Dell UP3214Q Review
by Chris Heinonen on April 1, 2014 12:00 AM ESTUsing the Leo Bodnar lag tester, I measure 47ms of lag on the UP3214Q using a 1080p signal. Without a game mode or anything else to speed up this processing, this is fairly slow. Most people probably won’t be playing many games at native UltraHD resolutions due to the graphics hardware required so measuring a non-native resolution signal, while never ideal, is probably closer to a real world situation here. For many people this will be too slow for gaming. This measurement is also done over HDMI, while almost everyone will use DisplayPort with this monitor to get 60 Hz, so that is another variable that might be different as well.
As a 32” display the UP3214Q is going to use power, and it consumes a decent amount. With the backlight at minimum is consumes 42 watts, and that climbs to 104 watts at maximum backlight. However this power use is still below the 30” Nixeus display that was recently reviewed, and even the 27” NEC PA271W professional display. The UP3214Q is less power efficient than either of those displays as they both have a higher maximum and minimum light output, even with the smaller screens.
The color gamut data has the same issue as the AdobeRGB data. A bug in the calibration has caused the gamut numbers to be off, so I’m reporting two different results. The one from my calibration is 82.7% of the AdobeRGB gamut. Using the included Dell ICC profile, it has 102.5% of the AdobeRGB gamut. Since the pre-calibration numbers appear to support the Dell ICC profile, I will say that the Dell UP3214Q supports the full AdobeRGB gamut as the specs say.

I'm not sure this is right. Companies usually are making and testing IP while a standard is in the works. In some cases they're out before the standard is done.cheinonen - Tuesday, April 1, 2014 - link
This is correct. There is currently no full HDMI 2.0 silicon out there that I'm aware of, and since the Dell started shipping last fall it certainly didn't have access to it then. There are currently devices shipping that claim "HDMI 2.0" support in the AV world, but that isn't full HDMI 2.0. It is support for 4:2:0 chroma subsampling, which is part of the HDMI 2.0 spec, and enabled UltraHD resolution at 60 Hz. Since computers don't use chroma subsampling, this isn't relevant and there is no HDMI 2.0 silicon right now.Penti - Tuesday, April 1, 2014 - link
Not even Maxwell can output it, so what sources are you suppose to use?BMNify - Tuesday, April 1, 2014 - link
where you get that idea from , its false you need a GeForce 600 "Kepler" graphics card or newer to drive a display up to 4096 x 2160.hell, even the ChromeOS guys have merged this linux UHD patch in to their tree now...so intel Haswell/Iris Graphics work at "UHD-1" 3840x2160P if you are not gaming http://lists.x.org/archives/xorg-devel/2014-Januar...

You can do that resolution at 24 Hz, or 3840x2160 at 30 Hz, but you can't do it at 60 Hz without MST right now. HDMI 2.0 allows it at 60 Hz but that isn't available yet on a product.Penti - Tuesday, April 1, 2014 - link
I was speaking about 600MHz HDMI not ~300MHz. 300MHz HDMI has been around since GCN 1.0 and Kepler. It's also available in Haswell, works fine in Windows, OS X or GNU/Linux at that res, but that limits it's to 30Hz for 3840x2160. That's not HDMI 2.0 specs. You can't use anything else than DisplayPort for 60Hz 4k/UHD. DisplayPort-receivers only do that on MST too. You need two 300MHz HDMI-ports to do UHD @ 60Hz. So gaming in UHD with HDMI is out regardless of gpu/source.Maxwell doesn't do H.265/HEVC for that matter either. You only need ~300MHz HDMI 1.4 to do 4096x2160 @ 24Hz. Not HDMI 2.0, that can do it @ 60Hz.

As far as things that still aren't there, I'd throw in color space (both gamut and bit depth) as well. Official UHDTV (see Rec. 2020), beyond the resolution standards bumping to 4K or 8K, also at last features a significantly larger color space and also the depth necessary to go with it (either 10-bit or 12-bit). That's another marquee feature of HDMI 2.0, 12-bit 4:2:2 4K@60fps. Without the increase depth a wider gamut isn't a straight upgrade since the delta between colors increases too, 8-bit AdobeRGB say isn't a clear superset of 8-bit sRGB. It's exciting that as well as HiDPI we'll finally see an industry wide shift to a color space that will be a strict improvement and is large enough to basically be "done" as far as human vision.There's still a lot more pieces needed on the PC side though, including both hardware (video cards, interconnect) and OS/applications. High DPI is slowly improving, but even Apple has slipped a bit in terms of color management and support. That said, given the economies of scale that'll come with the general UHDTV push the market pressure should be there at least.

Did you test it on a Windows computer other than the one you pictured? Because that one is 8.0, not 8.1 which added multi-DPI support.datobin1 - Tuesday, April 1, 2014 - link
Correct, 8.0 has static scaling across all displays. 8.1 introduced different scaling for each display.This works very well for surface pros that are docked. It will scale the surface pro display at 150% and the extra monitors at 100%. If you move a window between the displays the screen with the majority of the window will decide the scaling for that window. As you pull it from one screen to the next you will see the window change its scaling factor.

Yes, I tested with both Windows 8.0 and 8.1. I just happened to have rebooted into Windows 8.0 when I took the photos but I tested both.
