I've got a 19" ViewSonic here and also had the "Resolution" nag problem.. You'll need to use the buttons that are on the monitor to fix this.. Not the keyboard but the actual buttons that are on the monitor casing.. ON this monitor, press button number 1,(on the left) brings up a menu with options. Use the down arrow button (number 3 or 4) to select the "Setup Menu" selection.. Then use the down arrow button again to navigate to the "Resolution Notice" selection. Use the number 2 button to select it. Use the up or down arrow to select OFF, then press button number 2 to select that option. Press the number 1 button twice to then escape both screens, one at a time.
Hope this helps.
I Can't figure out how to stop my monitor from displaying the same mssg regarding best resolution. I like the resolution I have chosen. It's not the very clearest but it's large enough to see without my glasses.
You can't click the message window closed. You have to wait a few seconds for it to disappear each time and this is annoying me. It's a view sonic VA2226w.
