While my Nvidia G96GLM [Quadro FX 770M] yields 3840x2160@30 well under Windows
7 certain problems appear when trying to make use of that mode under
nouveau/Linux. The 3840x2160_23.00 mode described in Bug 93405 works well also
with the G96GLM; here even without any nouveau.hdmimhz parameter.
  A 3840x2160@30 mode appears automatically as soon as I specify
nouveau.hdmimhz=297. However when I select it the external monitor turns white
with a black bar at the bottom instead of showing the correct screen content.
Trying predefined modelines by cvt, gtf or the arachnoid modeline calculator
(online) does not yield any usable result either (blackscreens).
  Unfortunately many 4K screens only support at minimum 30Hz and not 23Hz so
that this issue is a real problem. Besides this heavy mode switching can still
lead to crashes/hangs while the 3840x2160@30-interlaced mode worked well even
without a hdmimhz parameter. However for interlaced modes the mouse pointer
still disappears.
