Two-minute review

The Dell S2721D, along with the rest of the Dell S series monitors, is all about bringing a quality experience without breaking the bank.  At its $319 (£279, AU$429) price point, the entry-level Dell S2721D offers a reasonable package. The 27-inch 1440p screen has a 75Hz refresh-rate which should satisfy any casual gamer. Meanwhile, users more interested in a monitor for video or photo editing will be satisfied with the vivid IPS panel that hits 99% of the sRGB color gamut.

Just be mindful of some caveats – built-in speakers provide limited audio clarity and they don’t get very loud. For a QHD monitor in 2020, not supporting high dynamic range (HDR) is also disappointing, but not terribly surprising in such an affordable display. Anyone willing to overlook those flaws may get a lot of mileage out of the S2721D.

The monitor itself isn’t bulky by design thanks to its three-sided ultrathin bezel design. Two HDMI 1.4 ports, DisplayPort 1.2, audio line-out, power connector and security lock slot sit underneath the rear. Having some sort of USB connectivity would have gone a long way in terms of versatility. Setting up the stand is fairly easy while positing the monitor along the X, Y and Z axes feels smooth. The ability to turn the S2721D vertically is a plus as well. Be mindful that plugging cables while the stand is attached is slightly difficult. Monitor controls for things like power, settings and volume are located on the bottom right. 

3w speakers placed at the bottom seem like more of an afterthought addition than something fully featured. Volume levels sound somewhat low even at its highest setting. However, in a totally silent room, sound quality is reasonable. Users will probably be better off using headphones or buying speakers.

The Dell S2721D also has a lot to offer to casual PC gamers. Besides the 75Hz refresh rate, it supports AMD FreeSync. Playing shooters like Call of Duty: Modern Warfare or Doom Eternal look rich and vibrant with colors. Having the high refresh-rate can even potentially provide a slight competitive advantage. There are some pre-set color settings for various gaming genres from first-person-shooters to RTS and even watching movies. 

Editing photos and videos is also a treat on the S2721D, due to the 99 percent sRGB color coverage. Regardless of how the S2721D is positioned, the monitor features anti-glare with 3H hardness, so you don’t have to worry about it getting scratched easily. Whether gaming, editing media or general use, the 27-inch screen is beautiful. Multi-taskers can also utilize Dell’s Display Manager to arrange various screen layouts too. 

The S2721D accomplishes a lot through its approachable price. Individuals looking for a quality 27-inch QHD monitor that’ll relatively fit into any office space are in for a treat. Gaming and media editing performance is a bit more than adequate. Just don’t expect much beyond that. Sub-par speakers, lack of HDR and lack of USB connections keeps the S2721D makes this more of a no-frills package.

Matrix color depth An important parameter for those who work with color, for example, process photos. The most widely used monitors with 8-bit matrices. Displays with greater color depth and bit depth are significantly more expensive. 8 bit
FRC (Frame rate control) Technology that increases the color depth of the matrix. During operation, quickly switches pixels between color shades, due to which the user sees an intermediate shade. Please note that some people are vulnerable to such flickering, their eyes get tired quickly, there is a feeling of dryness. However, most people do not feel any discomfort, and the vast majority of monitors come with FRC. N/A

Backlight Modern sensors don’t emit light, so they need a backlight. The type of backlight affects the image quality, the correct display of colors, eye fatigue. In addition, over time, the backlight may degrade, distorting the color reproduction. W-LED

Eye-safe monitors without PWM

Manufacturers who care about your eyesight do not use PWM (pulse-width modulation) backlight brightness control, the principle of which is to turn on and turning off the backlight LEDs at a high frequency, resulting in eye fatigue. Please note that many monitor models provide adequate brightness control only up to some limit, below which PWM comes into play. Look for a review in which the absence of PWM at any brightness is confirmed by measurements.

Brightness Maximum display brightness. All modern monitors produce sufficient maximum brightness. When buying, it is worth checking the minimum so that your eyes are comfortable in low light. 350 cd/m2
Static contrast A value that determines how much contrast the monitor can produce simultaneously on a single frame. 1000:1
Dynamic Contrast Mostly marketing and advertising. This indicates the difference between the maximum possible bright and dark color on the display, which is almost impossible in real use. Pay attention to static contrast. N/A
Viewing angles (horizontal/vertical) Viewing angles at which the manufacturer believes the image will remain within acceptable quality limits. Be prepared for noticeable color distortion. 178 / 178 °


Maximum vertical refresh rate An important value for gamers. Shows how many times per second the image on the matrix is ​​updated. The higher the refresh rate, the smoother and more comfortable the game. The simplest monitors give out 60 Hz, budget gaming 120 Hz, the top-end ones – 240, 360 and even higher. An intermediate version of 144 Hz is gaining more and more popularity. It is important to choose a video card that consistently produces a number of frames equal to the monitor frequency, otherwise you will not feel any improvement. 75Hz
Minimum Vertical Refresh Rate 48Hz
Maximum Horizontal Frequency The maximum horizontal scan rate, indicating the number of horizontal lines drawn by the screen per second. 115 ms
Minimum Horizontal Scan Rate The minimum horizontal scan rate, indicating the number of horizontal lines drawn by the screen per second. 30ms
Minimum Response Time GtG (Grey to Gray) High response time sensors will delight you with loops in action-packed movie scenes with games. GtG – the time during which the matrix switches the brightness on gray from minimum to almost maximum. Considering that all colors are displayed in games, it poorly reflects the real performance, but it is stubbornly indicated by manufacturers in promotional materials. Modern monitors have overclocking technologies in which the response time is reduced, but image artifacts appear. Overclocking functions vary among manufacturers, some really help, some do nothing but damage the picture. 4 ms
Medium response time BWB (Black-White-Black), BtB (Black to Back) High response time sensors will delight you with loops in fast-paced scenes of movies with games. Average response time – the time during which the matrix switches from black to white and back. Modern monitors have overclocking technologies in which the response time is reduced, but image artifacts appear. Overclocking functions vary among manufacturers, some really help, some do nothing but damage the picture. 8ms
Input lag Another important parameter for gamers. The delay between the signal from the computer to the monitor and the display of the picture on the screen. At high values, you will experience a delay between your actions and the display on the screen. n/a
