Tried various things to get 10.9.3 beta to boot on my Hack, to no avail. So unfortunately can't test the UP2414Q with it yet. There are a few others with similar problems too, details are in this Netkas thread.

 

@Ricky Romero:

Is there anything particular you had to do to get 10.9.3 beta running with your GTX 760?

 

So far I'm unsuccessful with GTX 770 and 780, I get constant WindowServer crashes instead of the login screen. I didn't have those problems with 10.9.1 or 10.9.2 (though 10.9.2 seems more unstable than 10.9.1 for me).

This is the exact card I'm using on my hack.  I don't have any graphics enablers or hacks needed to make my card work.

 

It's also important to make sure that:

  1. When booting into Windows, the latest drivers for your card will run your 4K display at 60Hz.
  2. Your monitor is set up to receive a DisplayPort 1.2 signal.
  3. You are using a DisplayPort 1.2 cable.  This is the one I use.

I don't know if my motherboard has anything to do with 4K MST output, but it's certainly possible.

 

I tested a Dell UP 2414Q on a late 2012 iMac with GTX 675MX, as well as a late 13" rMBP with Haswell processer graphics, using both 10.9.2 and 10.9.3 beta:

 

Not sure about the 13".  It has Thunderbolt 2 (and therefore DisplayPort 1.2), but I don't know if the Iris graphics will drive 4K at 60Hz. You might want to try it in Windows.

 

Your iMac, though, can't run 4K at 60Hz as it doesn't have TB2.

Thanks for your reply.

 

Enabling MST/DP1.2 is not my problem, but booting 10.9.3 beta on my Hack is.

 

I did already run the display at 60 Hz in full (and HiDPI) resolutions with a 15" rMBP 2013 using 10.9.3 beta, as well as my Hackintosh using Windows 8 (see pic).

A 13" rMBP 2013 I tried couldn't do it however. And yes, the late 2012 iMac (my work machine) can't run it at 60 Hz either, that's the first thing I confirmed.

 

I don't know if my motherboard has anything to do with 4K MST output, but it's certainly possible.

 

Yeah maybe. Out of interest, did you have the NVidia web drivers installed before updating to 10.9.3 beta? What bootloader do you use?

 

I'm pretty much out of ideas. The (clone of the) 10.9.2 install I upgraded to 10.9.3 booted just fine before the update, and I'm writing this from another 10.9.2 install without booting problems.

I can boot 10.9.3 (all the builds including the new beta that just came out) just fine on a hack, but getting retina working at 60hz is a thing. I don't need to replace any files to get the system up, but I can only set 30hz resolutions.

Works fine on my late 2013 MBPR. Would be nice to get this fixed. Using Clover as my bootloader. Graphics card is the GTX 670. 60hz works in Windows just fine.

I did try the NVIDIA web drivers when I was trying to get 60Hz working initially, but I'm 95% sure I wiped all traces of them from my system.

 

I'm using Chameleon v2.2svn r2377 right now.  Maybe you'll find my plist configs useful.

 

One problem I ran into with beta 2 was that my card would only drive my 4K monitor, and not my 27" DVI display.  Gonna test on beta 3 to see if I run into the same problems as you guys.

 

UPDATE: Tried 10.9.3 beta 3 and I'm having no luck getting my second monitor working, though the 4K display is still working fine.  Also tried deleting /Library/Preferences/com.apple.windowserver.plist to no avail.

UPDATE 2: Just tried deleting all the DisplayVendorID entries in /System/Library/Displays/Overrides, also to no avail.  I'm stumped.  Back to 10.9.2 for now.

DVI output over Nvidia cards has been broken since beta 1 for me. Just use both monitors over displayport.

I've just registered to the forum just to contact you-- I am sorry for the PM, I'd have preferred to reply within the thread but the forum for some odd reason, says I "cannot reply to this topic"!

Anyhow, I just want to clarify something. Have you tried running 4k @ 60Hz via Windows on late 2013 13'' rMBP with Iris? Was it successful? If not, do you think this can be possible in the future? (I've read conflicting Intel documents on Iris regarding 4k 60Hz capability, hence I've still got hope)


I did not try any version of Windows on the 13" rMBP (late 2013). It's not my own machine, just a machine at work which I was able to borrow for a couple of minutes for some quick testing, so I will not be able to do any Windows tests.

I don't know if Iris is capable of UHD/4K @60 Hz, but if it is, it probably does need drivers updated for MST support, much like AMD GPUs got in v10.9.2 and NVidia GPUs are about to get in v10.9.3.

Thank you Ricky, I moved your configs in place, set a serial number and will try in a bit (might have to remove P- and C-states too for my board).

Ricky, you're my hero! :D Thank you so much for your help!

With your MacPro6,1 SMBios I got 10.9.3 beta 3 to successfully display the login window! Only on my secondary display though, as the primary Dell UP2414Q was black (I suspect OS X attempted to run it at 30.3 Hz or some other refresh rate that does not work). I logged in and played around a bit. The "Gather Windows" button of the "Displays" preference pane was very helpful for this. ;)

Long story short: 60Hz and HiDPI modes work! That's using a Gigabyte GTX 770 I installed for testing, I'll switch to my usual EVGA GTX 780 soon.

Booting a 10.9.3 beta 2 partition (an upgraded clone of my normal daily-use 10.9.2 partition) worked as well with the MacPro6,1 SMBios. On this partition the NVidia driver is installed, so naturally it complains about not being compatible with 10.9.3 beta and that the OS X default driver is active.

I'm currently using the 2560x1440 HiDPI mode so I can display as much as I can on my previous Samsung 27" display.
 
The only thing that's not quite perfect is that my secondary display (a 24" one with 1920x1200 res) doesn't display anything other than the mouse cursor when I set it to 90° rotation. It works normally at "Standard" rotation, so that's what I'm using for now.

 

Update:

1. to clarify, while I did initially use Ricky's Chameleon config as well, it turned out not to be necessary.

2. Rominator at Netkas suggested that rotated displays might be problematic. Given my secondary display is usually rotated 90° this might well have been a problem for me too.

Oh, nice. I'll give that a go. Silly Apple, caring about the {censored} SMBios lol.

Using the 2013 Mac Pro SMBios fixes it perfectly. 60hz is working now, NVidia GTX 680.

Does anybody know if HDMI 1.4 in 10.9.3 can achieve resolutions greater than 1080p?  Especially interested if it can natively handle 2560x1440 @ 60 hz.  Thanks.

I'm having nothing but problems in the latest seeds.  Beta 7 (13D43) only runs my 2560x1440 display, and when I change the display settings, both displays blank out.  Beta 6 was the opposite: It would only drive the 4K display.

 

Can't win!

Hi,

I've also purchased Dell UP2414Q. I am running the latest 10.9.3 beta using Geforce 770 to drive the screen. I was wondering if anyone was able to get it running at native 2160p at 60Hz. I am only able to select different scaled resolutions (up to 1692p). When i try to change DP mode to 1.2 in OST settings my screen goes blank. I would greatly appreciate any advice.

 

Thanks

Set your SMBios to MacPro6,1 and it should work.

I have tried 10.9.3 (13D43a) on the Dell UP2414Q (DP1.2 enable) and GTX760 and I get a black screen. I also do not get the RefreshRate box, so I cannot change it in case it was on 30.3Hz. Am I doing anything wrong?

 

On 10.9.2 it works great at 30Hz (of course).

 

Cheers!

Exactly the same situation as I currently have.

It might run at 30.3 Hz, so you either need a 2nd display or need to connect remotely to set it to 30.0 Hz. If system preferences won't let you maybe Display Menu will.

 

I replaced my Dell UP2414Q with an ASUS PQ321QE so don't have any personal experience of the Dell with the 3 last betas or so. I had plenty of 30.3 Hz issues with the Dell though…

So have you ever been able to get Dell running using DP 1.2 @ 2160p 60Hz?

Yes, see my earlier post. Beta 4 was worse than 3 for me. Haven't tried since. More details are in my posts at Netkas.
