Hello , I have a Dell Optiplex 3020 , Win10 Home and an LG 32in monitor . During start up I get a pop up box saying not set at optimal resolution . My pc does not support what it says is optimal resolution but the display looks great . I have done the right click desktop , graphic options, balloon notifications , and disabled optimal resolutions notifications . Under settings , system , notifications , get notifications is turned off . all notifications is off . The popup box has a button that says don't show this message again but when I try to mouse over it the curser disappears . Any ideas how to stop this box from popping up ?? it stays there covering the box for my pin # for about 2 mins !! Thank you !!
