Default Since change to NVIDIA GPU no video

Hello,

Because I'm working on some graphical stuff I changed my GPU from a Sapphire Pulse Radeon RX 550 4G GDDR5 (AMD) to a Gigabyte Geforce GTX 1050 Ti (NVIDIA, I need the CUDA). Since than my videoscreen stays black.

Anybody an idea?

I'm working with Reaper v6.20 on a Windows 10 Pro (19042) desktop with AMD Rhyzen 7 1700x Eight-Core, 16 Logical Processor(S) and 32GB Ram

uninstall all the GFX card software, re-download it but this time only install the drivers, not all the bells & whistles offered with NVidia drivers. Many of us on here have had the same issue.

No problem! Glad it was an easy fix.

I was just wrestling with a Nvidia video card.

Their drivers (if and when you can find them for your OS version) need to be used.

They store the flag for loading their own driver in NVRAM by default. If your logic board doesn't support that, there's a workaround to use the EFI partition of your system drive to store that flag.

The NVRAM variable must be expected to be at a particular memory address or something... Clear your NVRAM before starting to install and avoid that wild goose chase.

If your OS has a system integrity protection feature to prevent all non native kexts to run, this will need to be disabled. (eg. SIP on Macs).

Now all the badmouthing Nvidia is getting is starting to make more sense!
