Resolution Cap on VGA? and HDMI output issues.

First question; VGA has an unlimited resolution out put correct? If not what is it limited too?

I'm trying to get 1920x1080 resolutions for my desktop and games, but my monitor only has VGA, Svideo, and HDMI.

With VGA it caps its self at 1680x1050, nothing I do will fix this no drivers reformatting etc. I don't know what it is.

With HDMI it wil do the 1920x1080p resolution (according to windows and the little info message built into my TV) BUT it only takes up the screen in a 4:3 ratio, so 25% black on the left, 50% of my tv is being taken up by the desktop and then 25% on the right is black. It doesn't even look like the pixels in the black area are turned on.

The HDMI works fine with an Xbox.

I'm using a xfx Radeon 6790 1gb

Sounds something more likely to do with the monitor/TV itself rather than the graphics drivers to me. VGA should put out 1920x1080 just fine, but certain screens have limitations. Many LCD TVs won't let the VGA PC input go above 1360(6)x768 even if the display is capable of more than that.

What screen do you have?

In the menu, there should be an option somewhere to disable all automatic scaling or an Underscan/Overscan setting. With no scaling set by the screen, your pc picture might be overscanned (in other words, the picture might be chopped off on both sides slightly), and the TV is recompensating for that by forcing it in a different ratio.
