nvidia surround

I have a gtx1070 which has a max resolution of 7680X4320@60Hz. I have an Oculus Rift I run steam virtual desktop on. I currently have a 1920X1080 monitor and a Fit 4K headless display emulator. In virtual desktop I can see the emulator as a 4K monitor 4096X2160. Works great great money saver but...
