Hello, I had a dual monitor setup going for about a month and then it just pooped and my first monitor didnt have its native resolution.

It changed into 1024x768 ( native ) instead of 1440x900 ( native ), and didnt show 1440x900 as a resolution in windows's resolutions.

I tried forcing it with Nvidia's Control Panel and setting a non-supported 1440x900 but it just made it into a square and had black bars on the sides.

Its connected with a DVI-VGA adapter and lets me have resolutions up to 2560x1600 for some reason.

When plugged in with a HDMI-VGA adpater it lets me have 1440x900 but goes black every 1-3 seconds and teleports my cursor to the middle of the screen.

When the second monitor is plugged in via HDMI-VGA adapter it works perfectly, when with DVI-VGA it doesnt even get any signals.

I tried swapping hte DVI-VGA adapter for an another one but it didnt help.

Please help!

First thought that came to mind was a W10 download of an "upgraded" driver, several months ago after updating to W10 1511, after a reboot my display was at 800x600 and nothing else was available. Once I figured out it was a driver downloaded along with the W10 update, I reinstalled the previous driver and rebooted. Things came back up the way they were before, 1600x900.

You might check if you've had an updated video driver(s) recently, that'd be the easiest thing, roll back to the previous driver and your settings come back. Other than that I'm not too sure what might be a fix.

Im pretty sure that its not the drivers, i used DDU to uninstall them, then i installed and did it like twice with drivers that nvidia tech support gave me.

Did you perform a clean install of the nVidia drivers?  This is most likely a driver issue.
