rx580 Is this my gpu going bad?

[Chiakuu]

I appear to have a recurring issue with my graphics card. Sometimes, especially if I hot unplug-replug, my monitor becomes dim and washed out - but not the whole monitor. I cannot really capture it on camera - most of the monitor window itself dropped brightness and contrast drastically, but my cursor is still as bright white as day! The only way so far I can hopefully fix it is by restarting the entire machine (sometimes that doesn’t work the first time). The picture attached is the closest to showing the extent of what happens as I can get - the cursor is above the normally blinding white google homepage, and even that doesn’t show the extent of the difference in contrast. 
 

Today’s hotplug trigger was when I switched back to my desktop’s monitor input, the screen was a solid green - replugged and voila welcome to dimland, population everything but the cursor.

 

I am debating on massively upgrading my rig in October-November, but I don’t want to be forced into it by my gpu (already has some issues, like keeping cool) getting worse.

Which sort of cable do you use? (DVI, HDMI, DP, ...)

Have you tried reinstalling the graphics card drivers?

Does the same problem occur with a different monitor or only this one?

 

My guess is, that this is either a cable, port or monitor issue and not a GPU issue.

This is over HDMI - I believe this issue started before I reset my pc, so I have reinstalled the graphics drivers since then; and I only have this monitor to test with as my secondary is VGA. I actually have quite the nice cable set up imo - I was able to snag a nicer-than-generic HDMI cable from the household supply before they all evaporated. Of course that doesn't excuse that its the cable going bad, but I believe its a newer cable from December 2019 that came with my switch and worked fine with the television. This monitor has no issues with any other device as well - it works fine with my mini and my switch, without any sign of these issues.

I know this topic went stale, but it happened again. My audio throrugh my monitor keeps getting corrupted until I restart, so I hotplugged to try and get windows to reset it - sound is gone and the monitor is dimland again. If it isn't the gpu, windows has been irritating me more and more recently - would appreciate some advice.
