Second Monitor not displaying max resolution

[Connor West]

I recently plugged my old monitor into my new pc to use as a second monitor and the native resolution is 1440x900.

I ran it at that for about a year in my old pc but i got a new pc and monitor and now it will only display ay 1152x864

My main display is at 1080p from hdmi and thi second is dvi, my drivers are up to date and i have uninstalled and reinstalled them so it isnt that

anyone got any suggestions, thanks
