Marcus Whitfield

Marcus has spent the last 11 years measuring, calibrating, and tearing apart consumer televisions - first as a home-theatre installer in the Austin metro, then as a freelance ISF-certified calibrator for custom-install firms across Texas. He founded the Tech Junctions testing room in 2024 with one rule: every panel we write about has to sit in a real living room with real lamps, real reflections, and real family movie nights before a single word of review copy is drafted. Marcus owns the test methodology, signs off on brand comparisons, and re-measures any panel where reader reports disagree with our findings. He wrote his first calibration walkthrough in 2015 and still personally verifies every picture-settings guide published on the site. Off-hours he's restoring CRT broadcast monitors and losing arguments about local-dimming zones on AVS Forum.
