How to use two monitors: one from video card one from motherboard

Question

I'm trying to get two monitors set up. One is plugged into my graphics card using an hdmi cord, the other is plugged into my motherboard using another hdmi cord.

Graphics card: NVIDIA GeForce GTX 770

Motherboard: ASUS Maximus VI Gene

Monitors: Del S2740L

OS: Windows 8.1

Only the monitor plugged into the graphics card is working. Windows cant detect the monitor plugged into the motherboard.

Is there anyway I can get this to work?

Solution

Apparently the iGPU Multi-Monitor setting under advanced/system agent configuration/graphics configuration needs to be turned on. This is labelled for being for virtu but is necessary for the integrated GPU to be detectable by windows, even if you arn't running virtu.

Obviously the location of this may vary with different motherboard brands and the name of the setting may be different.

My guess is since lucid logix uses both GPUs, it tells the motherboard to simply run both - independent of whether you're running more than one monitor (with lucid outputting what you're rendering on the dedicated GPU to the integrated GPU), or using a multi-monitor set up taking advantage of both the IGPU and Dedicated GPU as independant outputs without lucid.

This might changed with later boards - but it was made possible by on die GPUs not using up PCIe lanes, and newer version of windows playing nice with more than one video card driver at a time.

You most likely have "Internal Graphics" set to Auto in the bios, which means it will disable itself when it detects another graphics card. If you set it to Enabled, it should remain enabled when you have the other card installed.

Possible dupe of superuser.com/questions/523928/… - could you go into bios, turn on iGPu multi monitor and see if it works?

This is false. I'm got it working. See Paul and JournemanGeek's comments on the question.
