nvidia sync problems with 1280x1024 lcd

[dabicho]

I am having problems with nvidia with my (new) lcd display.

This is an:
MSI nVidia GeForce FX 5700 and
ViewSonic 18" VX800 lcd display

Operating systems are both gentoo linux and Fedora Core1.

The problem presents with both XFree86 and just released xorg-x11

What happens is that the refresh loses syncronization very frequently, specially if I have a (more or less) complex background and maximized windows.
Most times, the resync lasts only 2 secs, but sometimes it turns off the monitor.


Another problem presents when I try to watch full-screen movies with any linux video player (be it mplayer, xine or others) in full screen mode, which makes for a fuzzy horizontal lines. (in teh case of mplayer, with any video output except -gl2)

Here are my (gentoo) XF86Config and a log file


Any pointerwould be very much appreciated.
