Dell S2719DM: a stylish 27-inch Quad HD monitor

Presentation

The Dell S2719DM has a 27-inch IPS panel with a Quad HD definition of 2,560 x 1,440 px. It supports a conventional refresh rate, limited to 60 Hz, compatible with FreeSync over a slightly wider range (48 to 75 Hz). The ergonomics and the connections are in the image of its design, very refined, even too much.

This screen is quite expensive for a 27 inch QHD. It is sold for around 400 € while there are very good models like the Iiyama ProLite B2783QSU for around 280 €. This is the price to put for a very beautiful design and beautiful finishes.

Ergonomics

The Dell S2719DM has a sleek design with a very rigid one-piece aluminum stand. The finishes are impeccable and the different elements are well adjusted.

Like the front, the design of the rear is extremely refined. Dell has placed the connectors in the axis of the foot to maintain a minimalist look of the most beautiful effect. The passage of cables is limited to a hole in the foot. We would have preferred a slightly more complete system to completely hide the cables, as on the BenQ GW2480.

This system is certainly elegant, but it has a major flaw: it prevents the height adjustment of the monitor as well as rotation. You just have to settle for the only tilt adjustment between -5 ° and + 20 °. However, the base of a block seems quite sturdy.

Connectivity is limited to two HDMI inputs and a headphone output. There is no DisplayPort input and Dell also skips the USB hub. Finally, the screen does not carry speakers. So you have to go through a PC speaker kit.

The extreme thinness of the product forced Dell to place the power outside, one less for the integration, but one more for the repair in case of failure of the block. The size of this food remains contained.

The five buttons on the front panel allow you to turn on the screen and access the settings. This system is not the most practical and handling errors are frequent. Fortunately, the menus are clear and the proposed settings are numerous (brightness, contrast, blue light filter, overdrive ...).

On a standard desk (140 x 60 cm), the Dell S2719DM takes up very little space thanks to a very compact stand whose depth does not exceed 16 cm.

We have measured consumption at around 24 watts with a white set at 150 cd / m². Relative consumption thus reaches 119 W / m². This is much more than the average of the last screens tested (100 W / m²) and this monitor is not really an example on this point.

Colors and contrast

Default: average gray temperature: 6.030 K

Default: gamma curve at 2.3

Default: Average Delta E at 2.8

By default, the Dell S2718D displays a fairly well calibrated image. The temperature curve is fairly stable, but the average measured at 6,030 K is a little far from the 6,500 K reference. This results in a slightly too hot rendering. The gamma curve lacks stability. Its average is 2.3, fairly close to the reference 2.2, but the light gray is slightly clogged. Finally, the average Delta E is good (2.8), but the green, red and blue are above 4. Remember that the eye perceives the difference in colors when the Delta E is greater than 3.

Manual adjustment: average gray temperature: 6.030 K

Manual adjustment: gamma curve at 2.3

Manual setting: Average Delta E at 2.8

By lowering the brightness to 23, we obtain a white at 150 cd / m² on our test pattern. The decrease in brightness does not change the behavior of the screen, which always offers the same rendering. The screen offers many other display modes, but none offers better rendering by default than the standard mode used here.

Calibrated: average gray temperature: 6,580 K

Calibrated: gamma curve at 2.2

Calibrated: Average Delta E at 2.1

As often, calibration with the probe stabilizes the gamma and temperature curves. The latter dates back to an average of 6,580 K, much closer to the reference 6,500 K. The gamma is perfectly stable on the reference value (2.2). Finally, the average delta E goes to 2.1, but the red, green and blue remain above 3.

Measured at 1040: 1, the contrast ratio of this IPS panel is average. Most IPS monitors exceed the rate of 1000: 1 and some models, notably in PLS (Philips 276E7), sometimes do better (1300: 1). As with all IPS monitors, blacks lack depth. This has no impact when used in daylight, but in the dark, blacks appear gray. For better contrast, you should turn to monitors using a VA panel, such as the AOC Q3279VWF, whose contrast exceeds a ratio of 3000: 1.

We measured the average difference in brightness uniformity at only 11% over the entire 27-inch panel; very good value. We did not see any clouding phenomenon on the model we tested. Finally, as always with IPS panels, the viewing angles are exemplary and there is very little variation in brightness when you are positioned at 45 ° from the display axis.

Reactivity

The Dell S2719DM does not use Pulse Width Modulation (PWM) to adjust the brightness. There is therefore no flickering when the brightness is reduced and this does not cause headaches for the most sensitive people. It also offers a blue light reduction mode called ComfortView.

The Dell S2719DM is compatible with FreeSync technology which dynamically shifts the screen refresh rate to the number of images per second produced by the graphics card, in order to avoid the phenomenon of image tearing (tearing) and micro-slowdowns (stuttering). The supported frequency range is low since the FreeSync only works between 48 and 75 Hz, but it still allows to smooth the game in native definition Quad HD with a mid-range graphics card, typically when the graphics card drops below the 60 frames per second .

We measured the remanence time at 10 ms with the default overdrive setting ("Normal"). This setting reduces the ghosting effect without causing reverse ghosting, unlike what happens with an even more advanced setting ("Faster" mode). We measured the delay in display (input lag) at 10.5 ms, an excellent value. There is thus no lag between the action performed on the keyboard or the mouse and its repercussion on the screen.

Conclusion

The Dell S2719DM is a very beautiful monitor with a sleek and minimalist design that will delight fans of sobriety. Too bad Dell did not push the concept to the end by allowing to completely hide the cables. It is suitable for office use with its Quad HD definition and open viewing angles, but it is not recommended for gaming because of its high persistence or for video because of its limited contrast.
