Ok, so hopefully all the info is here to help explain.
So I built up my desktop (specs below) and got everything working perfectly, with OpenCore 0.6.9, and Big Sur. I was using onboard graphics to drive my 24" Dell 1080p monitor, and that works perfectly at 60hz, no issues. As everything on the machine is working, ethernet, USB, bluetooth, iMessage, the whole lot is fine, I thought I should make it my daily driver, as my 13" 2017 MBP struggles when running anything heavy. So I bought a GT 710 2GB DDR3 GPU from Scan, good price so figured I'd go for it, but struggling to get it to run anything about 30Hz, regardless of the resolution, on my 4K monitor. It's running the 1080p on my secondary Dell monitor at 60Hz fine, but will only do 59Hz if I select low resolution mode in System Preferences and that's grim.
I can post my Config.plist if required, but I've spent the last couple of days Googling, reading forums, checking here, and can't find anything that's helped so far. I added in the "nvda_drv: <31>" to the NVRAM but that didn't do it, and that's also not valid in OpenCore 0.6.9 as I understand. If I check system report, the driver that's loaded is the GeForce 16.0.13 ... no mention of Nvidia web? I've even resorted to trying multiple cables haha.
My question is, do I need to tell my config to ignore the onboard graphics? Or add something different to the boot args? All I did to get the new GPU working is install it and boot up, and it automatically recognised it, but I'm struggling to figure out why it's not allowing 60Hz at 2560x1440 as that's all I want, I don't want to run at 4K.
Specs.
- Intel Core i5 Haswell 3.2GHz Quad Core
- MSI B85M-E45 Motherboard
- 16GB DDR3 RAM
- Zotac NVIDIA GeForce GT 710 2GB DDR3 (Kepler architecture)
- OpenCore 0.6.9
Hopefully that's everything.
