Monitor = UP2414Q
Video card = Sapphire R9 270
Cable = Dell mDP to DP
Computer = i5 CPU, 32GB
Operating System = Windows 7 64bit (latest drivers, bios etc.)
Display set to 3840x2160 - DP 1.2
No other monitors, video cards or associated drivers are installed.
Monitor is brand new. I have 30 years of experience, building, programming, administering a huge variety of PC systems. I know the difference between hardware, BIOS, firmware, drivers. etc. About half the time, the monitor will not properly resume from the computer being asleep, or from a warm or cold reboot of the system, i.e. The monitor will need to be powered off and powered back on for the display to resume, and/or the display will resume in an incorrect resolution and the AMD video card drivers will display one of the following messages:
1) "The system as detected a problem with the connection between your computer and the displayport display the will prevent you from using the highest resolutions and/or refresh rates..."
or
2) "The system has detected and link failure and cannot set the requested resolution on your displayport display..."
Since the display will often be blank during reboot (no BIOS messages displayed, monitor power-off/power-on required), before windows has started, it does not have anything to do with Windows, drivers or any other software. This points to a hardware and/or firmware/video card bios issue between the video card and monitor. Correct DP 1.2 communication is not occuring consistently.
I am waiting for the arrival of a new accell displayport 1.2 cable that I've ordered to see if that helps.
Please advise what video cards have been tested with this monitor to work correctly using 3840x2160 60hz, DP 1.2.
Please advise if there is a monitor firmware update available to address this issue.
Please advise what other steps I can take to resolve the issue.
It works correctly on my setup.

Another Dell 2413hm connected via MSI GD80 HDMI. I had issues in December, not sure if this was solved or not, but I haven't gotten around to connecting both monitors to GTX.
Thanks ip6,
So you have "1.2" mode selected in the Dell monitor settings menu? (Default setting is 1.1 - you get 3840x2160 but it's at 30hz)
Have you run successfully without the second monitor/card - just the UP2414Q at 1.2?
Does your system "sleep" or "hibernate"?
What were the issues you had earlier?
Thanks for any additional info.
Hi yes,
set to 1.2 in osd
windows verify 60hz
and no half screen logon issues.
no wakeup issues from turning off monitor or sleeping.

Check the label on rear/bottom. The team is investigating this. For now, can you set it to DP1.1/30Hz/3840x2160 so you do not have to deal with the issues while this is being worked?
