Hi Insanely tech gurus,

 

I've managed to get my studio machine up and running after a few weeks of fighting with it. Big Sur on a MSI MAG Z490 Tomahawk, 10th gen i5 10400F (no iGPU).

 

My ASUS GTX670 runs fine OOB on 3 screens, but in order not to get a blank screen at boot, I have to unplug top DVI and display port. Bottom DVI is fine on it's own. I can re-plug when i get to the open core loader screen.

I'm presuming, just like USB mapping, which is also on my list of post to do; do I need to map GPU ports? and if so, how do I go about that please? I am more or less a complete noob at this having built my last hack 9 years ago.

 

Thanks for reading.
