Buying the Dell Plus S2725QS 27-inch 4K monitor: what should you really look for?

The Dell Plus S2725QS 27-inch 4K monitor might seem like an easy choice on paper. Yet many buyers focus mainly on resolution, refresh rate and price. This can mean overlooking important details, such as the right connection for 4K at 120 Hz, how adjustable the stand is and the difference between USB-C and standard HDMI.

For people working from home, students, business users and casual gamers, three pitfalls are particularly worth avoiding:

  • A high refresh rate without a suitable cable or source device. A monitor may support 120 Hz, but your laptop, desktop, cable or games console must also be able to output that signal.
  • Assuming 4K automatically means better ergonomics. A sharp 27-inch monitor is no help if the screen is too low or cannot be tilted properly.
  • Not checking the connections in advance. HDMI, DisplayPort and USB-C have different functions. USB-C, for example, can combine video, data and power, while HDMI and DisplayPort are mainly used for video and audio.

The key specifications explained

1. 3840 x 2160 on a 27-inch screen

The Dell S2725QS has a resolution of 3840 x 2160 pixels, also known as 4K Ultra HD. On a 27-inch screen, that works out at around 163 pixels per inch. This allows text, spreadsheets, photos and fine interface details to be displayed with plenty of detail.

A 4K monitor does demand more from your computer than a Full HD screen. So check that your laptop or desktop supports 3840 x 2160 at your preferred refresh rate. For office work, 4K is particularly useful if you often have several windows open side by side or work with small text.

2. 120 Hz and FreeSync Premium

The S2725QS supports a refresh rate of up to 120 Hz. This means the picture is refreshed more times per second than on a standard 60 Hz monitor. Windows, videos and games in motion can therefore look smoother, depending on the source and settings.

According to the listed product specifications, the monitor supports AMD FreeSync Premium. This technology can match the monitor’s refresh rate to that of a compatible graphics card. The results depend on your hardware, drivers and game settings. NVIDIA G-Sync is not officially certified for this model, so operation through the settings is not guaranteed.

The stated response time is 8 ms GTG, with a fast mode of 5 ms GTG. This is useful information for casual gaming, but it is not the same as a guarantee of competitive gaming performance.

3. Connections and compatibility

According to the product details, the Dell Plus S2725QS has:

  • 1 x DisplayPort 1.4
  • 2 x HDMI 2.1
  • A matte screen with an anti-glare coating
  • 100 x 100 mm VESA mounting

DisplayPort 1.4 is useful for a computer that needs to drive 4K at a high refresh rate. HDMI 2.1 can be handy for compatible consoles or other devices, but always check the output of the source device you’re connecting.

Note the difference between this model and the Dell Plus S2725QC. As well as HDMI, the specifications provided for that model also list USB-C with up to 65 W Power Delivery and USB-A ports. This can be handy if you want to keep cables to a minimum on your desk. If you mainly want to connect a monitor and don’t need a USB-C dock, the S2725QS offers a simpler range of connections.

The IPS panel and ergonomics in everyday use

The Dell S2725QS uses an IPS panel with a viewing angle of 178 degrees horizontally and vertically. IPS is a popular choice for office work and entertainment, as colours and contrast remain fairly consistent when viewed from different positions. The product specifications list a brightness of 350 cd/m², a static contrast ratio of 1,500:1 and a 10-bit colour depth.

The stand is height-adjustable by 130 mm. You can also tilt and swivel the screen, and use it in portrait mode. The pivot function is useful for long web pages, documents and lines of code. If you want to use a monitor arm, the VESA mounting point is important.

When the monitor arrives, check that the stand is firmly attached and place the monitor on a stable, level surface. Keep the ventilation openings clear and don’t apply liquids directly to the screen. According to the product specifications, the included cables are a DisplayPort cable, an HDMI cable and a power cable.
