So recently, my S2440L has been going into a PSM randomly throughout the day, usually while gaming. My computer and sound remain on so I don't believe that this is an issue with my computer. It is usually fixed by a quick reboot of my computer, and although it works, it is quite annoying to have to reboot my computer multiple times throughout the day because my monitor won't detect a signal. I don't know if it matters, but I am connected by HDMI.
"So recently, my S2440L has been going into a PSM randomly" * What driver, software, or hardware changes were made to the PC just prior to the 2012 S2440L PSM issue appearing? * What PC model? * What operating system? * What video card/GPU? * What video out ports are on the video card/GPU? * Have you replicated the S2440L + HDMI to HDMI cable issue when testing on a different PC? * Have tested using the S2440L + VGA to VGA cable on that PC?
