HDMI connected Samsung Monitor says “Not Optimum Mode, Recommended Mode 1920×1080 60 hz”

display

Every time the monitor goes to sleep (10minutes setting in OS) and during the boot I have a notification in the middle of the screen with the error message I wrote in the title. I can understand that during reboot the resolution isn't optimal, but how come the monitor think's the resolution is wrong when the OS shuts down the displays due inactivity? It's pretty darn annoying!

Does anyone know any tricks to get rid of the popup? Btw, I don't get the message with a DVI cable, but with my current 3 monitor setup I need to have said monitor connected with an HDMI cable as it's the only one of my three that has it, and there are only two DVI connectors in my GPU.

Hit the MENU button, and scroll down to the second from the bottom. Hit SOURCE to select it, the hit the down button until the options become AV mode and HDMI Black Level. Go to AV mode and hit Source to select it. Now press up or down to change the setting to OFF. Exit the menu. As long as AV mode is off, the monitor will display perfectly. If the color looks strange, change HDMI Black Level to Normal instead of the default LOW as well.
