As LCD and plasma vie for popularity and picture-quality bragging rights, one perceived weakness of the LCD camp has provided a reason for TV makers to charge more for step-up models: image blurring. Higher refresh rates like 120Hz and now aim to clean up blurring with newfangled technology, and Toshiba's ZV650U series is one of the least expensive of such sets available.
Unlike such sets by Samsung and Sony, the Toshiba ZV650U uses a scanning backlight to reduce blurring--and, in fact, the company is careful to call its technology a "240Hz effect" to differentiate it from true 240Hz models. In most normal program material we find it nearly impossible to appreciate the antiblurring effect, but some people are really bummed by blurring, and for them the new LCDs--or perhaps the nearly blur-free images produced by plasmas--hold appeal.
Unfortunately for this particular Toshiba, high-tech-sounding processing can't overcome lighter black levels and a few other picture quality foibles. On the other hand, for those dead set on LCD who don't mind paying a bit extra for 240Hz, the relatively low price of the Toshiba ZV650U series makes it worth considering.
