Greetings
Running a debian testing system
$ uname -r
5.4.0-4-amd64
with 2 graphics cards.
The one I'm working on is a: GP 107 Nvidia GTX 1050 Ti
Asus ROG GeForce GX 1050 Ti Strix-GTX1050 Ti with 2 - DVI plus 1 DP1.4
and I HDMI2.0 ports (four in total).
I have been running 2 1920x1080 monitors on this card (and its
previous nvidia 570) for quite some time. Been running nouveau for the
last about 4 years as my last nvidia 570 (started with 3) is EOL by
nvidia.
Have gotten quite comfortable using xrandr setting up the second card
(the nvidia 570) and its 2 monitors. Nouveau software is:
xserver-xorg-video-nouveau -> 1:1.0.16-1 ;
xserver-xorg -> 1:7.7+21 ; and libdrm-nouveau2:amd64 -> 2.4.102-1 .
I want to add a 4k TV onto the HDMI port on card #1.
Can't seem to get the card and the TV talking.
Tried a number of things in xrandr:

memyself at debianone:~$ xrandr --output HDMI-1-2 --mode 3840x2160_60.00
xrandr: cannot find crtc for output HDMI-1-2
One possibility - - - - screen 0 is only 3840 x 3000 (which covers the
previous 4 monitors).
I think I need to stretch screen 0 to 7680 x 3000 for starters.
What else do I need to do to get the hdmi port talking to the TV?
TIA
(Hopefully the question is not inappropriate is so please advise!!!!
If more information is needed please advise!!)

(You need 597mhz to get 4k at 60.) Ben was able to figure out what was wrong and fix it: commit a1ef8bad506e4ffa0c57ac5f8cb99ab5cbc3b1fc Author: Ben Skeggs <bskeggs at redhat.com> Date: Fri May 29 15:18:47 2020 +1000 drm/nouveau/disp/gm200-: fix NV_PDISP_SOR_HDMI2_CTRL(n) selection I believe this change is in kernel v5.8. If you don't want to upgrade, just ensure you pick a 30hz mode-line for that display, which should enable 4k to work. Also it looks like you have both GPUs plugged in, and slaving one off the other. If possible, I'd recommend to keep everything on one GPU. The DP port can (most likely) be used for HDMI or DVI with a passive converter (not sure if it can be used with HDMI 2.0 though). Having remote displays is not a great experience (it does work though, and better than nothing in cases that require it). Cheers, -ilia
