It is plugged into the *secondary* GPU, and does not report any 4k@60 modes in the EDID (well, it does report 4k@60 YUV 4:2:0 modes, but we don't support those in nouveau at this time). Whether that's because the monitor itself doesn't support HDMI 2.0, or you plugged it into your old GPU which does not support HDMI 2.0, I couldn't say from just this output. What I can say is that no amount of modelines will get you 4k@60 in this setup with nouveau. > 3840x2160_60.00 (0x6ce) 712.750MHz -HSync +VSync > h: width 3840 start 4160 end 4576 total 5312 skew 0 clock 134.18KHz > v: height 2160 start 2163 end 2168 total 2237 clock 59.98Hz > 3840x2160R (0x70c) 533.000MHz +HSync -VSync > h: width 3840 start 3888 end 3920 total 4000 skew 0 clock 133.25KHz > v: height 2160 start 2163 end 2168 total 2222 clock 59.97Hz And this is how I know you've messed with modelines. The whole point of the above question was to see the pre-messing-with-modelines state. This is not the default setup. The NVIDIA GTX 570 can only handle up to 225mhz by default over HDMI, which isn't enough for the 4k@30 modes either. If you think it can handle more, you can try to override that with the hdmimhz parameter. However I'd strongly recommend plugging the 4k screen into the GTX 1050, as even if it did work on the secondary GPU, sending a 4k screen to a remote GPU is really not a great idea.
