Unfortunately "videogen" has compiled-in limits for width, height and
refresh rate so can't be used directly here. But, I grabbed the source
and patched for that, and then got the modeline:

% ./videogen -v -m=3840x2160 -mdc=290.000 -mhf=67.5 -hfp=176 -hbp=296 -vfp=8 -vbp=72 -mvf=30

Modeline "3840x2160" 290.00 3840 3960 4104 4800 2160 2168 2171 2274 # 290 MHz, 60.4 kHz, 26.6 Hz

.. if that's any use for you

Ralph.
