Hello,

I have three monitors, all the same resolution, manufacturer, all that stuff. I have a 7870XT and an active adapter for the third screen, however, two of them turn on automatically on system start, but the third has to be replugged into my graphics card to activate. Is there a fix for this? Thanks!

it happens on start up/boot then shutdown midways?

that is how my 3ple screen works. when i boot 2 of them would turn on then after i finish booting the 3rd 1 would activate on its own.

no need to re plug the cables (for me)
 


Please provide us with some details about the displays, their connections, and the active adapter that you are using.

On boot, two start. The third, with the active display adapter, does not start. If I replug in the display adapter into the graphics card, it works.

I've tried booting all the way to desktop in which it is not detected even then by Windows or Catalyst
 




I'd put money on it being a crummy active adapter.

From what information I can find, all three of those displays support digital inputs.

Connect the first one via DVI, connect the second one via HDMI to DVI (passive), and connect the third one via DisplayPort to HDMI + passive HDMI to DVI cable.
