Mac Pro Late 2013 and Samsung 4k monitor problem

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.

I am on a macbook pro 13inch mid 2014 and managed to get the U28D590 working for a 1920x1080 retina resolution (3840x2160 real resolution).

After upgrading to El Capitan, I lost the ability to do the same.

I disabled SIP to move the Display file profile where it should be.

That works and the file is valid however the setup that I had working seems to be ignored now.

Right now I am stuck at 2560x1440 (from what the OSD information tells me on the U28D590).

Current file:

MacBook-Pro:~$ plutil /System/Library/Displays/Contents/Resources/Overrides/DisplayVendorID-4c2d/Disp layProductID-b80

/System/Library/Displays/Contents/Resources/Overrides/DisplayVendorID-4c2d/Displ ayProductID-b80: OK

MacBook-Pro:~$ more /System/Library/Displays/Contents/Resources/Overrides/DisplayVendorID-4c2d/Disp layProductID-b80

I have tried enabling other resolutions by modifying the Display file above and but the monitor does not want to go beyong 2560x1440 (from the OSD).

Has anybody got that screen showing a 1920x1080 retina resolution on El Capitan?

Thanks.

borisnet-

what connection method are you using for this display? it can be tricky to get more than 1920 by 10180 out of an HDMI connection.

Mini DisplayPort (ThunderBolt subset) to Displayport should give you the best choices of resolutions.

Hi Grant,

There is indeed no way to get what I want to do over HDMI. So I confirm I had the setup working on Yosemite in a dual U28D590 monitor setup both connected with displayport 1.2.

What I am trying to understand is what changed in El Capitan preventing me to just reuse the Display plist file I had for this kind of screen as right now it simply does not work following the upgrade to El Capitan

Hi-

Where does this file go to get the desired resolution? i'm getting 4k at 60 hz with mavericks use SwitchResX but there is a small tearing anomaly down the middle of the screen. Is my only hope to upgrade to Yosemite? Thanks for any advice.

So I've just dug into this thread and have gotten SwichResX working with my late 2013 Mac Pro, AMD FirePro D500 3072 MB video card, Samsung UD970Q monitor.

Successfully got it running on DisplayPort 1.2, 3008x1692 at 50Hz.

Now I want to play with scaled resolutions (HiDPI looks nicer). How can I find the EDID of this monitor and how can I create this type of info for that EDID?

Thanks all for your amazing knowledge and detective work.

50 Hz (442.00 MHz):

54 Hz (478.50 MHz):

55 Hz (487.50 MHz):

56 Hz (496.75 MHz):

57 Hz (505.75 MHz):

Joevt - About a year and a half later I am running into the exact same problems with my external 4K connected to an El Capitan 13" rMBP. I was able to create a custom scaled resolution of 2560*1440 but it is at 60 hz.

If it is not too much work, could you advise how you would change the EDID below to have a native refresh rate of 30 hz rather than 60 hz? I cannot run any custom resolutions higher than 30 hz.

Hi all,

I have an issue with my MacPro Late 2013. Currently its connect to a Samsung UHD TV (40hu7000) and my mouse and keyboard is slightly laggy. I'm running on Yosemite, with apple Bluetooth keyboard and a Logitech Bluetooth mouse G602.
Same UHD TV works great with my MBP 2015 with the keyboard and mouse.

Please help, using the Mac Pro with this mini lag is such a pain.

Can't find this setting in Samsung display menu setting!

Wish someone can find the way to slove the problem!

I have updated to the Beta 13D55 and it is still an issue.
