Hello, this is my first time using Eyefinity, and it has been rather frustrating. This is my setup:

 

2x Radeon 7850 (DVI, HDMI, mDP, mDP)

4 x 39" FUllHD HDTVs.

Windows 8 x64

Newest AMD Drivers (12.08)

 

I tried using the following:

DVI to HDMI

HDMI

mDP to DVI (active) then DVI to HDMI cable

mDP to DVI (active) then DVI to HDMI cable

 

And also

 

DVI to HDMI

HDMI

mDP to VGA (active) then VGA cable

mDP to VGA (active) then VGA cable

*I had more problems with the mDP -> VGA
 
Catalyst Control Center detects all HDTVs without problems, they all work great in extended mode, but when I create the Eyefinity Group, 2 of the 4 TVs are not using all the visible area(black bars on every border), while the other 2 TVs look great. All HDTVs have the same resolution and are from the same brand. All the HDTVs said that the resolution been used is 1080p. I changed the resolution at the Eyefinity section to a lower option, (2 TVs said that it was 1680x1050) and only 2 TVs worked, 2 of them showed a No Signal message.
Hope anyone can help me with this, because I feel like I reached a dead end.
Thank you in advance for your time.

Don't know if this might be of help, but I just find out that the resolution seems to be different on the mDP->HDMI monitors than the ones in the HDMI and DVI ports.

mDP->HDMI = 1080P (it takes all the visible area)

DVI -> HDMI = 1680x1050 (when I use the 1080p, the visible area is smaller)

HDMI = 1680x1050 (same as above).

I changed the monitors from one output to another just to verify that the problem is not the TV or the cable, and the "error" goes to the new TV, so it seems that the problem its with both DVI and HDMI ouptuts both mDP are working well.
