There is a 7% grey screen in part of my document but I can't see it. It prints fine, and the 7% is registering in Output Preview. "Display large images" is checked in Page Display. What could the problem be?
[Moved from the Lounge (which is where you can "connect with your peers" from across all of Adobe's products for conversations that don't directly relate to help and support) to a product-specific support forum - moderator]
What software are you using? You've posted in the non-support, all-of-Adobe forum Lounge. It's for people who use Acrobat, Photoshop, After Effects, InDesign, Experience Cloud, Document Cloud, Creative Cloud...etc. to hang out and chat about general things.
Let us know what you're using and a moderator can move this thread to the appropriate, product-specific, support forum.
Actually, I've sorted it out. The issue was caused by my monitor's contrast setting, which I had adjusted about a week ago and forgot about completely (face palm). My second monitor was OK, so I thought it was the program (which was acrobat pro dc).
Glad you figured it out!
