Dell S2721QS 27 Inch 4K UHD Review

Image Quality


The display is based upon a 27 ″ IPS (in-plane switching) panel which provides consistent colors and also large 178 ° viewing angles, making sure flawless image quality no matter the angle you’re checking out the display.

It supports 10-bit color depth via dithering offering 1.07 billion colors as well as covers the conventional 99% sRGB color space for exact shade recreation.

Simply how specific as well as consistent the colors are will differ throughout different units of the display, yet it will do simply great for entry-level color-critical work.

More major and also specialist designers, editors, and also photographers need to opt for a little bit a lot more expensive 4K IPS model with a guaranteed factory-calibration at Delta E below 2 or 3, such as the Dell U2720Q from Dell’s UltraSharp series.

Naturally, if you have a colorimeter, you can obtain exceptional shade precision out of the Dell S2721QS, too.

Going on, the Dell S2721QS has a solid optimal illumination of 350-nits and a fixed comparison proportion of 1,300:1, which is outstanding for a 4K IPS keep track of at this rate range.

It will be more than brilliant sufficient under regular illumination conditions.

While the comparison proportion will not give you with as deep blacks as that of VA (Vertical Positioning) panels with a ~ 3,000:1 contrast ratio, the photo top quality is total exceptional with decent detail quality in the darkness of the picture.

Besides, VA panels have their own downsides, such as gamma shifts, that make them inadequate for color-critical job.

4K resolution leads to a high pixel-per-inch proportion of 163 PPI on the 27 ″ sized screen of the Dell S2721QS monitor.

This indicates that you obtain plenty of display real estate as well as vivid information and also sharp message, but you will require to make use of scaling in order to make small letters legible.

Finally, note that the Dell S2721QS supports HDR (High Dynamic Range), however given that it does not have proper display screen abilities, including wide shade gamut, HDR material will certainly look washed out.

Some content could look somewhat much better, but you’ll mainly like it disabled.


While not marketed as a gaming monitor, the Dell S2721QS provides an instead good gaming experience, provided that you have a sufficient PC system to run video games at 4K as it’s quite requiring.

Input lag totals up to only ~ 9ms, that makes for imperceptible hold-up at 60Hz.

Next, there are 3 feedback time overdrive settings: Regular, Fast, as well as Extreme.

We recommend using either the Typical or Quick setting as ‘Extreme’ presses the pixels to transform as well fast therefore creating inverse ghosting (i.e. pixel overshoot).

There’s no noticeable trailing behind fast-moving things, but also for fluid gameplay, we very suggest a greater refresh price video gaming display.

In case you mainly play much more graphically-oriented video games as well as like better graphics with 60 FPS to greater FPS at a reduced resolution, the Dell S2721QS will certainly do just fine.

It also supports AMD FreeSync with a 40-60Hz VRR (variable refresh rate) variety. So, if you have a suitable graphics card, you can allow FreeSync as well as there’ll be no display tearing or stammering as long as your FPS (Frames Per Second) is between 40 and 60.
Even more, while the display is not certified as G-SYNC Compatible by NVIDIA, FreeSync works with compatible NVIDIA GeForce cards with no issues. However, your mileage may differ right here, depending on your certain system.

Bear in mind that all IPS keeps an eye on deal with IPS glow, which can be called visible ‘radiant’ around the bend of the display that alters in strength relying on the angle you’re considering the screen.
The quantity of IPS radiance differs throughout different units of screens, just like backlight bleeding, however in many cases, it’s completely convenient.

Lastly, note that the Dell S2721QS display screen utilizes a flicker-free backlight and that it has an integrated low-blue light filter (the ComfortView picture predetermined).


The OSD (On-Screen Present) menu of the display is well-organized. To browse it, you make use of four hotkeys put at the right side of the screen. Two of those hotkeys can be assigned to faster ways of your option under the ‘Personalize’ section.

Aside from the Requirement and also ComfortView image presets, you’ll discover FPS, RTS, RPG, Motion Picture, Cozy, Great, as well as Customized Shade (user configurable red, eco-friendly, and blue shade levels) settings.

Various other picture changes tools include brightness, contrast, sharpness, and also hue/saturation, however there are no gamma presets readily available.

For pc gaming, there’s the Dark Stabilizer function, which boosts exposure of items in the dark.

Photo in Photo and Image by Picture are supported also.

Additionally, the display has a low-haze (25%) matte anti-glare covering, which gets rid of representations, yet protects the picture top quality as it does not make it grainy.

Connectivity alternatives consist of 2 HDMI 2.0 ports, DisplayPort 1.2, an audio line-out port, and also dual 3W integrated audio speakers.
