hi, I have another Solution and it WORKS perfectly on my PC here's what I did: 1. one day my viewsonic 22 inch square missing 1680x1080 , I don't know why , maybe because my brother's game. (I tried everything, update driver,powerstrip, reinstall VGA driver still doesn't work) I try to turn it OFF 2. I change my other monitor Dell 24 wide and replace viewsonic 22. Turn it ON. Right click on desktop>settings> Change my resolution to 1920 x 1080, turn it OFF 3. Replace again my monitor to viewsonic 22 inch square. And Walaaaa... my 1680x1080 back to normal.. I don't know what happen, but it WORKS !!!! sorry for my English, cheers from Indonesia
