These may need changing. If you cannot find your exact monitor model then choose one of the Generic settings that matches the resolution you want. (btw the correct settings for a Dell M782 are Horizontal Sync: 30.0-85.0 Vertical Refresh: 50.0-160.0 ) once you've fixed this, go bask to the Settings tab and choose the res you want.
