Hey folks,
Having a weird problem with some system modifications. I'm using 2x AMD Radeon 7850s in Crossfire and trying to build a 6-headed monitor setup. I have Windows 10 detecting all 6 screens, but 2 screens get no output after windows boots. They will display the BIOS screen as well as the windows loading screen, but after that they are gone.
The system is linked to the monitors via 50 foot DVI cables. The cables all work and were used previously in other applications on this same PC(albeit with a different graphics card). Of the six screens, 3 are using DVI. One screen, which goes through an 8 port KVM works without issue. The VGA screens are also not having any problems.
Of the two problem monitors; one cable goes directly from the display port adapter on the card to a 4 port active DVI switch and then into the monitor. The other cable goes directly from the display port adapter to a 4 port active DVI KVM.
I have tried adding in DVI Range extenders on either(and even both) side(s) of the cable with no effect - it just makes windows stop detecting the screen. I've also tried using an active(powered by USB) Display Port to DVI adapter as well as the inactive one provided with the card(the documentation claimed ports 1-3 did not require active adapters).
Does anyone have any suggestions?
