Can anyone help? I have a iiyama Prolite B2403WSB1 monitor. Last week I had a virus and needed to reinstall my OS and software. Suddenly the colours look odd on the monitor. It looks like there is a pink going to green wash over it from top to bottom. I uninstalled the last software I'd put on (Adobe Photoshop CS) and the monitor was back to normal. I then installed the following and the problem came back: Memory map OS Memory map navigator Eraser Quicktime WriteitNow 4 None of these have ever caused a problem before but I uninstalled on the off chance one of them was causing the colour issue. They obviously weren't because I still have the problem. I could ask iiyama but my monitor is out of warranty. Do you know what could be happening?
