Solved! connect three monitors with surround and have one extra monitor

[Fly!]

Hello everyone
Here is a problem I cannot solve. I have four monitors connected to my computer. I'd like to connect three monitors into one and have the fourth monitor as a support monitor. Nvidia only allows three or four monitors to be connected in surround, If I try three monitors the fourth will simply be switched off. Does anyone have a solution?

Install another video card, if you are just going to be using it as a simple 1080 output screen can use a USB 3 external card.
