3 r290x cards and 4 displays?

I have 3 Radeon 290x cards connected together (Crossfire...?) Is it possible to connect a total of 4 displays (3 LCD monitors, and 1 HDTV)?


My card connections are as follows:

HDMI = TV via HDMI (Identifies as "Display 1") - shows up as detected, but cannot be enabled.

DisplayPort = RIGHT monitor via DVI-to-DP Adapter (Identifies as "Display 4")

DVI 1 (top) = CENTER monitor via DVI (Identifies as "Display 3")

DVI 2 (bottom) = LEFT monitor via DVI (Identifies as "Display 2")


My 3 main monitors work just fine, with the desktop extended onto all 3 (no EyeFinity in use). My TV, which is mounted on the wall above where my monitors sit, will not connect, althought it is physically connected to the HDMI port of the top most card (where all the other displays are plugged into). In the Windows 10 app, when I try to enable it, I get the error: "The display setting could not be changed. Please try a different combination of display settings.


I also have tried plugging the TV into some of the other ports on the remaining cards, with no luck (HDMI-to-HDMI, as well as HDMI-to-DP). It doesn't even show up in the windows display applet when I try it this way.


I'm using Windows 10 x64 pro, with everything up to date, and did an update to the latest Radeon drivers. Any thoughts? Some screenshots attached.
