X won't use a resolution that needs a higher dot-clock than your video card can provide. it won't use a bit depth that needs more video ram than your card can supply. but lying about HorizSync and VertRefresh can smoke your monitor. do NOT blindly tell X that your monitor can do a vsync of 100 if it can't do a vsync of 100. take the guess work out of this thread. please post your hardware. pete -- Make everything as simple as possible, but no simpler. -- Albert Einstein GPG Instructions: http://www.dirac.org/linux/gpg GPG Fingerprint: B9F1 6CF3 47C4 7CD8 D33E 70A9 A3B9 1945 67EA 951D _______________________________________________ vox-tech mailing list [EMAIL PROTECTED] http://lists.lugod.org/mailman/listinfo/vox-tech
