I think I already tried 1024x768 @ 60 Hz and 1024x768 @ 70 Hz--unless I entered the video= argument wrong. That remains a possibility, but until I find out how to list them right, I can't say for sure. On whether my monitor supports multiple refresh rates. This excerpt from the manual seems relevant, doesn't it? "1.2 Features a. Multi-scanning at horizontal frequencies of 31KHz to 64KHz and vertical frequencies of 60Hz to 75Hz."
