QN800C and QN700B also have this issue. Turning off "game mode" and making sure "Input Signal Plus" is on should allow 8k@60 and 4k@119.88 to sync. Although then they'll fail to recover from a screen saver blanking..
That is a good hint. After turning off Game Mode, it worked, but after rebooting my computer, it stopped working again. I will debug a little further...
535.54.03 seems to be better at syncing 8k@60 and 4k@120 on Samsung TVs but still has issues with DPMS.
This repro's every time for me on a dual TV setup:
Also forcing dpms to off xset dpms force off
and waiting some time before waking will sometimes lock the system requiring a hard reset.
Might have a +1, might be different. RTX 4090, LG C2 TV connected via HDMI 2.1. 4k120hz signal shows up only randomly. Problem's only on Linux but on both Wayland and X11. I have tried unplugging eARC soundbar, turning off VRR, no difference. 4k60Hz works always, but nothing above it consistenly. I did also try changing HDMI 2.1 cable.
Samsung LS28AG700N as secondary monitor works regardless using Displayport (4k144hz IPS), but I did try using just C2. C2 would lose VRR support if active DP adapter were to be used.
I would blame TV itself if it didn't work just fine on Windows.
Tried drivers from 525 to latest 535. No difference.
I know this is open source driver repo but something like this goes hand in hand with proprietary driver, right? I did only try proprietary driver.
EDIT: I think turning on new nvidia-modeset.hdmi_deepcolor=1 on 545 beta driver fixed my issue for good
This issue still happens with driver 550.90.07. All monitors and Samsung 4K 120Hz tv cuts signal after logging into Plasma 6.1 Wayland and 6.9.6-arch1-1. Unplugging the hdmi to the TV all of a sudden brings signal back to the other two monitors. What is weird, I didn't have this issue for a couple weeks but then all of a sudden after updating to KDE Plasma 6.1 and rebooting, this happened again.

Nvidia drivers installed from arch linux repositories:
Incidentally, 8K 60 Hz and 4K 120 Hz are both working fine in Windows (it is a dual boot machine).
Prior to upgrading nvidia drivers, 8K 30 Hz and 4K 120 Hz were working fine in Linux with the previous version (525.89.02).
