Buyer’s FAQ
Short, straight answers to the questions people ask before they choose a TV: how much to spend, what size to get, and which features are worth paying for.
31 questions in 9 topics
Budget and value
How much to spend and when to spend it.
How much should I spend on a TV?
For most living rooms, a very good 55-65 inch 4K TV sits in the mid-range bracket, and that's where value is best—you get strong brightness, local dimming, and full gaming features without paying flagship prices. Spend more only if you specifically want the best contrast (OLED), the highest brightness for a sunny room, or the largest screen sizes. Below the budget tier, expect compromises in brightness, motion, and processing.
Are expensive flagship TVs actually worth it?
They're worth it if you watch in a controlled room and care about reference-level picture quality, or if you need extreme brightness for a bright space. For typical mixed viewing, a good mid-range set delivers 80-90% of the experience for a fraction of the cost. The biggest real-world upgrades are panel type (OLED or Mini-LED) and brightness—not marketing features.
When is the best time to buy a TV?
The best deals land during Black Friday and Cyber Monday (late November), Super Bowl season (late January to early February), and Amazon Prime Day (summer). New models typically launch in spring, which pushes prior-year models to their lowest prices from spring through summer—often the sweet spot for value.
Should I buy last year's model to save money?
Usually yes. Year-over-year TV improvements are often incremental, so a previous-generation flagship frequently beats a current-year mid-ranger at the same price. Just check that the older model still supports the features you care about—such as the gaming or HDR formats your devices use—before buying.
Screen size and placement
Getting the size and mounting right for your room.
What size TV should I buy?
Match the size to your seating distance. As a rough guide for 4K, a comfortable screen size in inches is roughly your viewing distance in inches divided by 1.6 for an immersive feel, or 2 for a relaxed one. Most people under-size: with 4K you can go bigger than you think without seeing pixels. Our TV Size Calculator gives you an exact range for your distance.
How high should I mount my TV?
Aim for the center of the screen to sit near eye level when you're seated—typically around 40-48 inches from the floor to the screen's center for a standard sofa. Mounting too high (a common mistake above fireplaces) causes neck strain; if you must mount high, use a tilting mount to angle the screen down.
Can a TV be too big for a room?
Yes, but mostly on 1080p sets, where sitting too close to a large screen reveals visible pixels. On 4K it's far harder to oversize—the limiting factors become comfortable neck movement and budget rather than image quality. If the screen fills more than about a 40-degree field of view, it may feel too large for casual viewing.
Panel and display technology
OLED, QLED, Mini-LED, refresh rate and resolution.
OLED vs QLED vs Mini-LED—which is best?
OLED has perfect blacks, infinite contrast, and the best viewing angles, making it ideal for darker rooms and movie lovers. Mini-LED and QLED (both LCD-based) get much brighter, so they fight glare better in sunny rooms and resist burn-in. There's no single winner: choose OLED for contrast in controlled light, and a high-nit Mini-LED for brightness in a bright room.
What's the difference between LED, QLED, and OLED?
LED and QLED are both LCD TVs lit by a backlight—QLED just adds a quantum-dot layer for richer, brighter color. OLED is a completely different technology where each pixel makes its own light and can switch off entirely, which is why OLED achieves perfect blacks that backlit LCDs can only approximate with local dimming.
Is an 8K TV worth buying yet?
Not for most people. Native 8K content is still extremely rare, so most of the benefit comes from upscaling lower-resolution sources. At normal living-room sizes and distances, the jump from 4K to 8K is hard to notice. Spend the money on a better 4K panel—brightness and contrast matter far more than extra resolution today.
Do I need a 120Hz TV?
For movies and regular TV, no—that content is 24-60fps and a 60Hz panel handles it fine. A 120Hz panel matters mainly for gaming on a PS5, Xbox Series X, or gaming PC that can output high frame rates, where it delivers noticeably smoother, more responsive motion. If you don't game at high frame rates, don't pay extra for it.
Picture quality
Brightness, contrast, motion and getting an accurate picture.
How many nits of brightness do I need?
For everyday SDR viewing, 250-400 nits suits an average living room, while a bright, sunny room benefits from 400 nits or more. For HDR, look for 600+ nits of peak brightness as a solid baseline and 1,000+ to make highlights truly pop. Our Brightness Estimator turns your room's lighting into a specific target.
What is local dimming and do I need it?
Local dimming lets an LCD TV dim parts of its backlight independently to deepen blacks and boost contrast. On LCD/LED TVs it makes a big difference, and more dimming zones generally means better results with less blooming. OLEDs don't need it because each pixel controls its own light. If you're buying an LCD TV, good local dimming is one of the most worthwhile features.
Why does my TV look different at home than in the store?
Stores use a bright, punchy 'Vivid' or demo mode under intense lighting to grab attention—it's rarely accurate. At home, switch to the Movie, Cinema, or Filmmaker picture mode for the most natural, intended image. It may look softer or warmer at first, but it's far closer to how content was meant to be seen.
Should I turn off motion smoothing?
For movies and TV, most people should turn it off or set it low—heavy motion smoothing creates the artificial 'soap opera effect' that makes film look like cheap video. Some viewers like a touch of it for live sports. It's a personal preference, so try both, but films are designed to be watched at their native 24fps cadence.
HDR and formats
What the HDR badges mean and which ones matter.
What is HDR and do I need it?
HDR (High Dynamic Range) expands the range between the darkest and brightest parts of the image and widens the color palette, for more lifelike, punchy pictures. It's now standard on most 4K content and worth having—but the quality of HDR depends heavily on the TV's brightness and contrast. A cheap TV with an HDR logo but low brightness won't show much benefit.
Dolby Vision vs HDR10+—does the format matter?
Both add dynamic, scene-by-scene optimization on top of the baseline HDR10 format, and both look great. Dolby Vision is the more widely supported premium format (Netflix, Disney+, Apple TV+), while HDR10+ is backed mainly by Samsung and Amazon Prime Video. If you have strong preferences in streaming services, check which format your TV supports, but every HDR TV supports baseline HDR10 regardless.
Will my new TV play 4K HDR streaming and Blu-rays?
Any current 4K TV will stream 4K HDR from the major apps, assuming a fast enough internet connection and the right subscription tier. For 4K Blu-ray discs you need a dedicated 4K Blu-ray player—the TV itself doesn't play discs. Check that the TV supports the HDR formats (Dolby Vision or HDR10+) your content and players use.
Smart TV and apps
Platforms, streaming devices and privacy.
Which smart TV platform is best?
Google TV and Roku TV have the broadest app support and clean interfaces; LG's webOS and Samsung's Tizen are polished and fast on their respective sets; Fire TV integrates tightly with Amazon. All cover the major streaming apps, so platform is rarely a dealbreaker—but if you rely on a niche app or a specific voice assistant, confirm support before buying.
Do I still need a separate streaming device?
Often not—built-in platforms cover most needs. But a dedicated streamer (Apple TV 4K, Roku, Fire TV, Chromecast) can be faster, get updates longer, and offer apps your TV lacks. They're also handy if your TV's built-in platform feels sluggish or stops receiving app updates after a few years.
Do smart TVs collect my data?
Most do, through a feature called ACR (Automatic Content Recognition) that tracks what you watch for advertising and recommendations. You can usually limit this in the TV's privacy settings by disabling ACR, viewing-information services, and personalized ads. It won't disable core functions, and it's worth reviewing these settings during setup.
Gaming
What matters for PS5, Xbox and PC gaming.
What should I look for in a gaming TV?
Prioritize low input lag (under ~15ms in Game mode), a 120Hz panel, Variable Refresh Rate (VRR), and Auto Low Latency Mode (ALLM). For the latest consoles and high-frame-rate PC gaming, you'll also want HDMI 2.1 ports. OLED panels add near-instant response times for the sharpest motion.
Do I need HDMI 2.1 for a PS5 or Xbox Series X?
To get 4K at 120Hz from a PS5 or Xbox Series X, yes—that requires an HDMI 2.1 port with enough bandwidth. You can still play at 4K/60 on HDMI 2.0, but you'll miss high-frame-rate modes and some VRR benefits. Also check how many 2.1 ports the TV has if you're connecting more than one device.
What do VRR and ALLM actually do?
VRR (Variable Refresh Rate) syncs the TV's refresh rate to the game's fluctuating frame rate, eliminating screen tearing and stutter. ALLM (Auto Low Latency Mode) automatically switches the TV into its low-lag Game mode when a console starts a game, then back out for video—so you get responsive gaming without changing settings by hand.
Sound and connections
Soundbars, eARC and how many ports you need.
Do I need a soundbar?
For most people, yes—modern TVs are so thin there's little room for good speakers, so built-in sound is usually adequate at best. Even an entry-level soundbar is a major upgrade for clarity and dialogue. If you want immersive surround or Dolby Atmos, step up to a soundbar with up-firing speakers or a full surround system.
What is eARC and do I need it?
eARC (Enhanced Audio Return Channel) sends high-bandwidth, lossless audio—including Dolby Atmos and DTS:X—from the TV to a soundbar or receiver over a single HDMI cable. You need it if you want the best surround formats passed through your TV to your sound system. Both the TV and the audio device must support eARC, and you should use a high-speed HDMI cable.
How many HDMI ports do I need?
Count your devices—game console, streaming box, Blu-ray player, soundbar—and add one for the future. Four HDMI ports is comfortable; three is a common minimum. If you game on a current console, make sure at least one (ideally two) of those ports is full-bandwidth HDMI 2.1, since one is often used by the soundbar via eARC.
Buying and ownership
Lifespan, burn-in, warranties and refurbished sets.
How long do TVs last?
A modern TV typically lasts 7-10 years of normal use before brightness fades or you simply want newer features. Panels are rated for tens of thousands of hours. In practice, most people replace a TV because technology has moved on—not because it failed.
Should I worry about OLED burn-in?
For normal, varied viewing, burn-in is unlikely on modern OLEDs, which include pixel-shifting and refresh routines to prevent it. The risk rises only with many hours of the same static element—a channel logo or a fixed game HUD—day after day. If you watch a wide mix of content, OLED is safe; if you'll display a static image for hours daily, a Mini-LED or QLED is the safer choice.
Do I need an extended warranty?
Usually not. TVs that work out of the box rarely fail within the extended-warranty window, and your card or consumer-protection laws may already add coverage. An extended warranty can make sense for very large, expensive TVs or if accidental damage protection matters to you—but for most purchases the cost outweighs the likely benefit.
Is it safe to buy a refurbished or open-box TV?
It can be a great value if it's manufacturer-refurbished or sold by a reputable retailer with a clear return policy and warranty. Certified refurbished units are tested and often as good as new. Be more cautious with third-party 'as-is' listings that lack a warranty, and always inspect the screen for dead pixels and uniformity issues as soon as it arrives.
