Hi. I have HD 5450 installed. I used 2 displays connected to VGA and DVI ports for a long time. It vas OK. But I desided to connect the third one.

Specification of 5450 says:
ATI Eyefinity multi-display technology17,1

  • Three independent display controllers
    • Drive up to three displays simultaneously with independent resolutions, refresh rates, color controls, and video overlays

So I connected the new display to HDMI port and realised that adapter can feel all the displays, but one (no matter that one is) have to be disabled.

If #2 and #3 enabled - the #1 is disabled in Control Center. Than I try to enable #1 - Control Center make me choose #2 or #3 to disable.

What I do wrong?

The Radeon HD5450 you have will only support a maximum of 2 monitors.

In order for AMD Graphics Card to support 3 or more monitors, the card must have a Displayport output.
