Hello Mighty Blur Busters!
Would it be terrible to ask for a bit of help straight off the bat? I'll be making another post in a little while about a bug I found while registering with this forum, hopefully that helps balance the karma - that bug might be stopping others from registering
- or is that the secret test for gaining entrance to these esteemed halls of screen knowledge 
You probably think this is a bit lengthy, here's the TL;DR
TL;DR
My ViewSonic XG321UG monitor seems to have a faulty pixel inversion algorithm, leading to rapid image retention and no flickering on inversion tests. Despite resets and adjustments, the issue persists. If the inversion algorithm isn’t working, could continued use with static images risk long-term screen damage?
Full Post (it's rather length)
Recently, I discovered some odd behaviours with my ViewSonic XG321UG LCD monitor and suspect that it has a faulty or non-functioning pixel inversion algorithm.
The first odd behaviour is the unusually quick image retention on static elements. To reproduce this, I displayed a fullscreen black and white checkerboard image for 5 minutes from the ScreenburnIn site using the "screen-image-retention-test" pattern. Afterwards, I quickly switched to a fullscreen gray image and took a photo of the result:

To further investigate and confirm my monitor's inversion algorithm functionality, I went to a pixel inversion test website (https[:]//pixelinversion[.]com/) and observed each coloured images while stationary.
As I suspected, none of the coloured images flickered. Only a couple of them showed slight colour alterations (cross-talk?) when they're moved towards the area on my screen where it did not have any image retentions from the checkerboard test.
Worryingly, this seems to indicate that the rest of my screen has a faulty/non-functioning inversion algorithm. A full power-cycle, factory reset and changing of G-Sync and scaling mode was performed, but unfortunately, the test results remain the same.
If I continue to use my monitor in this state, will my screen deteriorate over time? This assumes that the inversion algorithm is not working and I display some static elements 4-5 hours each day.
Thanks for reading to the end! What do you think?
