Right Here Right Now
I have a bit of a fun one here. I'm leaning towards the monitor since it's the only component I haven't replaced but want outside opinions since I like this monitor and don't want to be down a monitor for a month while RMAing it.

On my desktop I have two monitors - an Acer XB271HU and a LG 27UK67. I use the Acer as my primary, I'll admit my eyesight is shot and prefer the high hz over high rez. So that's the Acer for web browsing, gaming, word editing, 90% of my shenanigans. The LG I do movies, web streams, as my multimedia screen. For an IPS panel, it's overall color reproduction is in a league above. (LG simp)

Now starting 2-3 months ago, I ran into an issue with the LG. It's worth noting, it started just about the time I decided to use my little offbrand portable monitor as a third monitor on my desktop. And it being powered and fed video data off the same USB-C cable, and my 2080 having a USB-C out, I just went that route. Worked fine, for a bit. '

Then, in order to save a few bucks I started shutting down my desktop at night. And this is when I noticed the problem.

When I power it on in the morning, for the most part it seems fine. But after a few minutes I'll load up FF, get a Twitch stream going on the LG, and with in I'd say 1-3 seconds of the page and video stream loading, the screen starts flickering - maybe half a second on, 3 seconds off. And it does this until I power off the LG for 5-10 seconds and power it back on. Sometimes it takes multiple cycles, and it always starts right after the Twitch stream starts.

First thing I did, take off the offbrand monitor, check the cabling between the GPU and LG. Everything looked good. Reseated connections, everything is solid.

Re-installed display drivers, also fine.

Disconnected DP cable, let the LG sit at it's idle screen, fine.

My final thought was maybe the eBay special did something to the 2080 as it only started AFTER plugging it in. But just an hour ago I finished installing a 5070, reinstalled drivers, booted things up, and it happened again.

Any ideas? As I'm writing this I'm wondering if Twitch uses a form of HDCP and there's something "went off the deep end" with the LG in the past couple months as the only link I can see. May play with that, but other ideas are appreciated.
 
Update -

Not 100% sure what happened. This may be due to *another* clean driver install. Maybe the DP cable being just ever so loose? It's non-locking. But I haven't run into this exact issue since that first weekend after the new card install.

The issue has been greatly reduced, but still present in a form. Maybe once a day the LG will go blank for 3-5 seconds, then recover, and be fine. It is no longer a real "issue" for me but a curiosity at this point, so I'm leaving the thread open for input.
