Question

Magenta infection in LR Classic and PS

I'm running the latest PS 23.11 and LR-Classic 11.2 on Windows 10.  On the same day both programs all of sudden have way too much magenta in EVERYTHING.  Even the histagram is magenta and not red.  It is not my monitor.  I checked using Corel Draw and everything there is perfectly fine.  Everything on the internet is fine.  I looked at my images that were posted on ViewBug and they are fine there.  Only PS and LR have this flaw.  Even if I use the color picker in PS it is also way too magenta.  I have shut off the PC and restarted.  It still has the issue.  I have attached 1 screen shot.  Those flowers are supposed to be red.

What happens if I uninstall/re-install both PS and LR Classic?  Will that fix this problem?

First, try disabling GPU in the preferences (Preformance tab). Any better?
If not, recalibrate and build a new ICC display profile, the old one might be corrupted.
If you are using software/hardware for this task, be sure the software is set to build a matrix not LUT profile, Version 2 not Version 4 profile.
If turning OFF GPU works, it's a GPU bug and you need to contact the manufacturer or find out if there's an updated driver for it.
