There's more than the width and height but also the refresh rates. Sorry, no, I have no fix but do know about it and since PCs are all over the map on controls for this, I can't be specific.
Tell more about the connection and rates.
I have a monitor that says I need to change the resolution to the recommend one every time I get on the computer, the thing is I have it set to that resolution already. It gives me an option to "not show this message again" but it wont even let me click on the message. Does anyone have a fix for this?
