UP3214Q no scaling and no 16:9 resolution between 1920x1080 and 3840x2160?
Since the full 4K resolution is a bit too much to ask from my poor NVidia GTX780TI (at least at high detail level), I wanted to reduce the resolution somewhat when playing games. I found, however, that there's not one single resolution between 1920x1080 and 3840x2160 that has the proper aspect ratio. Every high res Dell Model I've previously owned (WFP-3007, WFP-3008, U3011, U3014) has supported resolutions with proper aspect ratio at less than display resolution (e.g. 1680x1050 or 1920x1200), so what happened there? Going below 1920x1080 I can once again find resolutions at the proper aspect ratio (e.g. 1600x900) Also.. if I set Windows to 1920x1080, this will get me one tiny picture at the center of the screen filling just one quarter of the screen real-estate. Since the screen is filled out during the boot process (BIOS, Windows startup screen), I think it can handle lower than native resolutions just fine, yet no amount of tinkering in the OSD menu (I tried al the values in Display Settings => Aspect Ratio) managed to correct the issue. I could of course ask my GFX card to perform scaling, but I'm left wondering why once I'm logged into Windows, the only way to get the picture to fill the full screen is at native resolution.

Aside from the monitor's native resolution, resolutions are really the responsibility of the display driver. Since you are using an NVidia display driver, you should have a custom resolution option in the NV control panel (usually under Display > Change resolution) where you can create a 16:9 2560x1440, which the UP3214Q will render edge-to-edge.

That's too bad. I was able to run at 2560x1440 edge-to-edge over DP using a GTX670, but I didn't try any other cards or configurations.

Hi, no you can, at least with a GTX 580 connected via HDMI. DP is 1.1a. I just received my DELL UP3214Q today. Connected to a GTX 580 (don't have time yet to unbox and install the 2 780 TI I also have. Launch NVIDIA Control Panel > Display > Change resolution > Customize Create Custom Resolution. I chose the max resolution for GTX 580 : 2560 x 1600 at 60 Hz. Works fine. I suppose it should also work with a 780 TI. Will try when I have time to install the 2. Was worried when I read this post, would have been disappointed if it didn't work. Hope this helps you :-)

sorry, cleartype, not true type.
text is also very sharper at max resolution when you don't customize in NVIDIA control panel, that is 1900 x 1200

swamped207 & Tasmanie,
What nvidia driver version are you running? Maybe ssteiner78 has a different driver loaded?

text is not very sharp with GTX 580 at 2560 x 1600, much sharper with the same card and same resolution on my DELL U3011
tried interlaced and progressive

Well (posting under my real account now... finally managed to get it registered) - there's one CRUCIAL difference between your rig and mine. Mine runs at DP 1.2. Yours at 1.1. Just for fun, I went back to DP 1.1 - and lo behold... I can set custom resolutions like 2560x1440 (also very blurry here), the picture is full screen in any resolution, and all the other nags and issues are also gone (all posted here under the ssteiner78 account). I can power off the display and power it on again and I get a picture (or if the machine shut off the video signal due to inactivity, I move the mouse and the picture is back), and I've yet to see a split / half picture on the login screen and I get full res picture on my Brix machine - if it ran at 60Hz I'd be a happy camper.
It seems that DP 1.2 mode is a different beast altogether.
I'm running the same nvidia driver release as Tasmanie by the way.
@edit: and I just learned that the Radeon HD 6000 series also does DP1.2...so I have a third machine to test with.

So, a test on the HD6970 (downloaded and installed drivers 13-12_win7_win8_64_dd_ccc_whql.exe), shows the picture: switching to DP 1.2 the computer boots up to half the display black (starting at login screen, before that it's full screen), and the res set to 1920x2160. I could change it to 3840x2160 which changed nothing. I hard to hard shut-off (long press of the power button) to turn the display off, then back on. At that time, I could use the full resolution. Things are still very much off though - I have hardly any resolution to chose from (after 3840x2160 I have 1920x2160 (even recommended resolution), along with the following oddball resolutions:
1856x1392
1800x1440
1792x1344
1152x864
Switching back to 1920x2160 gets me 1920x2160 filling the left half of the screen, and for some reason, the screen is automatically duplicated to the right. (note that on DP 1.1 I get a lot more resolutions to chose from).
Power off and back on seems to work on the HD6970 - I don't have to reboot to get my picture back like when connected to the other cards. I'll report back on sleep behavior.
But I have to ask - what were the tests performed with this screen? I feel either I have a bad screen, or this screen only works properly in very restricted scenarios. I've now gone through three different setups, none of which is problem free.
