For the 30 days that you are waiting to get the video wall controller fixed, would the financial investment of a hoard of new AMD Eyefinity 6 compatible cards be worth it?
Instead it may very well be worth checking the features supported by the Samsung UE 46" displays as these are professional displays that likely support video wall mode.
You have not provided the exact full model number, however (
according to the manual) the UE46A has support for video daisy-chaining via DVI input and DVI output (pages 25-26), and also supports video wall mode (page 152).
As such you could achieve dual 3x3 video walls using all the existing hardware you have already with near zero additional costs, assuming you have DVI cables spare.
Simply take 1 DVI feed from the pc and pass it to the first group of monitors, connecting the pc to monitor 1, then from monitor 1 use DVI loop out into monitor 2, repeat to monitor 9, then repeat again for the 2nd group of 3x3 monitors.
This way you have each group of monitors as a separate output from the PC, giving you flexibility to have different images on each group in extended mode or the same image on both groups using duplicated output mode.
As such this can be achieved without the use of any Eyefinity.
You could of cause loop out of monitor 9 from group 1 into monitor 1 in group 2 if you have only a single output from your laptop or dvd player device.
You should now be getting the same 1920x1080 image on all 18 monitors, once confirmed you can then put the monitors into "video wall" mode, and in doing so, you can setup the number of monitors in the group (up to 100 supported according to the manual - page 153) in a 3x3 configuration and then set the monitors relative position in this group.
This will use the monitors built in image up-scaling hardware to cut out a segment of the incoming 1920x1080 image and scale it up to fill the screen.
The up-scaling is essentially what the video controller is doing for you, however these monitors have such a feature built into them.
