So I have three monitors:
- One with a HDMI monitor (my "main" one)
- One with VGA
- One with the white (and somewhat larger) VGA looking cable
I have the AMD RADEON HD 6450. This has eyefinity, which supports up to four monitors.
If I plug in more than one monitor, it disconnects the other non-main one. In the catalyst control center, if I click "Extend" on the non-working monitor, I get an error:
To extend the desktop, a desktop or display must be disabled.
With the options "Continue" or "Cancel". Both do what you could probably imagine. How do I use three monitors?
