Oct 20, 2014 2:34 PM in response to rpalacioby Moesti001,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

Oct 20, 2014 5:02 PM in response to Moesti001by The_Dark_Passenger,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.

Oct 21, 2014 5:57 AM in response to The_Dark_Passengerby Landci,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.

Oct 21, 2014 9:25 AM in response to Landciby PB_NB,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?

Oct 21, 2014 9:33 AM in response to Landciby PB_NB,It looks like the iMac's don't have Thunderbolt 2 ports. Maybe there is a firmware update somewhere to bump it up. Until then, you won't be able to run the monitor at optimal resolution and frequency.

Oct 22, 2014 4:45 AM in response to Moesti001by ttppee,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?

Oct 22, 2014 7:08 AM in response to ttppeeby The_Dark_Passenger,If you have another computer you can connect it to via DisplayPort, I'd start there and see if it works. If not, then it sounds like something just broke with the monitor and you should contact Asus.

Oct 23, 2014 12:46 PM in response to digitalcolemanby Simon Chan1,Mac Pro (Late 2013)
6-Core
D500
Samsung 4k U28D590 Display
The display is fine now at 3840 x 2160 in Yosemite.
Anyone have a good color calibration setting for this monitor?

Oct 23, 2014 1:48 PM in response to digitalcolemanby The_Dark_Passenger,Just hooked up my Asus PB287Q, and can report that it is working with my Late 2013 6-Core Mac Pro with D500s, and does not have the tearing issue while running at the full 3840x2160@60Hz. However, I am still having the boot issue as I was with my LG 34UM95. It appears to be an issue with my Mac, and possibly not the LG. I will have to contact Apple and see what they can do as this pretty much confirms a hardware issue with my Mac Pro.

Oct 24, 2014 5:47 AM in response to digitalcolemanby The_Dark_Passenger,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

Oct 24, 2014 8:21 AM in response to The_Dark_Passengerby EdAnuff,Interesting you should mention that. I just noticed last night that the display info shows "Television: Yes" in the System Information: Graphics/Displays. I used the technique here to Force RGB Mode and the script from here to create an EDID override file so it wouldn't report as a television. It didn't have any visible differences to the display with the new EDID, so I put back the original EDID file. Also, I'd also noticed with this monitor that it doesn't display until it gets to the login screen and, for example, if I hold down the option key to boot off another volume, it stays dark. This behavior continues with the custom EDID, so I don't think it's related to the television identification.

Oct 24, 2014 8:35 AM in response to EdAnuffby The_Dark_Passenger,Thank you for your response. I called AppleCare, and the rep had me schedule a Genius Bar appointment. I'm taking my Mac Pro in Wednesday, and I'll let everyone know what they say.
If anyone else is having this issue though, please post about it.
Thanks

Oct 24, 2014 8:36 AM in response to PB_NBby The_Dark_Passenger,Thanks, does your monitor remain blank during boot, or does it display the boot splash and/or FileVault password entry screen. Also, is this the only monitor you have connected?
