The graphics are running very glitchy. (Possibly related issue, the Wifi seems to be connected but no applications will connect, especially the App Store and Safari.)

I am a first time builder. I recently installed the Sierra OS 10.12.6. I have recently solved another issue where I was not able to boot from my Sierra native SSD. A forum discuss an issue with iTunes and needing to have a dedicated graphics card. So I changed the display in my BIOS setting to use the GPU and disabled the integrated graphics. I was then able to get boot, login and get to the desktop.

However, I have two new problems. The one I am hoping to solve on this thread is that the graphics are running very glitchy. I have not been able to upload any drivers since there is no internet. It's possibly due to the HDMI 2.0b from the graphics card going into a HDMI 1.3 display, but that does not feel like the problem. Steps taken:

-I have installed the Nvidia Web Driver.
-The NVidiaWeb box is checked in the config.plist.
-Argument "nvda_drv=1" is NOT checked
-Have NOT TRIED installing the Lilu.kext and NvidiaGraphicsFixup.kext to /Library/Extensions as the issue seemed unrelated (Could be wrong)

The other issue is that the applications are not connecting to the Wifi, though the computer seems to be connected to WiFi.

What can I do to make the graphics run smoothly?

The problem is most likely the lack of native NVRAM support.

BIOS - Disable Integrated graphics - Set PEG as Primary
Use a digital connection - DVI or HDMI - VGA is not supported.
Boot with nv_disable=1
May need to update Clover
Install web drivers
Config.plist - Do not inject Intel or Nvidia graphics and no ig-platform-id
Config.plist - Disable SIP fully - CsrActiveConfig 0x67
Edit config.plist - NvidiaWeb = true as per Link
May need to emulate native NVRAM - Problem 6
Remove nv_disable=1 from config.plist
May need to install Lilu.kext and NvidiaGraphicsFixup.kext to /Library/Extensions

Potential Problems :
HDMI 2.0 is not supported - Use HDMI 1.4
If your graphics card has more than one output of the type that you are using then try another one.
