@desmond86: very interesting. So it seems AMD and nVidia have some work to do with their Windows drivers, but should now what is to be done given that it will be them making the OS X drivers as well.

I take it the resolutions you get in OS X are all 60Hz, correct?

Apple is making the drivers for both AMD and Nvidia but Nvidia also provides their own Web Driver.

If I remember correctly, I was offered 60Hz on all resolutions and even 75 Hz on lower resolutions on the Nvidia card.

I could not get the display to work at 60Hz on the AMD card, only at 30Hz. I will buy Nvidia card again in a few weeks and can give you a more precise answer then.

AMD's latest firepro driver now calls out the UP3214Q in the release notes:

Known Issues

Display port 1.2 instabilities on Dell UP3214Q display

Users reported success with the Catalyst Control Center 13.251.

Tomorrow i expect this monitor to arrive in my office... i saw a lot of ppl complain about 1/2 screen,not waking up and so on... i will see if i can get 001 revision at least...

For AMD graph card users, did any1 tried this as a solution - to make this monitor eyefinity and stuff

Well, i received monitor last night, it worked 5-6h(i imidalty swaped to 1.2 dp so i can have 60hz) , than problems started. It started to go to powersaving mode on random ... during my work, and during my game , than it shows half screen, etc. I also having problems waking monitor up from sleeping mode ( works only if u restart/shut down pc )... consider fact that i am using this for job( i am professional poker player , and i have a lot of money at tables during my sessions ) this is not acceptible ... i played session and it dropped in middle of it , making me lose at least 500$ for 2-3 minutes of not waking up ... i am returing tmrw this monitor and will ask for refund .

Its such a shame , this good product not to work properly.

And yes i have very serious rig in my office ( devil13 hd7990 gpu with possibility to have 5 monitors attached, support 1.2 and support mini dp and so on , i74960x, sabertooth x79 , intel ssd780 480gb, 4x4 kingston beast, seasonic 1000w psu , apc psu , and so on ) ... i have 4 monitors on table and never got problems before .

:/

can some1 at least tell us when we can have a01 revision ? i am living in eastern europe ( serbia ) and today i spoke with dell officials (official distro in serbia/belgrade) they can replace me monitor , but with same revision... so no point of changing for the same one :/

This is the USA Forum and we are in the USA. We cannot know the revision status of other countries. You just have to keep checking with them.

The past few driver releases from Nvidia appear to exhibit severe bug regression with the 32" display. I am experiencing the old half screen and blank screen issues consistently with every driver released since version 337.88. As a reminder, I'm running an EVGA GTX 780 Ti Classified.

Is anyone else experiencing this? I would post to the Nvidia forums but last time I crosslinked I was scolded by the Dell representative. Would like to see this resolved at some point during my (thus far wasted) 5 year warranty, but at the rate things are going I have little faith.

For ATI/AMD users , look like i found solution to make this monitor work ( at least for workspace )@60hz.

I did following:

-made clean 13.12 install (used DDP to unninstall all driver's) 

-after installation shutdown computer, w8 a while than turned on pc

-when monitor turn on / windows start, switch in monitor menu to displayport 1.2 to enable 60hz

-you will have split screen now (2monitors) , you need to use Catalyst Control Centar to enable  Eyefinity do exactly like on this link ( search for Important 4k Consideration http://www.tftcentral.co.uk/reviews/content/dell_up3214q.htm#calibration )

-after you successfully setup eyefinity , you will have ONE screen and u will not notice 2monitors/halfscreens/and other issues when u enable 1.2displayport @60hz

-after you restart your system, again you will get msg that displayport not working and resolution will change , you have to turn off displayport in monitor menu, than again to enable displayport and you will have 60hz native refresh rate with full 4k resolution and all works (without 2x screen/halfscreen and so on).

Note: everytime u restart your system u have to disable/enable dp in order to have 60hz , so my advise is not to restart pc if you dont have to ( i work for 6-7h i restart on my own , and return to work )

Note 2: This dont solve power/sleep mode issues , and if you play games , you will have power/sleep issues on random( for example when i start league of legends\fifa 2015 i dont have sleep power problems, when i turn CS : GO monitor show half screen and go to power mode every 2nd time ) . This tweak only enables you to work at 60hz .

Hope i helped a little.

note3: i just restarted pc few times, look like on every 2nd restart monitor bugs, first time i restarted it changed resolution and u have to manualy change in menu as i mentioned above, next time i restarted everything worked perfect, than again i restarted and it changed resolution, and again i restarted everything worked fine. So on every 2nd restart it broke.

I've filed a case with NVIDIA since they don't expose FHD and QHD resolutions and they told me there's a regression in the latest series of drivers that's going to be fixed in an upcoming release. You need to use the 337.61 or 337.88 drivers that still contain the fix. However, imho, I wouldn't accept the screen unless you get an A01 (NVIDIA also recommended I get the updated firmware and thus an A01). My A01 broke so I'm currently on the A00 but with intel drivers (no half screen so far but major sleep issues).

And the latest NVIDIA drivers work fine with the A01 revision (and drivers older than 337.61).

Has anyone tested the new Nvidia driver 344.11 with the UP3214Q on DP 1.2?

If yes, please post your revision (A00 or A01).
