Faulty hdmi port?

[sgoaty]

I've got a Samsung G8 Oled G85SD I run multiple inputs to it, my gaming system, 1l mini PC and test bench/whatever system I'm messing with. I've had problems getting the hdmi 2 to display anything for a while now so did some messing around today and I'm starting to think it's a fault with the monitor.

So far I've changed out the cable and tried it in a 5090, 2070 super and 1080ti.

Swapped the cable from my mini pc from hdmi 1 to hdmi 2.

Anything else I should try or is it a warranty issue?
Thanks
Scott

You could try the Power Cycle Procedure.

1 - Turn off monitor and PC
2 - Unplug both devices
3 - Wait 30-60 seconds
4 - Plug back in
5 - Turn on monitor first, then the PC

If this does not work, it looks like you have tried all you can so RMA time.

I had a Samsung G7 32" 4K screen that bad at initializing when my PC started started, was a pain getting into the BIOS. I found turning the computer and monitor on at the same time helped get around it.
Worth checking for firmware updates for the screen too just in case.

I did everything suggested and it was still the same so I started an RMA request. I was asked to send a video of the fault and while trying to film it it was working and has remained working ever since. I've still got a year on the warranty so I'll be keeping a close eye.
