So I figured out a work-around which fixes the 1/2 screen problem 100% of the time and the no screen problem 90% of the time. The key is to force a resolution change - that causes the graphic card to send out a signal which takes monitor out of power saving mode (or half screen mode).
The problem is how to do this when you have half or worse, no display at all? The answer is to create a hotkey to force the resolution change. The utility I found which does that (nice little freeware one) is called HRC (Hotkey resolution changers) and is available for free here: http://funk.eu/hrc/
I made two hotkeys using ctr-alt-F1 (set at 3840X2160) and ctrl-alt-F2 (set at 3840X1080). When I get a blank or half-screen, I first switch hit ctrl-alt-F2 and the screen will turn back on and both halves re-appear. Then you can switch back to normal resolution with ctrl-alt-F1.
Hope this helps! I hope dell addresses this issue - could easily be fixed via the dell display manager software and giving a hotkey which cycles the resolution back-and-forth automatically as a workaround to this annoying bug.
apart from that the monitor does not support scaling in MST mode
At this point, that's the only serious issue I'm having. I've *never* had the "half screen" issue so many people seem to be seeing (though it was hard rebooting my computer, that's largely alleviated now), but the scaling is an issue...30hz is kind of painful in games.
Can anyone comment on whether the lack of scaling in MST mode is due to a physical hardware limitation in the monitor, or if it's just a bug?
Also - does anyone know if AMD graphics cards will do software scaling? It appears nvidia won't.
I have been asked to pull all of this into excel. There are three items we need from each of you; monitor model video card operating system
Scan through this list and check for your username. Be sure that three items are in my list. If not, let me know so I can add it. Green means I have all the data. ===================
ABerlinger UP2414Q AMD W5000 FirePro Win8.1
aged_osprey UP3214Q Nvidia Titan
BelleTech UP3214Q AMD R9 290
BlippyCheese UP3214Q Nvidia EVGA GeForce GTX 780 Win8.1 Pro
DmitriyFS UP3214Q Gigabyte GV-NTITAN-6GD-B Win7 SP1 Pro x64
I contacted with Nvidia support, done what they asked me, gave them some system reports and received this answer: "... such issues could occur due to a corrupted firmware on the display"
If you haven't already, send Nvidia the report from "Entech Monitor Asset Manager" software (search online for it) - and also post it here.

So, you're suggesting to run a $3000 monitor sold to run at 60hz, to run it at 30hz like a $550 monitor?

It works for me. Did you try with 331.93 BETA as suggested back in January ?

Monitor is the same one as Sharp and Asus 321q
lcd panel, control board etc, all the same.
Asus had briefly the same issue and fixed it with a firmware update (user installable)
So, it rests with Dell, let's see if they are as good as Asus in customer support on a $3000 monitor
