HDTV resolution comes in two numbers, which are 720 and 1080. For a TV set to be a true a HDTV it must display 720 horizontal lines of resolution of course that means sets that are 1080 can display 1080 horizontal lines. 1080 will provide you with more clarity and more details. You will also find an "I" or a "p" after the above numbers. "I" stands for the lines being filled by the television whereas the "p" stands for the where the lines are filled consecutively.
One thing to remember, a 1080 set can display all images from 1080 and lower, so you can view all signals even if they are delivered in 720. At this time, there are not that many sources for 1080 available, only with high definition DVD's. Not even your satellite or cable service is broadcasting in 1080.
The major thing to consider when buying your HDTV is what you will be watching and where you will be placing the set. If you purchase a large HDTV set and it is too large for the room, the picture quality is certainly going to be lacking. The reason this is true is walk up close to any HDTV, you will be seeing things that are not there if you are at the optimal viewing distance. This is often referred to as the screen door effect. You may notice small little dots of various colors that do not actually blend with the scene on the screen. In order to have the best quality picture you must have the correct size HDTV for the viewing area.
