Looks like LEDs are permanently on or shifted. So shadows are cast, and bright streaks stuck in place.
My guess is, it's broken. But, I thought it worth sharing the photo to see if I'm the only one, and whether it is truly knackered, or repairable.
Seems to have grown slowly over time. Just tried pixel refresh/screen burn clip @ 1080p. No improvement.
To be fair, I only notice when I'm watching things like planespotting streams (everything same brightness/colour/sky). When there's a lot of variation in colour and brightness (gaming streams) I forget it's there.
The photo is a plain white screen, 1080p, from the screenburn test video.
