<pre> As it turned out a refresh rate of 30Hz can be achieved with the OSS-driver
and the right modeline:
Modeline "3840x2160_30.00" 268.06 3840 3992 4080 4112 2160 2161 2164 2173
+hsync -vsync
It is a trick to set nouveau.hdmimhz=296 instead of 297 in order to prevent
the automatic mode requiring a higher TMDS frequency to appear automatically
which blackens the screen. Once a mode with too high frequency has been set the
external monitor will stay without signal until I reboot. In a practice the
TMDS limit may neither be 225 nor 297 but somewhere in between.</pre>
