Dell S2719DGF 155Hz Gaming Monitor Review: Speedy QHD

Viewing Angles, Uniformity, Response and Lag

Viewing Angles

Looking at the flaws in the S2719DGF’s off-axis photo, you can tell that it’s a TN panel. But if you compare it to other TN displays, it fares quite well. There is a green shift and a 40 percent reduction in brightness to the sides, but all the dark steps can be seen clearly. If you view this monitor from 45 degrees, you’ll still see a decent picture. Even the top view is better than other TN screens we’ve photographed. While the image was still largely washed out, we could still see all the brightness steps from light to dark. You won’t have to give up much off-center viewing quality to reap the benefits of the S2719DGF’s extra speed.

Screen Uniformity

To learn how we measure screen uniformity, click here.

Our sample had a few just-visible hotspots in its corners. We could see them in our black field pattern, but at any higher brightness they disappeared. During our gaming sessions, we didn’t experience any issues that detracted from gameplay. While this is a bit below average among our typical review subjects, it is by no means a deal-breaker.

Pixel Response & Input Lag

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

In monitors, it seems that once speed goes over a 144Hz refresh rate, the differences in screen response are small to non-existent. You can see in the graphs above that the PG27V’s 165Hz isn’t enough to beat the S2719DGF in our top-to-bottom full-transition test. When checking input lag, our top three screens were within a hair’s breadth of each other. We doubt even the most skilled players are able to detect a 4ms difference.

These charts make a clear case in favor of faster monitors that operate at 144Hz and above. With faster draw times comes lower motion blur. Then, you won’t have to rely on backlight strobes or excessive overdrive to smooth out the action. And input lag is always lower at higher refresh rates. That’s a benefit, even for casual gamers.

    poor contrast, poor gamut, poor viewing angles, simulated bit depth through dithering?Yep it's TN
  • thealmightyeyeball
    I bought one of these and returned it. It had a nice picture for TN, but I was getting horrible tears playing DooM using freesync. My old reliable monitor does not do this.

    Will an 11hz refresh rate overclock do much more than let them put 155hz on the box?
  • richardvday
    Yea 11hz is nothing to get excited about.
    Seems high for a tn monitor. Meh
  • AlistairAB
    They get a deservedly bad rap. Gamma will be all way off. Look at the file explorer icon for example, it will bloom on TN monitors. Painful to look at unless you are very young. It's garbage, and they should stop making TN monitors. "Rap" comes from experience.

    Why is the screen size in your table listed as 24.5 inches? It's a 27 inch...
  • milkod2001
    make it 4k at 32" size, 120Hz would do. Is that so much to ask in nearly 2019?
    1440p monitors are so 2010. Still have one, there is no way i'lll get another only because it has faster refresh rate.

    Am i missing something here?? This is a FREESYNC monitor for goodness sakes. Which means, Tom's was supposed to test it with an AMD card, then report to us how well Freesync worked in games. Come on guys, pull up your socks....
  • jaexyr
    TN right at the beginning, that's all I needed to see
  • Giroro
    I mean ... at least it's not curved.

    He did test it with an R9 285. He probably should have used a more recent GPU but oh well I guess.

    Depends on what you want. Unless you have a top-end GPU, 1440p still makes a lot of sense.

    I do agree with you on one thing: 4k monitor @ 32". That's what I'd want, if I went 4k.

    24.5 inches???? Isn't this 27"?

    Please Asus, just give us what we really want...

    How is the response time, input lag, and the ghosting/color banding compared to the S2716DG?

    Just bought one of these over black Friday which replaced an older 1080 VA panel. The whole time I was thinking I was more of an "IPS" guy and would hate this TN panel. But then I remember the reason I went VA a couple years ago -- it was because of the light bleed around the edges which is typical for IPS. VA doesn't usually have that problem and the contrast is better. However, after putting this new TN panel next to the VA -- it just makes the VA look like crap. The higher tier TN panels of today are excellent and the S2719DGF is the best monitor I've ever had, period! The colors are rich and accurate, it has good contrast, good viewing angle. It's just a great overall monitor. So good I decided to buy a second one and retire my VA panel completely.
