The display is 3 you said that the best resolution is 1680*1050 but I can not find it in the setting of 1680*1050.
That's what the graphics card doesn't support. The computer system defaults to just showing the resolution of the graphics cards you want to see,Desktop right-click - properties - Settings - Advanced adapters - listing all modes is OK
The 16:10 is usually 1680*105016:9 is generally 1920*1080
Generally 22 inch display ratio is 16:10 and 16:9 two proportions, relatively speaking, the proportion of 16:10 more, 16:10 resolution includes 1440 x 9001680 x 10501920 x 1600. All users can find one of these three on the tuning resolution. Of course, the general set of 1680 x 1050 is the best effect. If the resolution is 16:9, then the optimum resolution is 1680 * 945.
