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@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!!)
