Got a weird issue here that I am completely stumped on.
I recently picked up a new ASUS PG27AQN monitor and got it all hooked up as my main gaming monitor. I run a Dell U2412M, a Dell P2715Q, and a Dell S2240M as my chat/internet/movie/whatever displays, so 4 monitors total. The main monitor along with the U2412M and P2715Q run on DisplayPort, the 4th monitor (S2240M) is HDMI
Earlier today I got the new PG27AQN setup on the mounts and get everything fired up, new monitor is great.
But now I cannot get the 4th monitor that is HDMI up to be listed as "active" in Windows. It just refused to show up. I swapped out the S2240M and tried my old monitor as HDMI, same issue. It just will not let me run the 4th monitor and it is driving me bonkers.
I've tried uninstalling the nVidia drivers, I've triple checked that its not doing some weird display setting in windows, I've tried forcing it to extend to it... nothing seems to work. I've googled the shit out of it and can't find a solution.
Windows will just show this:
And not let me extend to the 4th because it won't become active.
Anyone got any idears?
I've already tried the solutions shown here:

I've tried a different HDMI cables as well.
No luck.
