Thanks for the tip. Is there any way to fine-tune the results? On my
Sony projector TV (with HDMI input), the automatically generated
modeline (from EDID information, I might add) results in the graphics
screen going out-of-bounds of the physical display.

One of the nice things I've learned about X Windows is that the standard
resolutions (1280x1024, 800x600, 1680x1050, etc.) aren't fixed
(depending on the display device). That one can come up with arbitrary
resolutions so long as the display supports it. There was a time when I
would find the maximum resolution that my video card and display screen
could use while maintaining a refresh rate of 75Hz. It was all done by
hand and my bumbling about with numbers. Are those days gone? Or will
that capability be somehow revived through a GUI program that will take
care of the mathematical part of computing modelines (which used to be
done by hand)?

It really is too bad that the Modes can't be changed on the fly (without
needing an X restart).
