung TV USB Port FAQ: Your Questions Answered
Can I charge my phone from Samsung TV USB port?
Yes, you can charge a phone from a Samsung TV USB port, but charging will be slow. The standard USB port provides only 5V at 0.5A (2.5W), while the HDD port offers 5V at 1A (5W). Most modern smartphones require 10W or more for standard charging speeds, so expect very slow charging compared to a dedicated phone charger. The USB ports do stay powered in standby mode, allowing overnight trickle charging.
Why does my USB drive work on my computer but not my TV?
The most common causes are incompatible file system format (use FAT32 or exFAT for QLED TVs), unsupported video codecs inside the files, or exceeding the maximum file count (8,000 on QLED, 4,000 on Full HD TVs). Reformat the drive, check your file codecs, and ensure you haven't exceeded the file limit.
How do I safely remove a USB drive from my Samsung TV?
Press the Source button on your remote, select the USB device, press the Tools button, and select "Disconnect USB Device." Wait for the confirmation message before physically removing the drive. This prevents data corruption on the USB drive.
Can I connect multiple USB drives to my Samsung TV simultaneously?
Most Samsung TVs have 2-3 USB ports, allowing multiple drives to be connected at once. However, Samsung recommends disconnecting unused devices, as connecting multiple high-power USB devices may cause recognition issues or insufficient power delivery to individual drives.
Why are my USB ports always powered even when the TV is off?
This is intentional behavior in Samsung's Tizen OS to support quick-start features and power accessories like streaming sticks. There is no setting to disable this. The workaround is using a smart power strip to cut power completely when the TV isn't in use, or simply unplugging USB-powered accessories when not needed.
Does Samsung TV support USB-C flash drives?
Most Samsung TVs have USB Type-A ports, not USB-C. To use a USB-C flash drive, you need a USB-C to USB-A adapter. Some 2025-2026 premium models may include USB-C ports, but USB Type-A remains the standard for TV USB connectivity.
Can I watch USB content and record TV simultaneously?
No, Samsung TVs cannot play USB media files and record live TV to USB at the same time. The PVR recording function requires dedicated USB access. You can watch live TV while recording to USB, but you cannot browse or play files from another USB device during recording.
Conclusion: Maximizing Your Samsung TV USB Experience
Your Samsung TV's USB ports unlock functionality far beyond their unassuming appearance. From playing your personal movie collection to recording live broadcasts and powering streaming devices, these connectors serve as versatile expansion points for your entertainment system.
The key takeaways from this guide:
Know your port capabilities. The HDD-labeled port (5V 1A) provides double the power of standard ports - essential for external hard drives and streaming sticks.
Format correctly for your TV type. QLED and Neo QLED TVs support FAT, exFAT, and NTFS. Full HD TVs work best with FAT32. When in doubt, exFAT offers the best balance of compatibility and features.
Mind the DTS audio limitation. Samsung TVs manufactured from 2022 onward don't support DTS audio. If your video plays without sound, the audio codec is likely the culprit.
Regional restrictions affect recording. PVR and Timeshift features are disabled in the USA, Canada, and several other regions at the firmware level - this cannot be changed through settings.
For users still getting started with Samsung TV setup, USB functionality integrates naturally into the overall TV experience. And when issues arise, the troubleshooting section of this guide - combined with our comprehensive Samsung TV help guide - covers the vast majority of USB-related problems users encounter.
Whether you're building a home media server, setting up PVR recording (where available), or simply trying to watch vacation videos on the big screen, understanding your Samsung TV's USB capabilities transforms how you interact with your television.
