Re: Graphic card gets hot
So it's the server.
And not the rotation.
Or the root window size.
Or the frequency sum.
Despite the last item, try to run all outputs at XGA (1024x678) as a somewhat drastic measure to see whether the bandwidth is relevant.

I have tried these:
1. Turn 1080p@50hz to 1024x768 -> power change to 90W and P0
2. Turn both 1080p@50hz and 2k@60hz to 1024x768 -> 90W and P0
3. Turn all three to 1024x768 -> the 4k monitor drops to 30hz automatically, and cant adjust to 60hz(no this option in settings anymore...) and power drop to 26W and P8
4. Undo everything, then just turn 4k@60hz to 30hz -> power 28W and P8

Re: Graphic card gets hot

So it is the bandwidth - at least something (you may check the frequency on windows)
Not sure whether you posted and xorg log or verbose xrandr output (to see what modeline is actually used) but you could try https://wiki.archlinux.org/title/Xrandr … esolutions with
% cvt12 3840 2160 60 -b
# 3840x2160 @ 60.000 Hz Reduced Blank (CVT) field rate 60.000 Hz; hsync: 133.320 kHz; pclk: 522.61 MHz
Modeline "3840x2160_60.00_rb2" 522.61 3840 3848 3880 3920 2160 2208 2216 2222 +hsync -vsyncwhich provides about a 25% data reduction compared to the full blanking (if that's currently in use)

Re: Graphic card gets hot
The point is that this is a modeline w/ reduced blanking - if the present is not (not visible in a brief xrandr query, try --verbose), it operates on a 712.75 MHz pclk (in comparism to the 522.61 MHz of the one w/ teh reduced modeline) what is a metric of "how much has the GPU to work to feed this output"

Ahh I see, this is the output for xrandr --verbose

cvt -r 3840 2160instead?

Re: Graphic card gets hot
https://aur.archlinux.org/packages/cvt12-git but yon don't have to run it
1. cause I posted the resulting modeline that you can use w/ the wiki link
2. because the existing modeline is at 533.250MHz (the cvt1.0 reduced blanking) and I don't assume that a <5% drop will do much help here 
Does windows run the output at 30 or at 60 Hz?

I see...
Windows runs at 4k@60hz, 2k@60hz, 1080p@60hz at about 27W, p8
compare to arch 4k@60, 2k@60, 1080p@60 at about 90W, p0;
4k@60, 2k@60, 1080p@50 at about 64W, p3

Section "Device"

Driver "nvidia"
Option "UseNvKmsCompositionPipeline" "false" # https://forums.developer.nvidia.com/t/various-all-distros-numerous-performance-rendering-issues-on-390-25/57733/110
EndSectionbut I neither know whether that's still supported nor whether it's the root of the problem.

I add this to the file and reboot, but it doesn't help QAQ
Update:
Some really weird things just happened:
I am using the machine as usual (just using firefox and nothing else is opened), and the monitors (three of them) just flashed and goes black, then, the primary one (4k@60), just goes back to normal, and the other two just switched their displays (everything, including desktop wallpaper, widget, ...). I tried to reboot, but it doesn't fix this, I have checked nvidia-settings and system settings display panel, nothing changed in there...
