Can't get full resolution in Nvidia Surround mode

Hello, I think it might be better to start a topic for this, doesn't quite fit in the PC build topic.

Some time ago I've tested triple wide Nvidia Surround on the following setup and it worked like a charm:
GTX 780
One Dell 2209wa 1680x1050 (native) connected by DVI->DVI
Another Dell 2209wa 1680x1050 (native) connected by DVI->DVI
One cheap Asus monitor (I think it was a VS228DE native 1920x1080) running 1680x1050 connected by HDMI->DVI cable
Sadly I don't remember the drivers I was using then.

I was able to run the desired 5040x1050 @60Hz without a problem.

My new setup isn't working correctly.
GTX 1070
One Dell 2209wa 1680x1050 (native) connected by DVI->DVI
Another Dell 2209wa 1680x1050 (native) connected by HDMI->DVI
One Dell p2212H native 1920x1080 running 1680x1050 connected using a DP->DVI passive adapter and DVI->DVI cable
Using the latest drivers

The monitors work fine until I enable surround. When that happens, I can only choose a maximum resolution of 3840x1024. For some reason it's defaulting to 75Hz but I CAN choose 60Hz.

What am I doing wrong? Is it because of the passive adapter? Does it HAVE to be active, even in a new card like this? Would a DP->DVI cable work instead? Am I shit out of luck until I get a monitor with DP input?

Mayday on

    In case anyone ever has the same problem - all monitors need to have the same sync polarity. P2212H had a different one than the 2209wa which was causing the problem.
