Question HDMI ARC input causes conflict with 3090 and/or Win11?

[Amused]

So I just got the Samsung G7 43 inch monitor. Running it at 4K 120 hz. (wanted OLED so bad but I leave web pages and documents up for hours at a time)
For the first few days I had the PC hooked up to the HDMI ARC input (HDMI 1).
I was getting random few second black outs on the screen during gaming. I tried 4 different HDMI 2.1 ultra cables.
On a lark I switched to the NON-ARC HDMI input (HDMI 2) and... problems seem to be gone.
I'm not seeing this as a known issue with HDMI ARC ports?
Am I missing something?

I'd probably want to use DP at 4k 120hz.

The monitor is capable of 144hz, but only with HDMI 2.1. It has DP 1.4. I was doing 120hz just until I could figure out what was going on.

OK, so I tried DP port and once asleep, the monitor will not wake up unless I reboot the display drivers? (WIN-CTRL-SFT-B)

WTF?

 

[Amused]

Anyone have any idea how to fix this?

What video card are you driving the monitor with?

 

[WelshBloke]

I'm not up on ARC but you probably don't need that for a monitor?

I should read titles.

I'm using display port now. It woke up with HDMI but had random brief blackouts during gaming. Even on the non-ARC HDMI port.
That problem is gone now that I've switched to display port, but NOW it won't wake up without resetting graphics drivers.

My card is EVGA GeForce RTX 3090 FTW3 24G-P5-3987-KR.

Thats sounding mor like a gxf driver problem. Youve done a wipe and restall of the graphics drivers?

I have. A clean install of the latest NVidia drivers.

Wait, did you do the video card BIOS update for DisplayPort? There's an errata and BIOS flash.

Yes, I even tried again and it said it was already applied.
