    ThinkPad T61/T61p with discrete nvidia graphics card and WSXGA+ (1680x1050) built-in LCDs.

    Using the laptop alone I wouldn't dare change from the native resolution... the basic situation here is using it in an advanced mini dock side-by-side with a 19" external LCD running 1280x1024. The difference in display sizes and resolutions creates the skewed image effect of things getting bigger and smaller moving across screens. To "normalize" the images a custom resolution (1126x712) can be set on the laptop screen so the laptop LCD will render the same as the 0.294 dot pitch of the external LCD.

    Is it a bad idea to run the laptop LCD in a non-standard resolution like that? There is (of course) warning against using monitor modes not reported by the LCD, etc, but what is the real risk?

    If changing only the resolution and not the refresh and sync rates does the graphics card just convert/resize the image and then output the "distorted" image in the native resolution to the LCD (like an upconverting DVD player) or does it completely pass it off to the LCD in the different resolution to do the rendering?

    Any technical detail would be greatly appreciated. Thanks.
