Hi guys, I've decided that I would buy a Dell2408wfp monitor with 30-35ms input lag(at native resolution?). But when I do more reading somehow I get this idea that input lag increases when resolution is scaled further from the native resolution of the monitor. Is this true? And, is it possible to play games on 1680x1050 resolution on a 24" without image distortion(exactly like a 22" monitor if I use 1:1 pixel mapping) or will it encounter any other problems ? Please help guys..

Generally it is true that when using less than native resolution there will be increased input lag because the monitor or video card (if you select this option in the card's control panel) must interpolate how best to fit each frame on the screen.

1:1 pixel will allow you to use exactly the number of pixels. 1680 x 1050 will be centered on a 1920 x 1200 monitor and the unused pixels will be black.

In case you did not know, every 16.67ms of lag is 1 frame of lag.

That is based on the human being capable of seeing 60FPS. 1 second has 1000ms, so 1000ms/60 = 16.67ms
