Windows 7: Dual Monitors detected as one.

12 Nov 2015   #1

Windows 7 Home Premium 64bit
Dual Monitors detected as one.

I have two monitors plugged in, they both work fine. But they're both identified and detected as one monitor, so the same display is shown on both: Whatever I do on the left Monitor shows up on the right monitor. What can I do to fix this?

Sounds like it's set to duplicate. Press Windows key and P, then select extend.
