UP3214Q/UP2414Q - 1/2 screen issue and/or No picture after powering off, then on

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).

344.11 works fine on my A00.

I have NVIDIA MSI GTX 970 now and there is no cold booting issues with UP2414Q :D

I'm currently running an EVGA 780 Ti Classified with my UP3214Q (revision A00) at 3840x2160, 60 Hz/DP 1.2, with the latest Nvidia drivers published, 344.11. Seems to have corrected the half-screen issues again so far, however I am still experiencing issues bringing the display out of standby.

I'm required to manually power off the display, wait a few seconds, and power it back on. This causes all of my windows to mash up in the upper-left corner of the screen.

Is anyone running a Mac Pro successfully? 

I am running a late 2013 Mac Pro with Dual D700, OSX 10.9.5 (3840x2160x60hz). Monitor is A00. No problems.

Same monitor on EVGA Titan SLI, does not wake up from sleep, but no longer has half screen issue. Haven't tested with the PC for a long time - given up on this monitor on Windows. 

@prenetic: that seems to be the normal behavior for an A00 revision screen - I have the same with NVidia and intel GFX cards. The A01 will make things better in my experience (I've had both A00 and A01).

Those that have a MAC, can you run 2560x1440@60 in MST mode? Here's what NVIDIA had to say on the issue of 2560x1440 on Windows:

We look into the 2560x1440 resolution and this appears to be a limitation on the monitor which is based on the Sharp/ASUS panel. According to development the 4K tiled based Sharp/ASUS panel has 2 operation mode: MST and SST. In MST mode, due to their firmware limitation, the monitor scalar is disabled even the source (GPU) only sends 1-stream (e.g. 2560x1440x60Hz). So in MST mode the lower-res 16:9 mode like 2560x1440 are not supported. The firmware limitation was fixed with the newer version firmware from STMicro but Sharp/ASUS didn't adopt it. When the panel is switched to SST mode (by OSD control), the monitor scaler is enabled so 2560x1440x60Hz is physically support. But since 2560x1440x60Hz is not exposed by the EDID, NVIDIA GPU driver can only make 2560x1440x30Hz because it can be stretched to 4K2K30Hz.

So, it seems to be an A02 with the revised scaler firmware is in order to finally make this screen do what it's supposed to (and on the Dell end, they also need to update the EDID).

@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?

I haven't had time to get my GTX 970 running on OSX.

But in Windows I now get:

640 x 480 x 32 @ 60Hz
720 x 480 x 32 @ 60Hz
720 x 576 x 32 @ 60Hz
800 x 600 x 32 @ 60Hz
1280 x 720 x 32 @ 60Hz
1024 x 768 x 32 @ 60Hz
1280 x 768 x 32 @ 60Hz
1360 x 768 x 32 @ 60Hz
1366 x 768 x 32 @ 60Hz
1280 x 800 x 32 @ 60Hz
1152 x 864 x 32 @ 60Hz
1600 x 900 x 32 @ 60Hz
1280 x 960 x 32 @ 60Hz
1280 x 1024 x 32 @ 60Hz
1600 x 1024 x 32 @ 60Hz
1680 x 1050 x 32 @ 60Hz
1920 x 1080 x 32 @ 60Hz
1600 x 1200 x 32 @ 60Hz
1920 x 1200 x 32 @ 60Hz
1920 x 1440 x 32 @ 60Hz
2560 x 1440 x 32 @ 60Hz
3840 x 1440 x 32 @ 60Hz
2048 x 1536 x 32 @ 60Hz
2560 x 1600 x 32 @ 60Hz
1920 x 2160 x 32 @ 60Hz
3840 x 2160 x 32 @ 60Hz

It seems that Nvidia has solved all 4K issues. I have no cold booting, wake from sleep or half screen issues. And now I have all kinds of resolutions available as it should be.

That's great!

@Desmond86

So you are saying with the 970 you have no issues in windows?

Can I ask:

• Which make/model of 970
• Driver version
• Monitor revision
• No issues including not coming out of standby, requiring power cycle

Unrelated, for me the latest 344.11 drivers still have the standby issue.

GPU: MSI GTX 970

Driver: 344.11

Revision: A01

I have not experienced any issue of the monitor not coming out of standby and requiring power cycle.
