HDTV tests pit fantasy land specs against real world performance -- guess what happens
Good luck keeping up with the ever changing specs on the latest HDTVs, but as the numbers get more impressive, are the displays actually improving in any noticeable way? Dr. Raymond Soneira , president of DisplayMate, goes about breaking down many of the more often misused and misleading technical buzzwords in an article on MaximumPC. If you're wondering how manufacturers have advanced contrast ratios from thousands, to millions, to unlimited over the space of just a few years, there's a breakdown of what "dynamic contrast ratio" actually measures and why it's worth ignoring -- unless you watch your TV when it's only displaying one color at a time. When it comes to colors, some of the most scathing words were pointed towards Sharp's Quattron quad-pixel technology, which "can only decrease picture quality and accuracy!" Whether you believe the good Dr., a glistening review or Cmdr. Sulu, the factual heat burned hottest during a test of motion blur compared on LCDs, LED LCDs, plasmas and even a pro CRT. While additional motion processing and upgraded internals on newer HDTVs can help in many other ways, viewers couldn't detect any blur caused by a display even on an old 60Hz set, despite newer and faster 120Hz, 240Hz and 600Hz (plasma) sets claiming their technology helped them eliminate it. You'll need a minute to read through for the full details but it's a good, and unfortunately necessary, reminder to keep your eyes on the display and not just the spec sheet (just make sure you're getting a proper look that represents the way you watch TV at home first).
BenQ debuts GL series of LCDs with 12,000,000:1 dynamic contrast ratio
Alright, so we all know (or should know) that a manufacturer's stated contrast ratio isn't the best way to judge the quality of an LCD, but we've got to hand it to BenQ with its new GL series of monitors, which boast a ridiculous 12,000,000:1 dynamic contrast ratio. That, as you might have guessed, is apparently the industry's highest and, according to BenQ, helps to add "color depth and definition to darkened and complex visuals." Otherwise, the 18.5-inch GL930, 19-inch GL931, 20-inch GL2030, 21.5-inch GL2230 and 22-inch GL2231 models each look to pack some decidedly more standard specs, including a 5ms response time, LED backlighting, varying amounts of ports depending on the model, and a 1,600 x 900 resolution on the 20-incher (complete specs on all the models aren't available yet). That 20-inch GL2030 model is also the first of the lot to roll out (sometime this month), while the rest will be available in July.
