Mac Pro Late 2013 and Samsung 4k monitor problem

I have the new Samsung 28" 4k screen (U28D590D) and it has tearing along the right edge when used with displayport. Any way to fix that? I tried different cables (all DisplayPort 1.2 complient) to be sure and have narrowed the issue to the Mac Pro. The HDMI works fine tho only @30hz so is a bit laggy in normal interaction. There is no way to turn on Multi-stream as indicated and I hope it isnt that this screen will never work.

Mac Pro, OS X Mavericks (10.9.2), Dual Fire Pro D700

Good news! I have this same issue running 10.9.5. But I installed the golden master (build 14A379b) of Yosemite tonight and my Samsung displays perfectly @60hz at all resolutions! FINALLY! Yosemite should be out in just a few more days so rest easy Samsung U28D590D owners! Relief is on the way!

That's good to hear. I believe the Asus PB287Q uses the same panel as that Samsung.


I have a LG 34UM95 currently, however I'm having an unsolvable and unacceptable Thunderbolt issue with it. And was thinking of possibly selling it and getting one or two of the Asus. True 4K will probably work better for my needs anyway.


It just seems like finding a completely compatible monitor for the Mac Pro is impossible unless you use one off Apple's list.

Why not just get the Samsung? Even when I had that distortion on the right-hand side under 10.9.5, I still thought the Samsung was stellar. But now that it is gone completely, I'm enjoying every single inch of it... literally! My only complaint is the stand. It's pretty flimsy and there's no VESA mounting in the rear, so you're forced to stay with the flimsy stand. Otherwise the display is truly stellar!

Cheers!

Hello,


I think it would be nice to have an overview which monitor is fully working at 3840x2160 60 Hz without problems

- No problems means: no flickering, artifacts, glitching or whatever you want to call it.

For Mac Pro running Yosemite os x 10.10

Connected on the thunderbolt - displayport

I would like to know if they work without tinkering around with special configuration programs or without changing any configuration files.


Example


Asus PB287Q

D300 GPUs Working / Not Working

D500 GPUs Working / Not Working

D700 GPUs Working / Not Working

Samsung 28D590D

D300 GPUs Working / Not Working

D500 GPUs Working / Not Working

D700 GPUs Working / Not Working


Please change the Bold text as you experience


Best Regards

Hello, i am using an iMac Late 2013 with NVIDIA GeForce GTX 780M 4096 MB, 3,4 GHz Intel Core i5 using display port


i had the u28 working on Mavericks with hidpi mode but only at 30Hz which was ok for me.

Now after updating to Yosemite i am not getting this mode any more, all i have left is 2560 *1440 which gives my kind of blurred text and one 1280 *720 (HiDPI) which is ridiculous because everything is way too large.



Anybody got a resolution to this , i would very much appreciate it.

I just tried my late 2013 iMac with the GTX 775M graphics. I got a mirror of my 2560*1440 but nothing greater with my Samsung monitor plugged into the thunderbolt port and into the display port 1.2 on the monitor. There doesn't appear to be any other options in the system preferences.


Maybe SwitchRes can help?

After install Yosemite my Asus PB287Q suddenly work like a charm, All the problems are gone, But after three days, The screen is turn to black (Monitor still working by using HDMI input) and show "No Signal" from Displayport,

Now, no matter what I try, It's just dead and even worse, I was call Apple technician regarding this issue, but no one can answer, is anybody know why?

Hi,


I'm wondering if anyone who has these monitors can open up their System Information, go under Graphics/Displays, and tell me if their display is detected as a Television? As I'm wondering if this is causing the issue I am having with boot.


Or, if you could tell me if you can see the Apple boot splash during boot, and/or the FileVault password entry screen?


Thanks

Some times the screen will not light up even when the blinking blue "sleep" light is on. I have to reach behind it and turn it on by pressing the joystick control. Then it takes me to the login screen. This happens when I reboot.


I usually leave the Mac Pro on and let the monitor go to sleep, A mouse click generally wakes it up.


I haven't seen the white boot up screen with apple logo since I got my Samsung monitor.


When I first got my Mac Pro, I was using a Acer monitor (with 1/4 the resolution) using the HDMI port and the monitor had no trouble displaying the boot up screens.

To be fair to Apple, these 4K SST monitors did not exist when the Mac Pro 2013 was introduced. I don't think Apple sees much money in adding features to a product that you already bought. It's not even adding a feature, since there is a working 4K solution already (but it's not these SST monitors). You drank the Kool-Aid so Apple doesn't need to do any more.


Whether Apple fixes this depends on what your customer satisfaction is worth to them or how many Mac Pro customers they are losing because of this problem. On the other hand, this might be incentive for existing owners to buy the next generation of Mac Pro - if Apple makes one. When they introduced the new 5K iMac, the keynote event mentioned/showed pictures of all the other Macs except the Mac Pro. Does that make it the redheaded stepchild or was the event not pro centered?


To fix this problem Apple would probably need to make some kind of EFI update either for the computer or the graphics cards. Maybe they have a reason for not making an update available. Someone might be able to figure out how to change the firmware of the graphics card to force booting into a resolution that works at startup if they can't figure out how to boot at full resolution.

after putting some money aside, I finally made the move to invest in a 4K Display by EIZO and I have the same issue with the weird artifacts on the right side of my screen.

running on a laggy HDMI connection at the moment which is not a longterm solution because I earn my money in creating animations and 30Hz will not do.

I did not update to 10.10 and would like to find a confirmation if this solves the problem and to run the monitor on 3840x2160@60Hz at the same time?!


if not ... what other solutions would you guys suggest (with a BIG thanks in advance!)?


my setup:

EIZO Flexscan EV3237 4K monitor using a "clicktronic" DisplayPort to MiniDisplayPort adapter cable.

nMP (late 2013 - MacPro6,1 - AMD FirePro D700)

OS X 10.9.5 (13F34)
