desktop resolution and active signal resolution

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.

 

Active signal resolution wrong

I have a 1080p resolution monitor, and I changed the desktop resolution to 1600 X 900 due to my laptop being also 1600 x 900, but when I change desktop resolution, the active signal resolution is different, and stays at 1080p, and is causing issues. I have tried list all modes in the graphics settings, but when I changed it nothing happened, just the desktop resolution changed. I need to change this. Please help.
