Yosemite 10.10.1 + GTX970 Nvidia Driver Experience

4K HDMI 2.0 Yosemite 10.10.1 + GTX970 Nvidia Driver Experience

I received a LG 49UB8500 4K TV/Monitor for Christmas and purchased a Gigabyte GTX970 card to drive it. I successfully set everything up with Windows 8.1 and am able to drive the display via the HDMI2.0 port at 3840x2160p60 with full 4:4:4, which is critical as a computer monitor.

I was just about to blow away my 3 year old Lion drive and abandon Hackintoshing, when I received a notification from apple to upgrade to Yosemite for free. I spent the day yesterday, thanks to tonymacx86 and MacMan, creating a new Yosemite 10.10.1 drive. I had a few issues that reading through the Forum helped me resolve and then I was up and running with the HD3000 graphics in my 2600K via both HDMI and DVI.

I then installed the Nvidia Web Driver 343.01.02.01f01, modified the boot flag per the guide and restarted. I only had the HDMI cable plugged in. I got the Bios display and the OS X start screen and then it went black. After wasting some time, I figured out that the card was outputting to the DVI ports, but not HDMI. With a monitor connected to DVI, I could adjust the video settings. After another reboot, both the DVI and HDMI, with controls for Monitor Mirroring became active. With Mirroring activated, the driver presented lots of common resolutions for the LGTV including 3840x2160p30 in full 4:4:4 color mode. This looked amazing! Just like my Windows 8.1. Unfortunately, 3840x2160p60 was not an option. I tried SwitchResX and another utility to try to force the 3840x2160p60, but was unsuccessful. With Mirroring not activated, when the HDMI was active, which seemed like about every other reboot, the driver presented lots of very unusual resolutions, most at 24Hz.

One question I have, I am currently using MacPro3,1. Does anybody know if the video scaling options change with MacPro4,1 or MacPro5,1 or if there are other settings worth attempting? Also what are the tradeoffs?

I then installed the latest Nvidia Web Driver 343.02.01.01f01 and restarted. When booting initially, the OS X driver was active still and I needed to reinstall and make sure the Nvidia Web Driver was selected as the default. Then when rebooting again, both the HDMI and DVI ports where active, whether in mirroring mode or not. Awesome I thought. But then realized that the Driver limited my output to 1920x1080p60 4:4:4 max. I again tried the SwitchResX, etc. with no success pushing to higher resolutions on the LG display. This is at least a useable solution, but doesn't let me take full advantage of my 4K display.

Thanks!

Hey,

I've just completed a build using the MSI GeForce GTX 970 on 10.10.1 and using the Samsung U28D590 (4K).

From what I've read on these forums, the Webdrivers from Nvidia will only work on Mac Pro 3,1 (no idea why).

The only difference I can see on what I'm using is that I'm using the GPU's Display Port to connect to my monitor. Are you able to try this?

Otherwise, I found these instructions from Flo655 really useful:

Clean install of Yosemite with Clover, without the video card.
Add nv_disable=1 in boot args
Connect the card
Reboot
Install the latest NVIDIA Web Drivers
Remove nv_disable=1, add nvda_drv=1
Reboot, but don't connect your screen to the video card yet.
Go into the bios and disable IGFX, select PCIe 1st slot as the first selection. This will enable the bios to be displayed on your main screen connected to the video card. Now you can connect your screen to the video card.
Boot into OSX, this will now be even faster than before

Hope that helps - let me know if it does!

i am using LG 42UB8200 with asus GTX 970 on my hackintosh
i need to use DVI to HDMI adaptor to output normally, no luck when i directly plug in to 970 hdmi port.

but all i got is 3840*2160/30Hz max..
i guess it is because there is no any MAC using hdmi 2.0,
from apple support pages state that currently MAC with HDMI 1.4 can only output 4k@30hz.

and everything fine when i using 343.01.02f01 nvidia web drivers
after update to 343.02.01f01 (the latest one), it can output 4k/30hz, but the image look blurry.
after roll back to 343.01.02f01, it back to normal

Yes, the latest Nvidia Web Driver - 343.02.01f01 - enabled HDMI but limited to 1080P. DVI - HDMI works but limited to 4k 30hz.
The previous Nvidia Web Driver - 343.01.02f03 - HDMI port did not work. DVI - HDMI had 4k60Hz.
Tested that in 10.10.1 with GTX 980 in LG 49UB8500.

how DVI-HDMI work with you via GTX 980 in 4k@60hz !!!

the DVI limited to 33hz not over to 60Hz

Digital[edit]
Minimum clock frequency: 25.175 MHz
Single link maximum data rate including 8b/10b overhead is 4.95 Gbit/s @ 165 MHz. With the 8b/10b overhead subtracted, the maximum data rate is 3.96 Gbit/s.
Dual link maximum data rate is twice that of single link. Including 8b/10b overhead, the maximum data rate is 9.90 Gbit/s @ 165 MHz. With the 8b/10b overhead subtracted, the maximum data rate is 7.92 Gbit/s.
Pixels per clock cycle:
1 (single link at 24 bits or less per pixel, and dual link at between 25 and 48 bits inclusively per pixel) or
2 (dual link at 24 bits or less per pixel)
Bits per pixel:
24 bits per pixel support is mandatory in all resolutions supported.
Less than 24 bits per pixel is optional.
Up to 48 bits per pixel are supported in dual link DVI, and is optional. If a mode greater than 24 bits per pixel is desired, the least significant bits are sent on the second link.
Example display modes (single link):
HDTV (1,920 × 1,080) @ 60 Hz with CVT-RB blanking (139 MHz)
UXGA (1,600 × 1,200) @ 60 Hz with GTF blanking (161 MHz)
WUXGA (1,920 × 1,200) @ 60 Hz with CVT-RB blanking (154 MHz)
