I have two problems:

1. In windows when set 1920x1080, screen cut about 100 pixels on right side
when running exactly same resolution on laptop everything is fine

2. In LFS I can't set resolution more than 1600x1200, tried editing cfg file, and card_cfg

windows 7 32-bit, 8600gt

There's probably an 'overscan correction' option in nvidia CP.

Are you using a TV? Some of them don't do those signals properly and over/underscan like that.

Can't find overscan correction in my nvidia CP
Yes, using TV.

I think that i don't have option in LFS to set that resolution because windows don't recongize that monitor could manage with that resolution. I setd this resolution trought nvidia control panel.
For some reason on PC when using 1920x1200 there is no 'overscan' (but this is not native TV resolution)

Also I'm using DVI to VGA adapter on PC, on laptop is directly VGA.
So, is there any way to fix this

installed XP, there everything works but for some reason cant find my audio card ...
