--- Comment #20 from Elmar Stellnberger <estellnb at elstel.org> ---
Great! Stunning! Now that has worked right from the start. A little change to
radeon_dvi_mode_valid and radeon_dig_monitor_is_duallink was fully sufficient
to achieve 3840x2160 at 30 - and the mode is offered automatically by a mhz of
297.
Many thanks for hinting me, Alex! I wouldn`t have found it entirely on my own.
Are there any chances to get a well prepared patch for the radeon.hdmimhz
parameter into the final 4.5.0 release?
