All calibration measurements are done using SpectraCal’s CalMAN 5.1.2 software with a custom workflow. Measurements are done using a C6 colorimeter that is first profiled against an i1Pro spectrometer to ensure accurate results. There are two sets of targets we use. Pre-Calibration and our first calibration aim for 200 cd/m^2 with a sRGB gamut and a gamma of 2.2. This is a common real-world setting for a display. The final target changes the light level target to 80 cd/m^2 and the gamma curve to the tougher sRGB standard.

 

Pre-Calibration

Post-Calibration,
200 cd/m^2
Post-Calibration,
80 cd/m^2
White Level (cd/m^2) 201.4 199.1 79.8
Black Level (cd/m^2) 0.2477 0.2502 0.103
Contrast Ratio 813:1 796:1 775:1
Gamma (Average) 2.26 2.22 2.41
Color Temperature 6434K 6508K 6553K
Grayscale dE2000 2.97 0.64 0.63
Color Checker dE2000 1.69 0.52 0.50
Saturations dE2000 1.91 0.41 0.45

Pre-calibration measurements are made using the sRGB preset as most people will likely select it. Set for 200 cd/m2 of output there is a red tint to the grayscale. The gamma is off at 5% but the color tint causes the dE2000 for the grayscale to be in the visible range. Color errors are much better and aside from a few samples it is very acceptable. If the grayscale didn’t have this tint the pre-calibration numbers would be great.

Post-calibration this grayscale issue goes away and the colors improve as well. For both the 200 cd/m2 and the 80 cd/m2 calibrations the numbers improve by a large amount and the image is virtually perfect. There really isn’t anything to complain about, just that if you can calibrate the UP3214Q you will wind up with a virtually perfect image.

    I don't know what is considered by many as HiDPI but this monitor is most definitely not HiDPI at just 140 DPI! I know that most highend monitors are ~ 100 DPI and common one are even lower but I don't see why 140 DPI would be such a big deal. Are the Icons that much smaller? Are the alphanumeric character unreadable?

    I believe the the ridiculously low DPI of generations of monitor has made expectation of huge icons and lettering the norm and they are just not needed. You can see the icons and characters perfectly fine at 140DPI no scaling is needed!

    Yeah I think its just people set in their ways. Even when I had an out-dated prescription and saw worse than 20/20 I still would have no problem with that size. The only thing I can think of is that is just how most people have used computers and are stuck in their ways. I used 1600x1200 on a 17 inch CRT way back in the days (pre windows-2000) and soon after when I switched to linux I was 2560x1920 on a 22 inch CRT. It was even a bit blurry but it was still not a problem and that was 160 PPI. With a super sharp 140 PPI display why do people need scaling? I don't use scaling even on a 200 PPI+ display.

    Personally, I'd like to see a 39" 4K monitor, using the same VA panel in the Seiki TV but with a 60 Hz input. The Seiki TV is OK for productivity apps, but if you play any games or watch videos, as I do, then the low frame rate is a deal-breaker.

    A 39" monitor at 4K would provide an absolutely huge workspace - you would no longer need a multiple monitor setup. And the DPI isn't much higher than a standard 27" 2560x1440 monitor, so you don't need to use the Windows scaling that so many applications still don't do properly. (Microsoft really needs to do something about this - right now they seem content just to hope everyone eventually moves to Metro, which they aren't and won't.)

    Chris H. - does the Dell preset for Game exist? On my 24", the Game mode has less lag (by many milliseconds), with a tradeoff that the color is a bit too overdriven.

    May be UltraHD in comparison to a TV, but 138 DPI is something I would sneeze at. A 50% increase in pixel density compared to a standard 16:10 24" monitor with 94 DPI is not enough.

    Everyone should read this before purchasing this monitor: http://en.community.dell.com/support-forums/periph...

    You mention the usefulness of contrast over brightness in this instance. As LED monitors do lose a notable amount of brightness over time, are you able to re-test the brightness of a monitor that you have previously tested and recorded the numbers on and report the differences?

    I suspect over the long term having a monitor that can go brighter than needed may be more useful than suspected.

    It was looking quite decent, but that lag, wow, seems like a motion blur city.
  • cjl - Wednesday, April 2, 2014 - link

    Lag does not cause motion blur. Lag is how long a display takes to react to an input, and is usually (in the case of displays like this) caused by a delay in the image processing circuitry in the display itself. Motion blur on the other hand would be caused by a slow pixel response time (where the pixels themselves take a long time to change states after the display has already begun to refresh).

    I'm more looking for the 28" Dell one, much better price/performance for me. 600€ is nearly as much as I paid for my 1440p monitor not that long ago. Incredible.
