Need help getting my GTX1050 to work

I just got a GTX1050 to try and get my old Hackintosh (10.11.4) working with 4K.

After installing, it shows up as an "Unknown" card.

I followed the instructions at https://www.tonymacx86.com/threads/nvidia-releases-alternate-graphics-drivers-for-os-x-10-11-4-346-03-06.188837/ including ticking "nvda_drv" in Clover Config, and enabling the Nvidia driver from the Nvidia Driver Manger System Preference panel.

I have the latest Nvidia web driver installed.

But it still won't recognize the card or go above 1024x768.

My config.plist is probably a big mess (the result of years of on and off tinkering) -- I posted it here: https://pastebin.com/v0HYBwB7

My mobo is a rather old Gigabyte ga-x58a-ud3r.

Can someone help me out?

Should I manually add nvda_drv=1 to config.plist? Where would I do that? (Ticking that box in Clover Configurator did not add that actual text. And it was magically disabled after reboot.)

Actually I just realized that if I tick nvda_drv in CC, then save, then re-open config.plist, it is unticked. Confused.

Please help! Thanks!
