Mac Pro Late 2013 and Samsung 4k monitor problem

The monitor was sent in for repair and they say the replaced the whole main board. Samsung admits that there is a compatibility problem with Macs, but I don't know if they mean the tearing or perhaps various issues.

Okay so I never had to locate this thread with my first 2013 Mac Pro because it had two D300s and I was using my Phillips 4k monitor at 4k 60hz with zero tearing or need for any adjustment. I can confirm perfect use with the same DP 1.2 cable and monitor using my 2014 15" MacBook Pro with a GTX 750 card. However, today I received my newer 2013 Mac Pro with two D500 video cards installed and whamo, lots of problems. Very difficult for the Mac Pro to even boot off the 4k monitor and the tearing on the right side is there at every single resolution from 1920x1080 all the way to 3840x2160. I have always had my Phillips monitor set to DP 1.2 and can confirm that the D300s worked perfectly at 4k 60hz. So this is DEFINITELY an Apple/AMD video card problem. Dunno if it's a driver fail or the chipset or firmware on the video cards, but it would appear that Mac Pro owners who splurged for the higher end video cards may have a good potential class action case vs. Apple, as from this thread it's obvious Apple has known about it for months and tried to blame other manufacturers and offered other lame excuses while ignoring its customers. Personally I won't waste another moment hacking their display driver to try and get 50hz out of these insanely expensive video cards when at this price they should be giving 120hz. After years of avoiding it, I think it's finally time to build a hackintosh -- if I'm going to have to hack OS X to make it work with Apple's hardware, I might as well build a faster, cheaper & easier to upgrade box which doesn't have me hanging as Apple takes their sweet time to fix (or not) a basic video driver issue on a $4k computer which brags in the sales literate that it can run 3 separate 4k displays at 4k 60hz resolution. Maybe it's the post-Jobs curse, but quality and customer service at Apple has become a real issue.

I'm frustrated with these issue. I have a Samsung U28D590D and a Mac Book Pro 2013 with Retina display 13inch. I did everything people on this discussion suggested and I could get 49.8Hz but not 60Hz. and I realized I can't go beyond 440 pixel clock and as a result, I can't go beyond 50 Hz and I'm just wondering if it's a driver issue or a hardware incompatibility. Does my Intel Iris Graphics support 4k up to 60Hz? that's what it says on the website but I still can't get it to work with 60Hz and it's a pain to watch movies with the current refresh rate. Any ideas?

Wauw - not impressed! I just updated to 10.9.5 - and the tearing is still there on my Philips 288P (288P6LJEB)

I really expected this to be solved sooner than later (later being Yosemite).

Any other 10.9.5 results?

Not sure what is funnier, that I couldn't reply to Apple threads today (including this one) via the newly installed iOS 8 version of Safari on my iPhone 5, or that I was able to solve this Mac Pro 4k tearing problem by: wait for it.... RETURNING THE MAC PRO TO THE APPLE STORE. 😁😁😁

Hey there, somewhere in the thread you will find that the 13" MBP will not support 4K 60 Hz, unfortunately,

Hello,

I am writing in order to maybe get some answers to a problem I have …

I am trying to get my mouse to work properly in this scenario :

I have a Mac Pro late 2013 - 6 Core with 2 x AMD FirePro D300 cards.

said to support :

“up to three 4K displays (3840x2160)

-- two using Thunderbolt 2 ports and one using the HDMI port

-- or as many as six displays up to 2560x1600 using Thunderbolt 2 ports “.

I want to connect my Mac to my 2014 Samsung UHD 4K TV UE48HU7505, for music production.

The Samsung got HDMI 2.0 ports. I am using the dedicated ‘PC’ port.

I am using a 4K compatible HDMI - Mini DisplayPort adapter along with a 4K Supra HDMI cable

to connect into one of the Thunderbolt ports on the Mac.

When connected, I get a nice Mac desktop on the TV, and I can chose different resolutions.

For now, 3840 x 2160 in 30Hz is the best I can achieve, both workspace and mouse movement.

But naturally in 30 Hz, the mouse is not very good.

It is laggy and far from precise.

Now, I have followed this thread, and read most of it,

and I’ve learned that people have been able to run in 3840 x 2160 with 60Hz.

So will I be able to do the same with my setup ?

A a starter I guess I will need the DisplayProductID document for the 4c2D folder.

Any one able to help me out here ?

I honestly have no clue how to make such a document …

Any help highly appreciated !

Cheers,

Geir

Using 4K displays and Ultra HD TVs with Mac computers

says

You can use 4K displays and Ultra HD TVs with your MacBook Pro (Retina, Late 2013 and later), Mac Pro (Late 2013), and iMac (27-inch, Late 2013) computer. You can use these displays at the following resolutions and refresh rates with the built-in HDMI port.

• 3840 x 2160 at 30 Hz refresh rate
• 4096 x 2160 at 24 Hz refresh rate (mirroring is not supported at this resolution)

With OS X Mavericks v10.9.3 or later, the following DisplayPort displays are supported at their default usingsingle-stream transport (SST) at 30Hz.

• Sharp PN-K321
• ASUS PQ321Q
• Dell UP2414Q
• Dell UP3214Q
• Panasonic TC-L65WT600

MacBook Pro (Retina, 15-inch, Late 2013) or Mac Pro (Late 2013) also support multi-stream transport (MST) displays at 60 Hz . These displays need to be manually configured to use MST. Follow the steps below to use the display's built-in controls to enable this feature.

• Sharp PN-K321: Choose Menu > Setup > DisplayPort STREAM > MST > SET
• ASUS PQ321Q: Choose OSD menu > Setup > DisplayPort Stream
• Dell UP2414Q and UP3214Q: Choose Menu > Display Setting > DisplayPort 1.2 > Enable
• Panasonic TC-L65WT600: Choose Menu > Display Port Settings > Stream Setting > Auto

Your Mac will automatically detect an MST-enabled display. However, your display may require a firmware update to support 60Hz operation. Please contact your display vendor for details. If your specific DisplayPort display is not listed above, check with the display’s manufacturer for compatibility information.

Hi,

Yes, I've already read that 🙂. but i was looking for a way to override those 'limitations'.

This thread adresses a few options for other Samsung Displays, but I was looking for a working solution for the UE48HU7505.

I believe it should be possible to 'fool' the driver likewise described earlier in here ...

G

I can't find the detailed specs for ou TV. What dies it say? Irt may only support Single Stream Transport (SST) and thus on 30 Hz. Yo need Multi Stream Transport (MST) for 60 Hz

I'm not sure. I have to look in the manual, but I am starting to feel anxious about this now.

If you're right, I'm down ...

BTW ... When we're talking 30 or 60 Hz, are we talking fps or Mbps ?

Thanks for your time 🙂

Unless your 4K TV has a displayport 1.2 connection (I don't know of any TVs that do), there is no way to drive it at 60Hz from a Mac Pro or MacBook Pro. The Apple HDMI connection won't support it, and neither will a minidisplayport to HDMI converter. Word is that the newest standard of HDMI may well be able to support the required bandwidth, but as of now Apple doesn't offer 4k via a thunderbolt(minidisplayport) to HDMI adapter. To drive a 4k monitor at 60hz from your Mac, you must have a Thunderbolt (minidisplayport) to display port 1.2 adapter (like this one from Amazon http://www.amazon.com/Accell-B143B-007J-UltraAV-DisplayPort-6-6-Feet/dp/B00A7R9I 22) -- which requires your 4k monitor (or 4k TV) to have a displaport 1.2 connection.

No, my TV don't have a diplayport.

So this actually comes down to Apple and their support ?

The TV supports HDMI 2, and as you also mention, this should be good enough for required bandwidth.

And Thunderbolt, does it not support the 60Hz rate ?

I am using this adapter from HDMI to minidisplayport.

I honestly thought it could do the job ...

Kind of weird if you ask me.

Thanks,

I do not understand this statement "And Thunderbolt, does it not support the 60Hz rate ?".

I am using a mini displayport to displayport cable (version 1.2) on my 4G Dell monitor. That monitor is discussed in

http://support.apple.com/kb/HT5918

It plugs into a Thunderbolt port of the nMP and I get 4K and 60 Hz when I set the monitor for displayport 1.2 as the article says

So I would imagine that if Apple ever supports 60hz over HDMI 2, my guess is that'll require a new Thunderbolt to HDMI 2 converter cable. But for apple to support HDMI 2 over thunderbolt (or via a future Mac with an HDMI 2 port), they'll need to have an HDMI 2 controller on the motherboard (which it's my understanding that no mac currently has anything better than HDMI 1.4 -- which gives 4k at 30hz max res).
