All 1080p HDTVs have the same screen resolution — 1920 x 1080 pixels — but they don't always deliver equal picture clarity. Most sets can display absolutely flawless still images. But moving objects on screen are more difficult to display cleanly. This can be especially apparent if you watch lots of things with fast action, like video games or sports.
What you should know about motion handling:
Motion handling has always been a strong point for plasma TVs. Because of the way plasma TVs create the picture, there's no lag or ghosting, and motion looks very natural and crisp. So if clear, true-to-life on-screen motion is a high priority for you, you should definitely consider a plasma.
For LCD TVs, on the other hand, motion handling has traditionally been difficult because of the way they create the picture. But many of today's LCD TVs are better equipped to display fast motion without blur. If you want smoother motion with an LCD, look for a model with a 120Hz or 240Hz refresh rate. These sets include sophisticated processing that can virtually eliminate motion blur.
