Suddenly it's 1984 - Nvidia 4K 60 Hz support is there, Apple turned it off

Yes I had this problem last night too. I wanted to post it so others can be aware. I reverted and it's back to normal. I hope this doesn't mean nvidia is killing it in the drivers...
 
Try Again?

Hey Guys,

I just tried and was able to enable this.

(tongue twister)

run an nvram -p and make sure both the Nvidia Driver and kext dev mode are in the boot args.

Working spiffy on GTX980 Mac Edition EFI card.

Yeah I had these boot args too and it didn't work.
boot-args kext-dev-mode=1 nvda_drv=1

Once I revered to the previous driver version and rebooted, it just worked again.
 
Hmm, I only tested on Mac Edition GTX980 card with Asus PQ321Q, which uses MST mode for 60Hz. Definitely still worked.

Are you guys all SST?
 
I am using the asus PQ321q in MST mode with a GTX 980 and it didn't work for me. Maybe it's an efi thing?
 
@MacVidCards : hi and thanx for your work.

Context :
I have a Mac Pro 5,1 (mid-2010) with Yosemite 10.10.1.
I installed a PC version ASUS Nvidia GeForce GTX 980 4GB in my Mac Pro and connected it with DisplayPort to a 4K monitor Dell UltraSharp UP3214Q (DisplayPort 1.2 activated).
Of course, I installed before the last CUDA Driver (6.5.33) et the Nvidia Web Driver (343.02.01f01, not yet compatible wit 10.10.2 beta).

Results :
Mac Pro 5,1 (mid-2010) + Yosemite 10.10.1 + GTX 980 (PC version) + Dell UltraSharp UP3214Q
>>> 4K@30Hz is ok, but 4K@60Hz impossible.

Mac Pro 5,1 (mid-2010) + BootCamp Windows 8.1 64bits + GTX 980 (PC version)
>>> 4K@60Hz works perfectly !

Mac Pro 5,1 (mid-2010) + Yosemite 10.10.1 + Radeon HD5870 Mac + Dell UltraSharp UP3214Q
>>> no display at all !


My questions :
1) I know GTX 680 is already natively supported by Apple Yosemite. Will this graphic card GTX 680 support the 4K@60Hz on my Mac Pro 5,1 ?
2) GTX 980 is not yet supported by Apple in Yosemite. Do you think it will be ?
3) In the meanwhile, will your GTX 980 MacVidCard version support 4K@60Hz on my Mac Pro, or do I have to wait for Apple to "authorize" 4K@60Hz ?

... waiting for my ATI R9 280X for the same tests, noticing that card is natively supported by Apple Yosemite 10.10.
Thanx !

Just so I understand correctly, if I have a flashed 5,1 Mac Pro with a 980 GTX and I connect a UP3214Q , it will not allow 4k@60Hz? This monitor is on Apple's 4k compatibility list and it says they support 4k@60Hz as long as you enable MST.
 
@MacVidCards : I read this interesting thread but didn't try the mod. I'm afraid it's too complicated for me.
And, meanwhile Apple officially support GTX 980 in Yosemite, I prefer having a graphic card fully already supported, like the ATI R9 280X or the NVIDIA GeForce GTX 680.

@Zorn : YES, except maybe, if you apply the kext modifications described by MacVidCards (not tested by me).

At the moment, Apple maintain 2 limitations :

- OS X Yosemite does not natively support recent graphic cards like GTX 980
>>>>> the trick : install Nvidia Web driver but you have no boot screen, +other compatibility problems...

- OS X Yosemite software limits 4K@30Hz on "old" Mac Pro, except Mac Pro late 2013 where it is 4K@60Hz only on some compatible monitors (http://support.apple.com/kb/HT6008)
>>>>> Apple will surely offer 4K@60Hz as soon as they will sell 4K or 5K monitors, to prevent people to buy Dell, Samsung, Sharp...

Has anyone tried this under 10.10.2?

I am cloning my disk and will update today and see if the hack still works in 10.10.2, and see if the newer nvidia drivers still break the 4k @60hz kext hack.
 
The 10.10.2 update broke 4k60hz support hack on my mac pro 2010 (asus PQ321Q) and I could not replace the nvidia 343.02.02f01 driver with the previous one (343.01.02f03)

"Mac OS X version 10.10.2 (14C109) is not supported with this package. Please see NVIDIA’s website for further driver information"

I will have to revert to the 10.10.1 cloned partition.

Why couldn't apple allow us to use 4k60z on a mac pro 2010 ?

Cause Apple is a piece of ****.

Somehow the update on the clone drive also set a flag to install the update on my main drive and hosed my system. I tried to get the 980 working with the MST 4k hack on 10.10.2, and after frustrating hours of failure, I gave up. Apple Wins.

I am retiring my asus 4k and moving back to my HP 30", it's just too much of a hassle and I don't want to be stuck to 10.10.1 and those specific drivers.

It's too bad there isn't a comparable 16:9 31.5" SST 4k to my taste. I am gonna try to sell the asus 4k monitor.

One other thing to note is the performance of the UI was struggling and laggy for me on 4k. I had a chance to try out the new mac pro with dual D500 and it worked way better, it was a smoother experience.
 
Working but not working.

I just applied the "fix" to 10.10.2 with Web Drivers.

Screen looks great at 4K 60Hz. Problem is same as I saw in 10.10.1, the right half of my Asus PQ321 is perfect at 60-Hz. On GTX980 Mac Edition.

Left half looks great but mouse cursor doesn't show on that side.
 
I was able to get the hacked extension working once in 10.10.2 and latest display driver, but I noticed the same thing that the mouse was messed up and would keep disappearing on all sides and then, the video never worked again.

It was at that point I gave up.
 
I got an email from someone claiming it was still working just fine.

I discovered a 1.10 firmware for my Asus so installed that but still have difficulty getting to desktop and when I do I still have cursor only visible on right side of screen.
 
You think this is a 980 issue, display driver issue, or apple system issue? I might try my GTX 680 EFI as a last ditch effort to keep the 4k monitor. I would be downgrading my video card, but at least keep the monitor.

I don't know. I imagine that Nvidia is like us in that they are overwhelmed by the variety of different 4K displays and how many of them seem to act differently despite in theory adhering to same standards.

I have heard from someone with a Dell UP2414Q who says that the 4K fix still works on that. It is possible that Nvidia has only tested on that and those of us with other displays are just out of luck, at least for 10.10.2

I am going to also try with a 680 EFI card and will update this post with news.
