I have my desktop resolution set at 1280 x 1024, which is what I want,

but the active signal resolution is set at 1920 x 1080.

Where can I change the active signal resolution to 1280 x 1024?

I have tried going to "display adapter properties" and list all modes,

but this only lets me change the desktop resolution.

Hi MayonAccounting,

it is normal if you change from the recommended resolution.

Typically, your desktop resolution and your active signal resolution will be identical. To provide a smoother experience, Windows prefers to keep your display running at its native signal resolution. If you change your display resolution under Settings > System
> Display > Scale and layout > Resolution, you may see a difference between your desktop resolution and your active signal resolution.

is there a problem with what you see on the monitor?
