Hello, I have two W4100 graphic cards in Dell Precision 3620. I need to connect 6 x 4K monitor Dell P4317Q. I have 4 displays connected to first graphic card and other two to second graphic card. I was able to build two display group one at each card, but I need one over two graphic cards to function it as one big screen. Is it possible with this hardware ? Running Windows 10.
No, you cannot combine screens across 2 different GPU's into one Eyefinity group with the W4100.
However. You can use two W7100's with the S400 Sync Card to achieve what you are looking for.
