Mac Pro Late 2013 and Samsung 4k monitor problem

I purchased the samsung UHD monitor as well, however when I connect it my maximum resolution option is 1080p for some reason. Anyone?

You should be able to get 4K @ 30 Hz over HDMI.

Everyone seems to be complaining about the tearing problem when using the display port. I have another problem. I am still using the HDMI at 30hz. The problem I notice is not tearing, but streaks in the display. Anyone else seeing this?

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?

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

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 ...

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 🙂

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,

Just because a 4k TV has a 60hz or better refresh rate doe not mean that it has a connector (i.e. displayport 1.2 only current way to connect a Mac) to support a computer pushing a 40k at 60hz signal.

Here are some good discussions. According to some commentators, no upgrade in cables is required for HDMI 2.0 and it MAY be possible for Apple to upgrade latest gen Macs (with Thunderbolt 2 + HDMI ports) to HDMI 2.0 via a firmware upgrade. But that is just speculation because Sony evidently upgraded their HDMI ports to ver 2.0 via firmware upgrade. It probably has to do with what HDMI chipset apple includes on the motherboards -- and Apple's willingness not to intentionally withhold HDMI 2.0 for future Macs (not that they have a history of dribbling out such upgrades so their customers have to upgrade constantly)...

Hi I'm curious I've tried the Samsung monitor with the mid 2012 macbook Pro and connected via the mini display to display cable the resolutions that are available are very low.

Any tips as to how to set it up.

Thanks for your help.

hi dmolrub

I don't seem to be able to get it working. I'm on a new Mac pro D500, 10.9.5, and I followed your sep by step guide, but it only seems to create a text edit file in System/Library/Displays/Overrides/DisplayVendorID-4c2d/ which is called the correct name, but with the extension ".saved" (DisplayProductID-b80.save) and no changes to my monitor (samsung). Any ideas?

I have not tried yet but I hope to have a second one soon. I have the D500's but I don't think it will be a problem to drive 2 of these monitors by assigning each monitor to its own Thunderbolt bus. And using Yosemite rather than Mavericks.

Now that the big box stores carry this monitor, it is easy to try and if it doesn't work, return the monitor.

It sounds like Yosemite will be released soon so the tearing problems will soon be a thing of the past.

Despite all the rightfully negative comments arousing from this thread I am off to purchase 2 of the Samsung UD590's.

I am a member of the highly unfortunate group who opted for the mid-range D500 cards not knowing that it would prevent me from actually using what is modern consumer-level 4k display technology.

In regards to the Yosemite update fix: Being in audio for the past 13 years I've learned not to update OS's until the time is right. Otherwise, a plethora of problems arise with my AU plugins in Logic & Ableton... I still may give it a try if there is a possibility that I can revert back to Mavericks.

All that aside, does anyone know the code-fix to drive dual Samsung UD590's to 50-54hz in Mavericks? Will SwitchResX and the code previously posted work for this dual monitor setup?

My cables won't arrive until Monday or Tuesday since they are sold out everywhere so I have some time to mess around with these in the meantime. Hoping I can drop the resolution (temporarily) so I can use 2x HDMI cables while I wait.

Hi,

Can you confirm if the tearing issue is fixed in the consumer release of Yosemite? I'm considering picking up an ASUS PB287Q and want to know if this issue still exists. Or if it is working normally now in Yosemite.

It'd be great if others chime in about their experience with these monitors and Yosemite too.
