I still want to try 4x3... ;) If the thing acts like a plug-and-play monitor, then just maybe, read-edid might work: http://web.onetel.net.uk/~elephant/john///programs/linux/index.html
(this is what I reached after redirect when following the link in its docs) This is a really weird package though; it was only available as source, and even when that's compiled, you run 'make read-edid' while root (so you can ask the display) and it will try to cook up some modelines for you. Hasn't caused me problems, but hasn't worked on every monitor, either. > I have now realised that the old Pentium120 will then possibly NOT have > a fixed dotclock, it can likely depend on the scaled resolution, thus > for 320x200 it will have a dotclock that is necessary to output > 640x600(?)
