I need to build a 6-monitor workstation for a surveillance video system, and would like to do it using an ASUS P8H77-M mobo, which is easily available in my country, and a Core i7 2600K or above, to use its hardware decoding with Lucid Virtu.
I have tried to do this several times, but always when I put one graphics card automatically it disables IGD, and I can not find a setting in the mobo UEFI to keep both graphical devices working.
Look in BIos, Advanced Menu, chipset, for 2 options:
- Surround view: Make sure it's "enabled" (I think auto will disable the IGP when you put another GPU)
- Primary video controller: select which GPU will be active at boot (note: windows manages the display itself, so this if just for BIOS).
