(be warned; videogen sucks. it's downright broken in some cases; but it's a command-line tool that does the calculations for you, and can get you decent starting points.) never used kvideogen; tho I hear it's good. wasn't available from its web site, last I looked. > Xvidtune works OK, but it's not really necessary, unless you have a > REALLY broken monitor, one that doesn't report it's capabilities > correctly to X. yep. it's not a tool for the newbie.

(which is why I'm contributing back, by posting config info for wacky monitors that I've gotten to work). or else the manufacturer's website; or there may even be a file in your linux distro that has information about monitors. >There is documentation in X to do this.
