My system uses 3 Asus 144hz monitors in SLI config. DVI cables for each monitor. 2 on the 1st card, and one on the second card.

I then also plug in a 60hz Acer monitor into card #1's HDMI slot - and if I do this after windows boots, everything is just peachy. No problems, no issues.

However, If I go to restart the system, or start it cold, the system starts up, the center of the 3 monitors lights up, the 4th monitor get's the windows "boot" image and all is normal.

However, when it reaches that point when normally I have the windows 8.1 login screen with, all screens go dark except for the center of the 3 monitors, and it displays my default background color (orange in my case) - and I can't click or see a mouse, login screen or anything else.

After 15-20 seconds, that screen goes dark, and then lights back up with a black background.

I then have to unplug the 4th monitor, hit the reset button, boot the system (all is normal), login to windows, and then manually plug in the 4th monitor, and like I said above, all is peachy!

Any ideas why the 4 monitor setup won't boot properly?

System Specs:
windows 8.1
MSI X79A-GD45 Plus
64GB Ram
2 SSD's (one for boot, one for games)
2 1TB+ HD's for other storage of non speed essential data.
2 780 TI EVGA video cards
1 CD Rom Drive
1050 Watt Power Supply
Acer H243H Monitor (HDI Cable)
3 Asus VG248QE monitors (DVI Cables)

Anyone else seen this issue?

Thank you,
Kevin

Basically because when you run SLI, nvidia for some reason does not allow those ports to function.
Not sure exactly why/how that is - but that's the way the system indicates the ports can be used.

Already done. System boots just fine with the 4th monitor unplugged. In fact the "solution" right now is to do just that, and then plug the monitor in after I log into windows 8.1

What I'd really like to do is figure out how to not have to plug and unplug the HDMI cable out and in each time I want to reboot. Not sure if anyone else has seen this problem or not.
