LCD TVs improve

Many new LCD TVs with 120Hz or 240Hz technology have little or none of the motion blur that's often seen on models with a 60Hz refresh rate. It's now common to find 120Hz on all but the cheapest LCD TVs; 240Hz is mostly on pricier sets, including 3D TVs. And more LCDs, usually higher-priced models, have LED backlights rather than fluorescents. TVs with full-array LEDs and local dimming might display deeper blacks than typical LCDs. Models with edge LEDs have superslim profiles of about an inch. Both types of LEDs are energy efficient.

Our advice: A 60Hz LCD set should satisfy casual viewers. But consider a 120Hz model if the price is right or a 240Hz set if you're a critical viewer. LED backlighting isn't inherently superior, but it's worth paying more for it if you want the thinnest profile and lower utility bills.
