I revealed a small problem with the monitor 27 "Lenovo ThinkVision S27Q-10 [61E8GAT1EU].
The problem is that on a dark background in the upper right half of the monitor (a little right of the middle), a red stain was noticeable in the shape of a crescent (the photos attached to handling). There is no light background of this stain.
I tried to "shake" pixels using JScreenFix Pixel Repair (instead of 10 minutes the test lasted 5 minutes), but it did not give anything completely no effect.
Overheating in any part of the monitor I did not notice, the mechanical impact on the screen did not turn out, the sources of superal electromagnetic radiation nearby too.
Can audio speakers influence this? Or maybe the problem with the output of the image can then be to blame the video card (i have no built-in GPU).
It is possible that this is a IPS defect, but these are just my guesses.
Can I try to eliminate the problem remotely, or will I need to appeal to the service?
I completely disconnected the monitor from the network overnight, changed the settings, reset to the factory settings - no effect.
