60Hz 4K on Mavericks with GTX 760? [UPDATE: 10.9.3 works [UPDATED UPDATE: maybe]]

[maleorderbride]

I've just connected a new NEC EA244uhd to my hackintosh system with GTX 760 video card. Three OS X versions were tested - 10.9.4 (web driver), 10.9.5 (native and web driver) and 10.10PB2 (web driver). In all cases HiDPI mode @ 60Hz worked perfectly with no additional patches/hacks. 

 

The key to these problems are the actual monitors chosen. 

 

MST is not working under OS X in 10.9.X or 10.10 so far with stock or web drivers. Until Nvidia drivers enable MST you will not be able to get 60Hz @ 4K with an MST only monitor.

 

The sidestep is to make sure that you purchase a display that supports SST instead. The Samsung U28D590 is one such display, as is (apparently) the NEC EA244UHD.

 

As far as IPS-level displays, there are these two that *appear* to be SST, but the lack of widely available North American releases make it difficult to confirm:

Good to know, thanks for the report. Did you use the MacPro6,1 SMBios?

No. I'm using iMac late 2013 (with Clover).

MST is not working under OS X in 10.9.X or 10.10 so far with stock or web drivers. Until Nvidia drivers enable MST you will not be able to get 60Hz @ 4K with an MST only monitor.

As far as I know, EA244uhd is a typical MST display. I wasn't sure if what my monitors shows in the menu (3840 x 2160 @ 60Hz) is really true. But interface operations, mouse cursor movement are absolutely smooth. Ocean Wave benchmark shows something like ~59... fps (almost 60).

 

It means one of these two options:

1) depending on MST implementation, MST may or may not work with NVidia or stock drivers;

2) EA244uhd uses SST.

 

By the way, Anand says that EA244uhd uses MST:

"One difference with the NEC EA244UHD compared to other UHD monitors so far is that it defaults to MST being enabled for DisplayPort 1.2"

I have posted how to enable MST mode at MR.

 

Requires Yosemite and an MST display.

Read just below that--it uses SST whenever it detects a problem with MST. You do not have working MST in 10.9.5.

 

Great to hear Rominator!

Mind posting a link?

Mind posting a link?

It's on the previous page.

 

With regard to that MST solution... it works, but I lose the ability to run multiple displays. If I put 2 or more GPUS in the machine and hook displays up to them it's random which one actually works when I get to the log in prompt. The GPUs show up in system profiler but only one of them will indicate a connected display.

It looks like I will be selling this Dell display. I have found the perfect display for a really good price.

It will not be over 800€ which is really great considering it's VA panel and maybe it will run over SST too.

It will be released in December, I already ordered one.

Yes, NEC may use SST. But I haven't seen any evidence that 4k @ 60Hz is supported by ea244uhd in SST mode.

[Redtigerxx]

So I got my UP3214Q to work at 4K and 60HZ via the post on Macrumors with the MSI GTX 760 2GB. The only problem is now that the video card runs the fans at 100% all the time. Any ideas how to fix that? iStats does show the temp of the GPU, but doesn't give the correct RPM for the fans.

I upgraded my Hackintosh to Yosemite as well, and changed from Chameleon to Clover boot loader at the same time (took me a while to figure out that my mainboard won't boot Clover in UEFI mode).

 

As I didn't want to mess with kexts I just switched to the Mac Mini SMBios as mentioned on the previous page.

 

I still don't get a signal on my ASUS PQ321Q after booting, the login screen is on my secondary 1200x1920 display instead. As with Mavericks I turn the ASUS PQ321Q off and the on again, so the login screen will move over to it, and all is fine. 60 Hz and everything.

[Backslash]

I joined the Hackintosh community and installed OS X Mavericks on my PC because I assumed it would handle 4K monitors better than Windows, because of the Retina display support on the MacBook Pro. 

I did a short Google scan and found out Mavericks 1.9.3 supports 4K out of the box... So I installed Mavericks, got it up and running and ordered my 4K monitor. I choose the Dell UP2414Q because of the high PPI and accurate color display, to bring 'Retina' to the Desktop PC

 

This week it arrived. Everything looked stunning, except I found my mouse cursor laggy... I stumbled into the 30 Hz limitation... I was getting desperate and almost gave up the Hackintosh project. In my search for a solution I came across to this topic.

 

Luckily I found a way to run on 60 Hz! Proof:

 

What I did was basically followed this post from  =)(= in this topic as a starting point, but I have a different setup.

I run Mavericks 10.9.5, Nvidia Web Driver on a GTX 760. I have the Chimera boot loader.

SMBIOS of iMac 12,2. 

I run a dual monitor setup. I found out by accident how to get the UP2414Q running in 60 Hz.

​I boot with the secondary monitor on, UP2414Q off. After Mavericks is completely booted, I turn on the UP2414Q, and voila, it was running in 60 Hz  

I notice no mouse or animation lags, so I am certain it is 60 Hz.
 

[=)(=]

I can confirm that Philips BDM4065UC is SST.

 

 

I booted Yosemite with stock AppleGraphicsDevicePolicy.kext and latest Nvidia Web Driver.

[boli]

Just a heads up:

After installing the newest NVidia v343.02 driver my PQ321 no longer worked with MST in 60 Hz. I reverted to v343.01 and it works again.

[boli]

Another heads up:

I switched back to the Dell UP3214Q instead of the Asus PQ321 again. You might remember that (unlike the Asus) the Dell didn't work for me at 60 Hz back in Mavericks. I haven't tried in Yosemite until today and I'm happy to report that the Dell now works in 60 Hz.

 

I still need to have it powered down on boot, while a second (non-UHD) display is attached and gets the login screen, then I can turn on the main display and the login screen will jump over to it.

Did you try hdpi settings in yosemite? Can you please, post some screenshots?

I found a few people complaining about the philips VA panel: the color shift (top2bottom), vertical banding, also pixels are not square, yet these are a few people who bought it, overall it seems to be a very nice monitor.

I have a 27 2560X1440 display(evga 750 ti dp 1.2) and that Philips seems like a good monitor, its the same PPI at native res 110 but I would like to hear from your experience with hdpi under yosemite. 

Thank you.

Anyone have any luck getting 4K at 60 Hz with OS X 10.10.2? I had it working using this:

 

- Dell UP2414Q

- Macmini6,2
- Mac OS X 10.10.1
- NVIDIA Web Driver 343.01.02f01

- MSI GTX 760 2 GB
- Clover r3113

- FakeSMC 6.11.1318

 

I upgraded to OS X 10.10.2 (using combo updater) and NVIDIA Web Driver 343.02.02f01 (since the old driver version will not load under OS X 10.10.2), but basically I had no success.

A lot of people are struggling with 4K and 10.10.2. My friend spent hours trying to get his 970 to work with no success.

 

Perhaps revert back to 10.10.1 (if you cloned it, that is!), and wait for newer drivers.

[mgldan]

Yeah, I used SuperDuper to go back to 10.10.1 and 343.01.02f01. I tried a couple things to get 343.01.02f01 to load under OS X 10.10.2--plist editing and using Pacifist to install mixtures of the old and new web drivers--but I was also unsuccessful.

[soulz]

scary... keep us posted

[Amethyst]

Do you guys think the next kext version can repair our 4K 60Hz?

[Rampage Dev]

Have you tried the old patch for adding Support?

[Amethyst]

Yes i have patch apcp.kext to enable 4k 60hz on my real mac pro but nothing works.

[boli]

Just tested: a Dell P2715Q does not offer its native Ultra HD resolution on a 27" iMac14,2 (fall 2013, GeForce GTX 775M) running OS X 10.10.2, but only 2560x1440. I know this iMac can run other Ultra HD displays at 30 Hz, but for now, not even this works.

 

Updates:

• The newest NVidia web drivers did not help.
• The display did run at full resolution and 60 Hz on a 5K iMac15,1 (fall 2014, AMD Radeon R9 M290X) running OS X 10.10.1!

[mgldan]

Yeah, this is basically the most frustrating thing ever. For me, only a handful of definitions even result in a signal on the UP2424Q: Macmini6,2; iMac14,1; and iMac14,2. Macmini6,2 is the only one that gives 60 Hz, and the other two give 30 Hz. What's even worse is that the newer definitions, Macmini7,1 and iMac15,1, don't even turn the monitor on. There's no signal at all. I don't get why that is, since real Macs with those definitions do support 4K at 60 Hz on this monitor, at least according to Apple. And of course I still can't upgrade to OS X 10.10.2 without losing the 60 Hz.

 

I wouldn't mind using Macmini6,2, but sometimes when I start to watch a Flash or QuickTime video, it forces the Safari tab to reload. You can just restart the video and it will play the second (or third) time, but it is super annoying.

 

I wish there were a way to figure out what about Macmini6,2 enables the 4K @ 60 Hz in the first place, so that maybe a separate kext or something could be written. But it's just beyond my expertise.

 

I guess all I can do is wait until OS X 10.10.3.

[mgldan]

Actually, I spoke too soon--MacBookPro11,2 (but not 11,1) will also give 4K at 60 Hz, with everything else the same as in post #141. Same issues with graphics crashes as in my last post though.
