I tried this- it didn't help, but thank you so much for the suggestion!
I tried the HP X27i recommended by Aquila, but unfortunately it did NOT work for me- I could tell within 10 seconds it was causing that burning sensation in my retinas! I did play around with all the settings- it's a great monitor and I could get the color very stable looking. But after playing around for only 10 minutes I was relieved to put it back in the box.
