Product information

Description

The Dell UltraSharp UP2720Q is a 27" 4K (3840 x 2160) IPS LCD monitor with a matte screen surface, designed for accurate color work and versatile connectivity. It features an integrated colorimeter, Thunderbolt™ 3 support, a built-in USB hub and a height-adjustable stand with VESA mounting compatibility. The display offers wide 178°/178° viewing angles and a typical brightness of 250 cd/m².

Advantages

The UP2720Q combines a native 4K IPS panel with an integrated colorimeter for on-demand color calibration, helping maintain color consistency without additional external tools. Thunderbolt 3 provides fast data and power delivery alongside video transmission, while the built-in USB hub simplifies peripheral connections. The matte surface reduces reflections for more comfortable long sessions and the adjustable stand with VESA support allows flexible positioning.

Suitable for

  • Professional photo and video editing where color accuracy is important
  • Graphic design and print prepress workflows requiring consistent color calibration
  • Office and multitasking setups that benefit from 4K resolution and Thunderbolt 3 connectivity
  • Users who prefer a matte screen to reduce glare

When it may not be suitable

This monitor may be unnecessary for casual users or general home entertainment if 4K color-critical features are not required. Gamers seeking very low response times or high refresh rates may prefer displays with faster response specs and higher refresh rates than the UP2720Q's 8 ms and 60 Hz.

Key specifications

  • Screen size: 27 in (68.6 cm)
  • Resolution: 3840 x 2160 (4K Ultra HD)
  • Panel type: IPS LCD
  • Surface: Matte
  • Pixel pitch: 0.155 x 0.155 mm
  • Response time: 8 ms
  • Contrast ratio (typical): 1300:1
  • Brightness (typical): 250 cd/m²
  • Viewing angles: 178° horizontal / 178° vertical
  • Connectivity: Thunderbolt 3, DisplayPort, HDMI, USB Type-C downstream port (1), built-in USB hub
  • Speakers: None (no built-in speakers)
  • Ergonomics: Height adjustment, VESA mount compatible
  • Color: Black

How to use

Connect the monitor to your computer using Thunderbolt 3, DisplayPort or HDMI depending on your host device and required bandwidth. Use the integrated colorimeter to perform on-screen calibration following Dell's calibration software instructions to achieve accurate color profiles. Adjust height and tilt for ergonomic viewing and connect peripherals to the built-in USB hub. For optimal results in color-critical work, allow the monitor to warm up and perform periodic recalibration.

What to consider before purchase

  • Whether you need an integrated colorimeter or already use external calibration tools
  • Your system's compatibility with Thunderbolt 3 and support for 4K at 60 Hz
  • Requirement for built-in speakers (this model has none)
  • Desk space and whether you will use the included stand or a VESA mount

Usage recommendations

For accurate color work, connect via Thunderbolt 3 or DisplayPort, run Dell's calibration routine on first setup and recalibrate regularly. Keep ambient lighting consistent and use the matte surface to reduce reflections during editing sessions.
