This is a byproduct of how MST works, or how the videocard deals with MST and lower resolutions.
To work around it, tell the monitor to disable DP1.2. Then you will get proper scaling. You will lose 60hz at 2160p, but 1920x1200 and lower will get 60 hz and will be scaled by the monitor. (On my system I cannot get 60 hz at 2560x1440 - probably a driver limitation of NVIDIA + Windows).
Are you sure about this? I remember running 1080p full screen DP1.2 on OSX.
Btw, I will probably end up selling the Dell UP2414Q since I found a great priced monitor:

40" inch VA panel with pretty good response time on the spec at similar price for what I paid for this 24" inch display.
It will be out in End of October or later. It remains to be seen if it will use MST or SST.
I just got mine a couple of days ago. I am not having any issues so far and it is version A00 manufactured in Jan. 2014. The firmware version is 1019 so I'm not sure what the A01 is but I know the first version for A00 was 1003.
I connected both DP 1.2 and HDMI cables so when using the monitor I am on DP and when I want to get into the bios I log off and change inputs to HDMI and reboot. Then I see the bios and all of the post processes. Then I switch back to DP when I get to the login on Win 8.1.
I am using the Nvidia 344.48 drivers on SLI Titans. Let me know if you want full system specs. This is the most spectacular display I have ever had or seen. All my games run on Ultra settings with v-sync enabled and they run like butter. I am coming from a U3011 Dell monitor. The Ultrasharp monitors while being expensive have never had any backlight bleeding or dead/bright pixels for me.
Hopefully this one will keep running good and Dell to start allowing people to flash their firmwares. It would be nothing for them to release the FW file and a flash utility.
How is dell's return policy with the UP3214Q in sweden? I had it now for 5 months and it just gets worse and worse! just like my old U2711
Cant enable DisplayPort 1.2 there is always SOME problem happening and all those sleep mode bugs drives me nuts!
And it`s also impossible to use a USB 3.0 Cable attached to it, then it takes forever for the PC to boot up or it just restarts time after time or just goes blank or in to windows repair mode, the USB with cardreader was one big Selling Point for me as I have the PC in Another room from the monitor.
Can one get the Money back or do you get a refurbished one???
Refunds are only allowed within the first 30 days from the Dell invoice date. All exchanges done outside of the first 30 days are refurbished. You will need to contact Dell Technical Support in your country to arrange the exchange.
Are all the problem fixed, the USB 3.0 and the sleep mode bug? Enable DisplayPort 1.2 could maybe be fixed with better graphic drivers I hope. Anyone else have problem with using a USB 3.0 cable to the display? To me it really messes up the entire PC with both Win 8.1 and Win 7. Or is there a some setting in bios that would fix it?
I have bought UP2414Q at 14 November 2014 in TURKEY.Problem is my A00,and can't 3840x2160 60 Hz.
Contact Turkey Dell but not change A01.Please help me.
You must install the latest video card driver. Also test with DP1.2 disabled. No one can "choose" the revision. But a used monitor exchange should automatically get you an A01. A new exchange will get you an A00.
