Is response time actually involved in LCD picture blur? Do those fancy new motion enhancement features actually degrade your image quality? Is it actually important to your eyes that you can spot motion blur in still images? These are the questions that ExtremeTech decided to answer when they investigate the issue of motion blur on LCD screens. Their testing involved eight LCDs, two plasmas, one Sony Professional HD Trinitron Studio Monitor and a CRT
for reference. Read on to see just how response time, 60- or 120-Hz refresh rates, strobed LED backlighting, and motion enhancement processing really effect your viewing of moving video.
"Although all display technologies have their own unique strengths and steadily improve over time, users'
memories of their initial weaknesses and limitations can plague them forever. The best examples of this
effect are plasma displays, with their so-called "burn-in" problem (which is actually uneven aging),
something that was technically overcome many years ago but which lingers like an 800-pound gorilla that
still threatens to kill this excellent technology. Plasma manufacturers bear much of the blame because
