I just bought a new Acer monitor and set it up, but there appears to be a patch on the screen that displays a purple smudge. Pic attached.


Edit: not sure if the pic did attach so here's an alternative:





White background works fine.

Black causes the smudge to appear.

Semi-noticeable on green/blue backgrounds.

Not noticeable on red or yellow backgrounds.


I've tried:


Restarting the computer (worth a try)

Wiping the screen

Reinstalling graphics driver

Running JScreenFix for 10 mins




Are the pixels just stuck/hot pixels?


Is there a chance this will fix itself if I leave the screen running for a while?


I googled around and didn't find anything like this. Hoping I don't have to send it back, it's otherwise a great screen.


Thanks for any help.

I have yet to see a monitor of any type "spontaneously heal" when behavior like this appears.


Since it's brand new it should go right back to wherever it was purchased from for a refund or exchange.

The LCD panel is actually damaged from what looks to be a bang where the magenta smudge is and you need to get it replaced!  It won't heal itself.

that's an effect they will call MIRA it's where one panel will touch another layer incorrectly, usually only happens on larger monitors/tv.  but it can happen on smaller ones.   take it back and get a replacement. it can't be fixed.
