Dell UltraSharp 24 Ultra HD Monitor: The $1300 UP2414Q

Measurement And Calibration Methodology: How We Test

To measure and calibrate monitors, we use an i1Pro spectrophotometer, a Spectracal C6 colorimeter, and version 5.2.0.1374 of SpectraCal’s CalMAN software.

For patterns, we employ an AccuPel DVG-5000 video signal generator. This approach removes video cards and drivers from the signal chain, allowing the display to receive true reference patterns. Connections are made via HDMI.

The AccuPel DVG-5000 is capable of generating all types of video signals at any resolution and refresh rate up to 1920x1080 at 60 Hz. It can also display motion patterns to evaluate a monitor's video processing capabilities, with 3D patterns available in every format. This allows us to measure color and grayscale performance, crosstalk, and ghosting in 3D content via the 3D glasses.

The i1Pro is placed at the center of the screen (unless we’re measuring uniformity) and sealed against it to block out any ambient light. The Accupel pattern generator (bottom left) is controlled via USB by CalMAN, which is running on the Dell XPS laptop on the right.

Our version of CalMAN Ultimate allows me to design all of the screens and workflows to best suit the purpose at hand. To that end, we’ve created a display review workflow from scratch. This way, we can be sure and collect all the necessary data with a concise and efficient set of measurements.

The charts show us the RGB levels, gamma response, and Delta E error for every brightness point from zero to 100 percent. The table shows us the raw data for each measurement. And the area in the upper-left tells us luminance, average gamma, Delta E, and contrast ratio. The individual charts can be copied to the Windows clipboard to easily create graphics for our reviews.

Every primary and secondary color is measured at 20-, 40-, 60-, 80-, and 100-percent saturation. The color saturation level is simply the distance from the white point on the CIE chart. You can see the targets moving out from white in a straight line. The further a point is from center, the greater the saturation until you hit 100 percent at the edge of the gamut triangle. This shows us the display’s response at a cross-section of color points. Many monitors score well when only the 100-percent saturations are measured. Hitting the targets at the lower saturations is more difficult, and factors into our average Delta E value (which explains why our Delta E values are sometimes higher than those reported by other publications).

    This is a joke right? Dell making yet another mockery of the monitor market.

    Why oh why when you can get the latest 10-bit AH-IPS technology in the 2560 x 1600 30" Crossover Black Tune 30x for $700?

    You obviously miss the point of this monitor. The whole point of a 24" 4K monitor is the pixel density. The fact that it's 8-bit and not 10-bit probably isn't going to bother a whole ton of people and if 4K and 10-bit is what you need than you'd be looking at the Dell Ultrasharp UP3214Q anyway. http://www.tomshardware.com/reviews/ultrasharp-32-up3214q-review,3744-7.html

    Tom's should review Samsung's cheap 4k monitor instead of stuff like this.

    I love the super indepth articles you guys do, but it would be nice if you also did more reviews about less expensive things, like cases. I mean, it's interesting to read about a $1k monitor but it would be more helpful to more people if you did a case roundup or a higher volume of reviews about them. You don't have to stop making monitor reviews or anything because it's certainly not hurting anyone, but it seems like there are more articles about expensive monitors that most people can't buy/don't have a use for in lieu of articles about more fundamental pieces of computer hardware.
    Just my two cents

    $1300 for a simple panel is a joke, specially when "From our experience so far, these 4K monitors work well, but still have some maturing to do." Thank you for the straightforward, no nonsense review. I'll wait.

    Ahh, 24" 4k monitors are a reality now. Antialiasing in games is soon to be a thing of the past. Which is relieving, because that makes the task on graphics cards a lot more manageable.

    It actually makes it worse if not does nothing. 4K is the equivalent, almost, of 1080p using SSAAx4. MSAA is a lot cheaper and most games are resorting to FXAA or MLAA because it's incredibly cheap, works with any rendering method (Deferred rendering doesn't play nice with MSAA), and the quality is almost as good.

    And modern graphics cards can handle that kind of workload. So, since they're basically equivalent, it isn't a lot more to ask of cards to do 4k without any AA.

    To S3amister: First of all I didn't miss the point of this article. I get monitor resolutions. The point is that 4k is the next gimmick made up by the big TV and monitor manufacturers as the "next big thing" to try to get suckers like you to buy into resolutions that the human eye can't even distinguish. You're going to tell me that you can tell a difference between WQHD and 4K? Nonsense. Maybe if you have a 60" screen but with a 24" screen? No way. Get real pal.

    I lust for a 4k monitor in 24 inch, but it must be a 16:10. I currently use the Dell U2412M in vertical mode for word processing, searching eBay, a LOT of searching eBay, etc. I love its 16:10. I previously had a 16:9 and used it in vertical viewing, but it was too narrow. The first 4k 24 inch in 16:10, which pivots to vertical, I will buy in a heartbeat.

    Why limit yourself to that poor mans 2560 x 1600 res? After using a 30 inch for over 3 years im ready to jump to 4K and quarter of an inch sized icons on my display..More real estate.

    It probably will look like Iphones "Retina" display, I just like clear and crisp image on the monitors :)

    I don't know what all the moaning is about reviewing a monitor that is $1K plus. For those that want cheaper monitors reviewed did you ever stop to think that a review like this will persuade people with the funds to buy one which in turn will make them cheaper. I for one would love to own a 4k monitor however I wont pay 1K for one so keep the reviews coming so we can get mass production up on these over the next year or two.

    I understand that the whole point of this review is for 4k monitors. But since it was equally pointed out in the beginning of the review that this is squarely aimed at photographers and other imaging professionals, why not do a shootout with these Dells against some non 4k competition from NEC or Eizo for that matter. Now there is a review I would love to see.
