I do have a VGA input on my TV but it will not take up the full screen if
you use it. Refering to what you where talking about Michael should I get a
cable to convert the VGA to something else? If so what input should I shoot
for? I do like the idea of using the VGA output anyhow b/c every computer
already comes with this. Even if I use the VGA out won't I still have to
tell it the specs for my Display with a modeline since it is not standard?
Steve, I have seen where some people are using different resolutions for
different content but how do you control this? Also if you are using Myth in
on a widescreen display what do you use for the theme. Thanks for the help I
think I am starting to understand a little better.
