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!

I also just want to check and make sure, but has anyone had this issue with either the Samsung or Asus monitors? LG 34um95 Ultrawide Monitor Not Waking During Boot on 2013 MP

I have not experienced this issue with the Samsung. I have it connected with a 30" Apple Cinema Display and a 23" ACD And they all power up and wake up from sleep perfectly.

I have ordered an Asus PB287Q, and it should be arriving Thursday. I'll let everyone know how it works with my 6-Core Mac Pro with D500s.

The display is fine now at 3840 x 2160 in Yosemite.

Anyone have a good color calibration setting for this monitor?

Well seminolefans, at least we got someone's attention... hopefully it is not just a forum mod deleting things.

I hope people were subscribed and got the email so they can still read it!

Thanks for the update. Did you leave your color settings the same, or did you find the need to fine tune them? To me the color isn't as vibrant.

What monitor settings are you using? I find the greys are so bright, that they often blend in with the whites....

I have the same screen. See my earlier post. Running 10.10.1.

You can't do better with HDMI.

If possible, use DisplayPort family.

For me 10.10.3 doesn't solve problem with 60Hz. Have you done something different than usual or it showed up automatically after update? 2560x1440 resolution is enabled with hidpi mode?

There is still no solution for 2560x1440 with hidpi, right?

No, It appears, Apple cannot fix it. Still crashing. Starting to get angry here....

Somehow wondering about, why they do not just add some useful resolutions around 50Hz - everyone would be happy....
