For those with issues, are you planning to keep the monitor and get a replacement through Dell warranty? Or are you planning to return the monitor?
I am thinking of returning and waiting for a revision. Also, I am expecting the price to drop a bit as well.
Mine is the 24inch version and it displayed all the symptoms everyone is discussing for the 30inch.
I organised for replacement on the 23rd of December, as it developed a dim section in the panel.
Anyway a very apologetic Dell CS, told me that the monitor won't be available till in the new year, with no eta and that it will be will be shipped direct from factory.
Who knows maybe Dell found a fault that need it to be rectified in the factory or potentially Australia was only allocated a few of these monitors.
Finally I got it the replacement on the 10th of January. I haven't tested the sleep issue on the new replacement, as I don't usually let my computer go to sleep.
But will update here if anyone is interested. Also is there a way knowing if it had a revision change?
I am planning on getting another 24 HD might wait if this is an hardware issue.
Just to add,..
Since my replacement arrived 4 days ago, I have had no 1/2 screen issue on logon page, Bios displays correctly on the 4k.
Dell 4k 24 inch on supplied mini DP cable, DP1.2 in the OSD menu, Asus GTX760 with the latest Nvidia driver (will update version)
Dell standard 24 inch premier color on DVI
i7 ivy bridge
C drive Samsung 840 pro SSD (OS only)
D drive Samsung 840 pro SSD (Adobe CC and LR only)
E drive LSI 9260-8i with 6 x WD RE drives in raid0 as scratch
I have the same problems. After calling the Dell Support, they told me to replace the monitor. Now I have to wait for a new one.
I am using a Dell UP3214Q (Rev. A00 Oct. 2013)on an EVGA NVIDIA GTX 780 TI ACX Classified and an ASUS Rampage IV Black Edition Mainboard.
I also have the problem that the monitor will not wake from sleep. Interestingly, if I power it off, then let it sleep, I can wake it up and *then* power it back on and all is good. EVA GeForce 780 (3GB), Dell-supplied DP cable, Windows 7 x64, GeForce drivers 331.82 WHQL.
I tried the 332.32 WHQL drivers and never saw the desktop: just black screens. If I use SST mode, everything seems happy, but switching to MST & 60Hz is when the trouble starts (which is, of course, how I want to use this monitor).
I was told today that getting monitor exchanges will not fix the issues. Nvidia told us that drivers after 327.xx will have issues. We are working with Nvidia on this. Roll back your driver to 327.xx. That should stop the blank screen and the 1/2 screen issue. Please test those 327.xx drivers.
