my screen and tv guide are zoomed in.How can i fix it
Sorry to hear your picture is zoomed in there, that does sound annoying. Changing this setting is different depending on the type of cable box you have. One thing you can try if you have an Atlas remote with one red button at the top is pushing the aspect button on your remote, which is also labelled #. It's at near the bottom right of the remote.
If you have an HD guide box, you can try the steps outlined here: High Definition Guide - Video Setup,
otherwise you're going to want to try your TV's original remote, looking for a picture size setting in the menus or as an actual remote button.
Hope this helps, please let us know how it goes!
