“I'm running Windows 7 on a desktop PC with an 27" AOC monitor. When I run the wmic command to determine the model of my monitor, all values return as "Generic Non-PnP Monitor". This is consistent with how the monitor is displayed in both Device Manager and Screen Resolution. What should I do?” - Quoted from Forum
