Hi I've been trying to find info online to sort this out but can't seem to find anything. I have had slight static showing in my displays on my freshly built PC with vanilla Arch installed. This would only really happen during my mobos splash screen, and would stop as soon as my OS began to load. Now I've been customizing my arch for a few days and had no issues thus far, even have ran a game in the background (RuneScape) with no visual issues.

Today I started moving my Minecraft server to this PC and installed docker as well as Crafty Controller (may or may not be related) and my display is getting significantly worse static, and even shutting off. If I wait long enough it comes back eventually.. not sure what to troubleshoot further. I have AMDGPU, mesa, and vulkan-radeon installed. Here's a video clip of what's happening. Would greatly appreciate any advice.

HDMI? Check the cable, give it a wiggle, try a different one, make sure it's not nearby any power or data lines

hm I've not seen this sorta thing with DP myself, more with HDMI which is why I mentioned

#

Your video is pretty classic crappy video signal though, to my eye

#

i.e I don't think it's your PC itself

I'm not sure why that would be happening. I had these exact monitors hooked up to my other PC, actually didn't move them at all just unplugged the old one

#

Let me try hooking up my 2nd monitor

That was going to be my next suggestion - try other machines, other monitors, other cables

#

Yano, rule out hardware

#

Does your monitor have an info thing? It might say what signal it's expecting/getting

#

hmmm it may just be that cable im not sure

#

what did you mean by the info thing?

#

I picked show info and it has a little info on it, not much

#

#

well I had unplugged and replugged the monitor in a bunch from the pc side, decided to unplug replug from the monitor side, after your comment of thinking it's just the signal. It's back up now, time will tell if it decides it doesn't wanna keep working.

#

so it's fixed (for now) will report back if it cuts out again, thanks @winged sphinx for the 2nd set of eyes
