Dell UP2715K 27-inch 5K Monitor Review

Viewing Angles, Uniformity, Response And Lag

To learn how we measure screen uniformity, please click here.

From the sides, the UP2715K looks like most IPS screens except it has a little less light falloff. That's likely due to the tight gap between the anti-glare and TFT layers. Bringing the light valves and grid polarizer forward means less image degradation as you move off-axis. From the top, dimming is greater and whites take on a green cast. While not the equal of IPS-ADS or AHVA, this AH-IPS panel does quite well.

Screen Uniformity: Luminance

Our sample showed visible light bleed in the upper left and lower right corners. Aside from those two zones, the rest of the screen looks fine. Those areas spoiled what could have been a good result. Without them, uniformity would have measured closer to our 10-percent preferred level.

Here's the white field measurement.

There are no visible problems in the white field test. Even the center zone, which is usually a little hotter, looks identical to the surrounding areas. Even though the Dell finishes second-to-last, it looks the same as the higher-finishing screens.

Screen Uniformity: Color

We saw no shifts in the color uniformity test. According to our meter, the lower left zone has a little extra green but we couldn't see it with the naked eye. Dell doesn't offer a uniformity compensation feature on the UP2715K and given these results, we can see it's not needed. The light bleed seen in the black field test may not appear on other examples.

Pixel Response And Input Lag

Please click here to read up on our pixel response and input lag testing procedures.

Fast panel response is a good thing on any monitor and isn't only an asset in games. Motion blur is inherent in any LCD design so when it comes to moving content, the faster response the better. On the Response setting's Fast option we saw no ghosting in the BlurBusters UFO test and measured an excellent 19ms draw time for the black-to-white test. The Dell's motion resolution is about as good as it gets for a 60Hz display.

Here are the lag results.

While we don't expect many gamers to shop the UP2715K, those that do will enjoy relatively low input lag. Of course you'll need an expensive video card to achieve any sort of playable frame rate at 5K but our Titan X is up to the task. Without adaptive refresh there is some visible tearing but by turning detail levels down a bit, we could maintain a playable 40fps in most first-person shooters.

    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.

    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?

    Never mind. The capability seems pretty standard on 5K displays.
