Hello Folk, I left my pc for half on the desktop nothing else running, came back to the left side looking weird, so first I thought it was a graphics card issue and turned off my pc to turn it back on. also did the same for my monitor, noticed it happening even during the boot screen of my monitor, is this just simply image retention that will revert on it's own if left alone? it's the acer k242hqk ips lcd screen.
