Q: 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

    You used both cables?  Or do you mean that either can be used?  What native resolution are you running the monitor at?

    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.

    good hint SNP001 to test 10.10 on an external drive .... and I can confirm too: the "artifacts and flickering" on the right side of my Eizo screen are gone!

    now the dilemma starts ... artifacts or poor design?!

     

    other problem I got with Boot Camp that the monitor runs in 800x600'ish resolution but shows full ... but that doesn't belong here.

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

    I have the exact same issues as 60 Hz via a DP 1.2 cable with an Eizo EV3237 - the tearing on the right side of the screen after waking from sleep.

     

    Same problem on two different DP <> MDP 1.2 cables (high bitrate for 4K) - one is a factory cable from Eizo.

    Solutions - each one works on its own:

     

    - switch LCD off and on again

    - change resolution and change it back

    - change dekstop rotation in OS X prefs

     

    RUnning 10.10.1.

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

    Dear all, I think I have found a simply fix to the Mac Pro /Philips 288P issue. the screen is set to Display Port 1:1 at the factory all you need to do is:

     

    Get a good 1:2 cable

    Change the settings on the screen to 1:2 display port

     

    Thats it and it works perfectly.

     

    Happy days.

    Sorry to resusurrect an older thread but I've been having issues with my Samsung U32970Q and I used the display override that joevt posted but now my Mac Pro thinks I have a U28D590.. What part of the override tells OS X the name of the display?

    Hi there, and especially joevt,

     

    I've been reading the interesting many previous posts in order to find a solution to this situation:

     

    • Brand new Philips Brillance 288P 4K monitor
    • Macbook Air 13" from mid 2010 running OS X 10.6.8
    • NVIDIA GeForce 320M
    • Mini Display port cable to HDMI into the 288P Display

     

    At first I couldn't get the passed the 1080p, then I downloaded the SwitchResX application and could manage to get to 2560 x 1440 but only at 30hz which is causing me a real headache after 10min.

     

    I also have the Apple Cinema Display at home (the 288P is to put at my parents-in-law's) and on this one everything is fine...

     

    I would totally understand there is no way to push UHD in 4K with my old MBr and setup but why can't I just get the same resolution and refresh rate as on the Apple screen? Am I missing something?

     

    Thanks a lot for your help!

     

    Marc.

    Mack911-

     

    You can't do better with HDMI.

     

    If possible, use DisplayPort family.

    I have the Samsung U28D590D connected to my late 2013 MacBook Pro and could only get 3840x2160 @ 30Hz on OSX 10.10.2 through the HDMI port.  Connecting up to the Thunderbolt port with would not work.  After updating to 10.10.3 I decided to try the display port again and was very surprised and pleased to see that I'm now getting 3840x2160 @ 60Hz!  Problem fixed.
