using a tv at 720p is fine. the higher the resolution you go the smaller the text becomes, because you are fitting more on your screen. i currently have 2 32in tv. one with vga input, the other with hdmi. one tv im using 1360 x 768, the other 1280 x 720, and both are looking great. the text is clear and big enough to read from5-10 ft away, assuming you have good eyes. using native resolution is best, but using any widescreen resolution below the native would be fine as well. my opinion would be to use which ever resolution that is easiest to read and looks the clearest. and remember, when you hook a tv up to your pc you might get some of the screen going past the boarders of your tv, cutting off some of the task bar and some of your desktop. this is common, and easy to fix. just go into your video cards control panel and look for the scaling option to adjust it.
