The Desview D21 Pro is a 21.5" 1000-nit broadcast monitor designed for vertical and horizontal production. The picture splits into up to four independently adjustable windows, SDI and HDMI are monitored with full waveform, HDR and 3D-LUT, and anamorphic de-squeeze, cropping and 9:16 markers help too. The pressure-resistant housing with a sliding cover opens in 3 seconds.
The Desview D21 Pro vertical display broadcast monitor represents a new generation of professional monitoring solutions, purpose-built for today’s vertical content era while remaining fully compatible with traditional horizontal workflows. Equipped with a 21.5" 10-bit IPS display, the D21 Pro delivers accurate colour reproduction with 99.5% DCI-P3 coverage, a 1000:1 contrast ratio and 1000-nit brightness, ensuring excellent visibility both indoors and outdoors.

The screen can be set to dual, triple or quad view and supports picture-in-picture mode to meet different monitoring needs (Main menu → Input settings → Multi-window). This flexibility makes the D21 Pro ideal for multi-camera productions and complex monitoring setups.

Designed for efficiency on set, the D21 Pro features an innovative 3-second quick-release sliding cover, allowing rapid deployment straight out of the case and a quick response to shooting needs.
Military-grade anti-collision corner guards are tested for a 1.5-metre vertical drop.

External 1/4" and 3/8" (ARRI) screw points and VESA mount compatibility allow seamless integration with light stands, carts and studio rigs – wireless video transmission, lighting and other accessories can be installed in seconds.
The housing uses a multi-layer composite pressure-resistant material that withstands up to 80 kg of load, so complex environments on set are no concern.
The VESA mount supports quick installation on a light stand and provides fast, stable monitoring for film shooting, live broadcast and multi-camera transitions.

When multiple windows are used, the brightness, contrast, colour temperature, hue, saturation, sharpness, distortion and flip of each window can be adjusted separately.

Anamorphic de-squeeze for 1.33×, 1.6×, 2.0×, 2.35× and other mainstream ratios reveals the wide-screen picture in real time on set – no more time-consuming guesswork in post-production.

The combination of hardware rotation, multi-display split screen and professional monitoring tools achieves seamless switching between horizontal and vertical shooting – core technical support for film shooting, especially short films and creator content.

9:16 composition markers can be set in a single window to facilitate post-production. Anamorphic de-squeeze, horizontal and vertical cropping and 9:16 markers make the D21 Pro especially powerful for film, advertising and social media production.

When using SDI input, you can select the channel to be played back.

The camera position reminder helps the crew manage the shoot and greatly improves shooting efficiency.

Professional connectivity includes three 3G-SDI inputs with loop outputs for stable transmission and multi-device collaboration, and two HDMI 2.0 inputs with one output supporting up to 4K 60p, transmitted losslessly, smoother and clearer. Military-grade edge protection around the SDI and HDMI connectors effectively prevents interface damage.

The monitor supports full waveform monitoring for both SDI and HDMI signals, and frame-level data visualisation brings confidence to exposure and colour control.

Built-in LUTs in various styles and support for importing custom LUTs let you define your own film look directly in the monitor.

The 21.5" professional 10-bit IPS panel supports 33 × 33 × 33 hardware 3D-LUT, achieves real-time and accurate colour calibration and restores true colours to the greatest extent.

Using the science of light and shadow to end guesswork on set: when the brightness of the highlights and the depth of the shadows are both quantified, every frame withstands magnification and the image truly comes to life.

AC power, XLR DC input or V-mount battery support make the monitor suitable for studio, outdoor and mobile shooting.

The front tally light provides three colour signals – red, green and blue – further enhancing the monitor’s suitability for live production and broadcast.

Built-in histograms, waveform and vectorscope intuitively display light, shade and colour conditions, allowing you to observe every frame and achieve the best results. False colour, zebra lines, peak focus, monochrome display, colour settings, aspect ratio, centre marker, safety frame, composition assist, shortcut keys, multi-view display and picture-in-picture settings are also available.

The Desview D21 Pro is a top-of-the-line 21.5" broadcast monitor with a high brightness of 1000 nits and support for 3G-SDI/HDMI, making it ideal for studio production and live broadcasting. To maximize its use in a professional environment, it is recommended to pair it with wireless transmission systems for flexible monitoring and teleprompters for presenters.
Wireless Transmission and Audio - Accessories for wireless signal reception to the monitor and professional audio recording.
Teleprompters - Teleprompters compatible with professional production setups to facilitate work in front of the camera.
