I'm trying to extend the desktop across 10 Vizio 60" E600i-B3 TV's. I have Two AMD Radeon HD7870 Graphic Cards. All TV's are connecting via HDMI from the TV and converting to the DisplayPort connection on the cards.
I can unplug and plug these TV's in and I had 7 extended at once, but it seems random. I can unplug and plug and get a combination of 3 or 4 typically.
I updated the drivers for the Graphic Cards. Running Windows 8 Pro. 16GB of memory
Any help would be greatly appreciated. Thank you!
