Quadro M6000 with Centos 7 not allowing GUI with proprietary drivers

I am taking output through HDMI port of M6000 card. But somehow the configuration is not able to detect the monitor and displaying everything in text. I tried tweaking the xorg.conf to the PIC BusID of monitor yet no success.
Can anyone please help me get a patch or correct configuration for setting the nvidia with proprietary driver on Centos7 to give output through HDMI.

Nouveau divers were working perfectly, but I can’t use CUDA without proprietary drivers. So, I want to install proprietary drivers and use CUDA.

Please help me
