humba, I could never get 2560x1440 to work at 60 hz either.
However, in another forum I read this:
The monitor will happily accept 2560x1440 in DP 1.1 mode and do 60Hz, I am surprised the nvidia drivers are being weird but that is windows for you... In linux no problem doing 2560x1440 at 60Hz in both SST or MST modes (in MST mode giving it 2x 1280x1440 halves).
So this may be an EDID or NVIDIA windows driver issue. Myself, I couldn't get it to work even with defining a custom resolution in the NVIDIA control panel nor could I get it to work with ToastyX's CRU (Custom Resolution Utilty). :(
I'm a mac user. Luckily I can use 2560x1440 60hz on scaling mode which looks great. It kind of defeats the purpose to scale down a 4k display like that. Hopefully, this will be added to windows too.
I've got a rev. A00 and a lot of what I have been experiencing (mostly) are post issues. However when I boot into Windows with the monitor off I turn back on the monitor and works as expected.
Intel has some new graphic drivers out now "v10.18.10.3910" now I can get 3840x2140 in 60hz for the first time with my Dell UP3214Q see links to the drivers on the bottom of this page https://communities.intel.com/thread/53655
I sold my Nvidia 660Ti and bought AMD 280, have no issues with cold boot or restart. I experience issues with wake from sleep only, but even that is occasionally.
Did any problem with the dell UP3214Q monitor get fixed with rev01 ? like the Wake up problem? is there a rev02 coming out soon thats worth waiting for???
I still get a wake up issue on mac pro but rarely. I've owned this monitor for about 3 weeks and it only has happened twice so far. The fix is basically just turn off the monitor for about 10 seconds and turn it back on. It's annoying but it's not too bad given the frequency of occurrence.
Hello, I am using the UP3214Q Rev A01. There is no known issue for me; no wake up issue, no half screen issue, no boot display Problem. All works fine with A01, but not with A00 MM69
madmarc69! What graphic card are you having? can you get 3840x2160/60P without any problems or bugs? Are you able to play 4k HEVC/H.265 video files completely smoothly ? like the ones here...... http://demo-uhd3d.com/
@desmond86: it is mostly an issue with nVidia cards, though not only - you'll find the occasional AMD affected user as well in this thread. I've personally experienced it in an ATI card, after switching OS and driver. Those of us who have an intel card, have yet other issues to deal with.
Bottom line, the whole thing is still in beta, and we're nearing the 1 year point of this screen's release. Dell now coming out with a 5K screen using stiched displays yet again, seems a recipe for disaster given the current state of affairs.
And they're still shipping A00 screens, at least here in Europe (I got a new exchange.. it came as an A00 and of course has the usual issues).
But given that you have AMD and no issues, I'm wondering: do you get 2560x1440 and 1920x1080 at 60Hz in DP 1.2 mode? If the half screen/sleep issues are sorted, 2560x1440@60 is what I really want to run my screen when gaming as I don't have SLI to keep up with the full resolution.

I have done some tests today and seems there is more solutions:
When I turn off CSM in the motherboard BIOS options, it shows picture during POST time on DP 1.2
When I connect both DP and HDMI cable from the monitor to the Nvidia GPU and use DP 1.2 it also seems to show picture on every POST.
Edit: I was wrong about HDMI. It seemed to work first but I realized that it does not.
But setting CSM to off still seems to work.

I sold my Nvidia 660Ti and bought AMD 280, have no issues with cold boot or restart. I experience issues with wake from sleep only, but even that is occasionally.
ASUS Z87 Gryphon, ASUS R9280-DC2T-3GD5.
So this seems to be a NVIDIA issue?
