It looks like something is going wrong with the PLL calculation.

I can confirm to have this problem too with the intel_extreme graphics driver, my monitor complains with a message saying "Input Not Supported" even though Haiku still works and displays as normal behind the dialog.

@CodeForEvolution: different problem, please open your own ticket and attach syslogs (both from current nightly and last known working one).

Please try with hrev51185 or newer.

@pulkomandy You were probably right with this being a different issue, as this patch did not work for me, I will open a new ticket for my issue.
