It should matter. Depending on what display board you have, you may be limited in the pixel frequencies. > If not, I have a Matrox Millennium G200 8Mb PCI on the way which > will definitely support the resolution I want. I don't think you'll have trouble with either of these boards. I have a Millenium running at 1600x1200, and I think it has programmable clocks, but I'm currently in an aeroplane and don't have access to the machine. > Does anyone have a GDM-500PS or comparable monitor who knows the > modeline I need? Since you already have 1600x1200 running OK, you should be able to play around with it. There's a detailled description in my "The Complete FreeBSD", and some of that is also in an article (not Daemon's Advocate) that I published at http://www.daemonnews.org/, but briefly you can play around with these values: Modeline "1600x1200" 198.000 Try increasing, say to 225. Your frame frequency will increase accordingly. 1600 1616 1776 2112 Decrease in steps of 16, but not lower than about 1808. Your frame frequency will increase inversely. 1200 1201 1204 1250 Decrease in steps of 1, but not lower than about 1210. Your frame frequency will increase inversely. +hsync +vsync I don't think you need these at all, but they won't have any effect on your display if you remove them. > Does anyone know where I can get a listing of modelines for standard > resolutions?

They still rather assume that you're going to get out an oscilloscope and do it yourself :-) Greg -- When replying to this message, please copy the original recipients.
