Dell UP2715K 27-inch 5K Monitor Review

OSD Setup And Calibration

The UP2715K has an efficient menu system but there are many picture presets and options to explore. Pressing one of the side keys brings it up.

OSD Tour

First up is Brightness and Contrast. If you use one of the Cal modes, this menu is disabled in favor of the programmed-in luminance levels. We'll explain that in more detail below.

The dual-DP inputs are the only way to run at 5K. MiniDP is limited to Ultra HD. Both options run at 60Hz.

Input Color Format allows RGB for computer signals and YPbPr for component content, which is most-often seen from media servers and Blu-ray players.

Gamma can be set to either PC (2.2) or Mac (1.8). It should be noted that newer model Apple computers use a 2.2 gamma curve.

There are eight image modes in total. The top five are task specific and allow only brightness and contrast adjustments. Color Temp is the default and includes a white point slider that moves in degrees Kelvin. Its stops are too coarse for precise accuracy but at the 6500K setting it offers reasonably good grayscale tracking.

In the Custom Color mode you can calibrate both gains and offsets for the white point.

Also included is a six-point color management system with saturation and hue controls. In our tests we found the saturation sliders had more impact on color luminance and didn't change the CIE chart points. Hue is useful for tweaking the magenta, cyan and yellow secondaries.

In Color Space mode you can choose locked Adobe RGB and sRGB presets or one of two calibration memories. They are programmed using the included software and an appropriate instrument. We used an i1Pro to create Adobe and sRGB presets of our own that were more accurate than the factory-provided ones.

In the Display menu there are four aspect ratio choices: 16:9, Auto Resize, 4:3 and 1:1 where each pixel is mapped. Lower resolution signals are therefore shown windowed. Response Time, AKA overdrive, can be fast or normal. Even on the fast setting we saw no ghosting whatsoever. It's one of the better examples we've seen and it has a positive effect on panel response and motion blur.

The only audio option is volume. There is no headphone jack or analog input. Signals come by way of DisplayPort.

You can tweak the energy usage settings here. Having the power LED on is almost a waste because it's hidden around the panel's side. Monitor Sleep will turn the UP2715K off when no signal is detected.

The OSD is available in eight languages. You can also adjust its transparency, timeout (up to 60 seconds) and lock it to prevent changes.

Two of the bezel keys are programmable. They can be used to directly access picture modes, brightness/contrast, input source, aspect ratio and volume controls.

The Others menu has the remainder of the system options. Auto Rotate allows the OSD to change its orientation but not the image. For that you'll have to visit the video driver setup. If you wish to return the UP2715K to its factory defaults, that function is here as well.

There's no separate info screen but the OSD always shows the current input and signal numbers at the bottom left. You can also monitor energy consumption in the upper right.

Calibration

Calibration options are many and complex so we'll break this down for you. If you just want to plug and play, we recommend going to Color Space mode and choosing either the sRGB or Adobe RGB preset. They are factory-tuned and will deliver a decent image. Our tests found them to be of adequate accuracy. In Custom mode, you can tweak to your heart's desire with two-point grayscale and six-axis color controls. We achieved a solid result using that method. To unlock the UP2715K's full potential, you'll need to install Dell's calibration software, which is included. It supports X-Rite products like the i1Pro and i1DisplayPro. The monitor must be connected to your PC via USB for this to work. After setting parameters for color gamut and luminance, you simply hang the meter on the screen and wait about 30 minutes for the routine to do its thing. You can see the results of all our experiments in the benchmark tests.

We've provided our recommended settings for Custom mode below.

    On the specifications chart, it says that the panel is AMVA, but a little below the chart, it's mentioned that it's an IPS panel instead. Going by the conclusion and contrast ratio, definitely IPS. Also, 3 year warranty, that's.... so little for something that clearly deserves a 5 year or more, in my opinion.

    It is indeed AH-IPS not AMVA. Thanks for pointing out our error.

    Oh look its a retina display with retina pricetag
  • Jeff_53
    Why isn't the MSRP on the first or last page? My interest in the product and features is directly tied to it's price.
  • apertotes
    That contrast... ugh! For 99% of users, contrast is much more important than color fidelity.

    How about a test of the DELL S2716DG? Especiall vs the ASUS ROG PG279Q.

    Never mind. That would be TN vs IPS. You could compare it to the PG278Q though.

    + for the price thing. It is absolutely irritating. Hope you guys fix this.
  • PellehDin
    If they fix the price issue - and the current price is about $1,500 and up - you might just skip the article, which they don't want.
  • CBender
    I don't read the review articles just because of that. I am going to read a full review for a product not that I can't afford, but a product that I consider it be way overpriced (not for this particular review)

    I know I'm a gamer who's out of place in a professional work monitor article, but between the low response time, and you statement that you could play at 40fps, id love to see an article about gaming at 5k, particularly with titan x vs 980 ti benches
  • cats_Paw
    Well, I guess we needed higher resolution to keep "can it run crysis" alive.
  • It is cool to see they are pushing 5k and what not but it is absulutely useless for PC on 27". The only perfect resolution right now is 2K 144Hz, everything over that is waste.

    I have a Dell U3415W, a 34 inch Ultrawide. Price on it was also $1.5K and it did not move, but during the holiday season it fell to $700.

    So if you are interested in a product don't just give up because you can't afford it, it can easily fall into your price range as long as you have reasonable expectations.

    I had a 24 inch monitor and switched to a 32 inch TV and later to a 34 inch monitor.

    I have to say, you can never go back in size ever again. I would not even look at 27 inch.

    Maybe if you've got poor eyesight, just want to game or have a sub 25" panel.
    I switched from 1440 to 5k ~18 months ago (both 27"), and the difference is amazing.
    Remember this is a pro grade screen for pro users. What matters to them is colour range and accuracy. Refresh rate means almost nothing.

    At $1500 I would just buy a refurbished iMac. I know this monitor will outlast the hardware within the iMac. Others may want to run a machine that is more capable than an iMac, but it's interesting to me how an AIO can sometimes be the same price or cheaper than just the monitor. The 5k iMac maxes out at 4k running Windows the last time I checked though.

    Something's amiss. How is it possible to achieve 100 percent Adobe RGB while just using W-LED backlighting?
  • zodiacfml
    Never mind. The capability seems pretty standard on 5K displays.
