Not optimal display setting error leads to crash & reboot.


I am experiencing the error "Not optimal display settings, please use 1920x1080" as on OSD popup on my monitor with everything else going blank. I am using this exact resolution at 120hz as native on my monitor. This occurs while gaming, while using basic applications, as well as while sitting idle at desktop.

Of the very few similar mentions of this issue the pre-action is to power cycle the monitor via un-plug/re-plug or power button on/off. This worked for a while for me only now when I do either my PC freezes and will either stay frozen until manual reboot or sometimes reboots on its own after a few moments.

I have just performed a complete re-install of Win7, fully updating it, and installing the latest drivers from NVidia. Problem still persists.

I would prefer not to have to warranty this monitor as we all know what I would receive would be a used reconditioned unit likely to have the same problem. I can live with the error message as long as cycling the monitors power does not crash my system.

As always your assistance is appreciated.

  2. I'm also experiencing a crash that may be related but with slightly different symptoms. While playing World of Warcraft my screen will occasionally go black for a few moments and then either return to normal or crash and reboot.
