You are, in fact, missing something. To use the oddball modes, such as 800x600x16, 640x480x256, and (I think) 640x400x256, you must have a MultiSynching monitor. The sync rates required are higher than normal VGA monitors can handle. I'll try to find the manual for more details, but that's the basic story... -- Tom Egelston Internet: tom@uokmax.ecn.uoknor.edu Disclaimer: Don't get so stressed!!
