I've been using an X900F tv (VA panel) as my PC monitor for a year now and although it has extremely mild IR, it did develop some extremely persistent IR or possibly burn-in from the windows taskbar (a static image displayed for 3000 hours straight). Two months ago I noticed the windows icon was slightly visible in the corner on grey backgrounds, and it's still visible to this day.
I also used a Sony X800D (2016) tv as a PC monitor for 1.5 years and it also had mild IR but it never got burn-in. It's hard to tell which monitor will get more IR then another since it varies from panel to panel (panel lottery) and from model to model.

I worked in the power generation industry and some of the IPS monitors we use to show control systems get the static images of the controls burned into them and need to be replaced every 10-14 years.
Its really bad when an alarm for fire shows green (no fire) for 10 years, then when it switches to red (fire) it still looks 80% green......
I will also say that what happens more frequently is the layers in front of the IPS pixels discolors. Think like what happens with old beige pc cases being yellow after 10-20 years of sun exposure. The transparent diffusion/and image sharpening and whatever else they use as layers in front of the pixels can discolor due to sun or even the LED light shining through them.
Well like mentioned this is a fairly "new" panel, at least as far as normal life expectancy on LCDs are concerned so that isn't the issue. It's also not something that happens after 1000 hours of a static image but rather 5 minutes.
I contacted LG support and they mentioned it can happen if a panel has been on for a very long time (this panel had been on for about a week when I noticed it and I do consider that long as far as my time perspective goes) and adviced me to turn the panel off and unplug the power connctor over the night and see if that fixed the issue.
Well it didn't, and after a couple of minutes of use it has some substantial image retention.
so just to sum up what this means as far as this particular panel is concerned;
- It's about 3 years old at this point so it's not that old
- It normally gets turned off after use every day, and the computer with it. Though recently it has seen longer prolonged use (upwards of a week of continuus on time).
- The image retention can most easily be seen by moving icons around on the start line, though any static image that gets moved will show the same result.
- The monitor did absolutely NOT have this when new, and the review on rtings.com sugests that this isnt' something that is present on the panel when new either (https://www.rtings.com/monitor/reviews/lg/27ud58-b
- 10-15 minutes of an anti burn-in/image retention video from youtube seems to make the retained image go away, but it's back within 5 minutes when a static image is present.
At this point I'm just going to report back to LG and see if I can start the RMA process.
