Consider the alternatives: If you can live with a tabletop set that's 10 to 18 inches--rather than 4 to 7 inches--deep, DLP (digital light-processing) rear-projection sets can deliver solid performance in similar screen sizes and at lower prices. You just don't hear about them as much because they're not as sexy.

Think HDMI: Get a set with at least three or four HDMI (High-Definition Multimedia Interface) inputs. Doing so will ensure that you can connect it to multiple HD sources such as digital cable boxes, satellite receivers, and Blu-ray Disc players. Try to choose a set with at least some front- or side-accessible ports; such conveniences can make life much easier when it comes time to connect a device.

Compare displays using various input sources: Most flat-panel displays will handle HDTV and DVD signals well, but mediocre cable and satellite signals will give some of them fits. Don't make a buying decision based solely on images generated from pristine sources, or based on what you see in the store.

Look for good black tones: When you're comparison shopping, bring along a DVD of a movie containing some dimly lit night scenes. Use it to check for good black reproduction and the ability to render detail in near-darkness.
