Hi! Depending on the TV you have, the visible area of the screen may be considerably less than the max resolution.
With TV images one rarely notices a few pixels missing on the edges, but when developing interfaces it really shows when the starts of words are cut off on the left side. The amount cut off is not necessarily predictable - it can depend on the TV set. For this reason many STBs allow you to adjust the image postion by setting margins. Most Windows Drivers for Video Cards also let you re-center the TV Image in some way. You may be able to change the position of your image by playing with the modeline... Increase the margins a little... All the same, it is a good policy to develop GUIs for TV leaving a 5-10 pixel margin, for the users whose TVs aren't adjusted perfectly...
