So I had this problem before... I bought the Monitor through Amazon so I got it replaced ASAP with another brand new one and the problem is back again? The exact same problem I had on the monitor I returned.
Problem: There is a very clear glow(?) and it gets worse and worse from:
Bottom Left->Bottom Right & Top Right->Bottom Right
I also noticed the problem happens to be in the spot on the monitor thats the hottest(does feel quite hot to the touch, this is the side where the power is plugged in). It seems like maybe theres an overheating issue... I'm pretty sure the Monitor was perfect for a while and then it just decided to do this again??? I highly doubt they did but maybe the monitor just overheats and damages the panel....?
The monitor is the Benq XL2730 and seeing as I'm having the EXACT same problem I had hoped I'd have been able to find similar problems but I cant find a single person with the same issue? so not sure if I'm missing something but I seem to be the only person with the problem and it happened twice in a row. HELP!!?? q~q
