I have an ASUS Maximus V Extreme motherboard which has onboard video. There is an Asus GeForce GTX 670 in PCIe slot 1.
In the BIOS, I have PCIe
selected as the preferred GPU. I've tried disabling Fast Boot and other items to attempt to get the PCIe display to work during POST. I've also updated the BIOS to the latest version available on ASUS' support site.
With the HDMI display plugged into the onboard video, I can see the POST and everything is fine. With the HDMI display plugged into the PCIe GPU, I have a blank screen until the point in which Windows starts to initialize and then everything is fine.
Is there a setting somewhere that I'm missing?
The problem is, I dual boot to Ubuntu and I'm forced to manually switch the HDMI cable to select things during POST or to enter BIOS. Not very convenient.
Any help would be greatly appreciated.
I would love to but I can't seem to find a way to fully disable the onboard video card in the BIOS. – Travis Vocino – 2014-03-21T02:04:16.283
The only option I can find in the manual that might disable it is the iGPU Multi-Monitor option (chapter 3 page 29). – MaQleod – 2014-03-21T02:31:34.047
What happens when you try booting it with no cable connected to the motherboard. Just the PCIe card connected? Also try disabling "Lucid Virtu" See this Asus support thread: http://rog.asus.com/forum/showthread.php?21849-Disable-onboard-video-Maximus-V-Formula

@BryanC. I only use one display and it is only connected to the PCIe GPU. Under those conditions I do not see POST or BIOS and only get a display when Windows gets initialized. Oddly, the card IS detected by the BIOS and listed in the PCI list. – Travis Vocino – 2014-03-22T02:03:44.360
1@TravisVocino Ok, I did some more digging. I've found some info in the ASUS forums that indicates that that you may actually not be able to completely disable that adapter but I also find discussions on where you can. :( --- You might want to go to Asus tech support for further information though as I find it surprising that this could really be the case. Sorry I couldn't help more on this. Can you post the exact model number of your board and I'd be glad to pull down the tech manual to see if there's anything in it. – Bryan C. – 2014-03-23T00:21:20.290
