So let me preface this by saying that I believed I was having the same black screen boot problems others have been, and have just been incredibly unlucky in finding a solution. That may still be the case, but I've been troubleshooting and I think I might have a different problem that just seems like it's the prior.
Like many others with the Nvidia drivers, my boot sequence gets about half way, then the screen goes black, followed by "no input". Currently, I'm using a P7H55-m pro mobo, EVGA GTX 970, and an i5 Lynnfield CPU. Unlike most others have reported, this problem didn't start after I installed the drivers. I actually booted up and used my Mac perfectly fine for hours, watched some netflix, then suddenly the screen went black, and I've had these boot problems ever since. I saw many were having this problem, so I tried all the solutions I could find. I swapped sysdefs to multiple different ones: mac pro 3.1, 6.1 with the patch, iMac 14.2 and everything in between, but still have had no luck. I tried changing my system to read my GPU as GFX1 instead of 0, no success there either. I've tried uninstalling and resintalling, checking to see if I had Inject Nvidia on somewhere, and everything in between, still no luck. Of course, I can boot no problem with nv_disable=1.
However, today, I tried screen sharing from my other install after the screen goes to "No Input" and was able to access it. Looking under about this mac, I saw it was reading my card "GTX 970 4096mb" but my display was reading as "Built In Display". I tried rebooting with nv_disable=1 and saw that when I boot this way, it reads my TV as the display instead, which got me thinking. Is there something wrong with my HDMI port when using the Nvidia drivers? I only have a small SSDT using one of toleda's patches for HDMI audio from before, and no DSDT. Is there something I can do to regain this HDMI function if I'm correct? Thanks for any insight.
