Since it's "this particular monitor" they may have fixed something relating to EDID parsing... did you look at the EDID from the monitor to see if it actually makes sense. This can be achieved with 'get-edid' and 'edid-decode' on Ubuntu. "xrandx --verbose" also give a pretty complete report.
How easy is it to update to the lastest Nouveau driver, is there a PPA somewhere?

Great news! Can you also test deep color (e.g. 10 bpp) and HFR (60 Hz)?

Maybe you should say which refresh rate. The Maxwell ones (even the gen1 i think) should be able to use 60 hz.

Phoronix: 4K HDMI Appears To Work Much Better With Nouveau On Linux 4.5
While I'm in the middle of a big Nouveau Linux 4.4 vs. Nouveau Linux 4.5 vs. NVIDIA proprietary driver comparison with multiple NVIDIA GeForce graphics cards, I just wanted to pass along a bit of good, non-performance news about Nouveau on Linux 4.5...
