No video in 640x480 mode

[slackware1995]

Hardware:
nVidia GeForce2mx400 AGP
Proview 19" monitor

Whenever a program (ie game) or I manually switch to 640x480 the screen blanks and the power light flashes on the monitor. Because alot of games (especially older games) default to starting in 640x480, I can't play them.

Any ideas on how to fix this?

Maybe when ur card switches to 640x480 mode the monitor goes out of sync because of high refresh rate. Check the refresh rates supported by your monitor against those of your video card. There's a huge difference between them. You can always try to delete the monitor device and let windows find it again, as a plug n' play device or use the monitor drivers.
