The Desview D21 is a 21.5" broadcast and director monitor with 400-nit brightness for live production, studios and multi-camera control rooms. The screen splits into up to four views including vertical layouts, and HDMI (4K 60p) and 3G-SDI sources are checked with full waveform and 3D-LUT. It comes in a protective case with a sunshade and runs on mains, an XLR adapter or a V-mount battery.
The Desview D21 broadcast monitor is designed for professional live production, broadcast engineering and multi-camera monitoring environments. Its multi-view display system supports single, dual, triple and quad layouts as well as picture-in-picture mode, so several video sources can be monitored at once with ease. The 400-nit display ensures clear visibility in the studio and the control room.

The screen can be set to single, dual, triple or quad view and supports picture-in-picture mode to meet different monitoring needs.
H in the layout name stands for a horizontal picture and V for a vertical one – layouts with vertical windows suit short vertical videos.

The D21 has built-in full waveform monitoring and supports both HDMI and SDI modes. Waveform diagrams help you better understand and analyse the quality of the video signal.

Multiple LUT styles are built in and custom LUTs can be imported. Define your own creative cinematic style, whatever you like.

To better meet the high standards of film and television production, Desview has completely upgraded the protective case of its D-series director monitors. The well-thought-out design makes work on set more efficient.

The flip-cover quick-access design responds to shooting needs in 3 seconds. A built-in wireless transmission mounting module and accessory storage zones support moves without dismantling, so the setup is ready to use straight out of the box.
D-series monitors in the new protective case easily stand upright for vertical monitoring without the need to buy a support bracket.
The rear VESA interface enables instant mounting on light stands, providing fast and stable monitoring for vertical short dramas, live streams and multi-camera transitions.

Aviation-grade wear-resistant and corrosion-resistant materials withstand high-intensity handling and multi-location transitions, extending the equipment life cycle with lower maintenance costs.
The top of the protective case integrates six 1/4" threads, two 3/8" threads and two cold-shoe interfaces, compatible with multi-device operation and meeting the needs of complex shooting scenarios.
The protective case complies with air-transport standards, assisting seamless cross-region shooting.

High-definition image quality with a physical resolution of 1920 × 1080. Vibrant colours and LED backlight.

A large screen with a professional colour gamut and wide viewing angle – no colour shift when viewed from any angle.
Built-in BT.2020, SMPTE-C, Rec.709 and DCI-P3 colour spaces adapt to different video production workflows.

HDR monitoring support brings more dynamic range, more image detail and more distinct image levels.

Three 4K 60p HDMI signal inputs and one output transmit the picture without loss, making it smoother and clearer.
Two SDI inputs and two SDI loop outputs provide flexibility and diversity for your creations. Easily connect multiple devices and unlock unlimited creative possibilities.

The monitor supports V-mount batteries, an AC power cord and an XLR power adapter. Three different power supply modes adapt to the shooting needs of different scenes.

The front tally light provides three different colour signals: red, green and blue. The T stand shown is optional.

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.

Supporting both 4K HDMI and 3G-SDI inputs, the monitor offers flexible connectivity for modern broadcast workflows. Built-in full waveform monitoring enables precise analysis of video signals, while 3D-LUT support lets you load custom LUTs for cinematic colour grading and creative looks. With a durable aluminium alloy frame and a protective case, the Desview D21 is built to withstand demanding professional use while delivering reliable, high-quality monitoring.
The Desview D21 is a professional broadcast monitor with support for 4K HDMI and 3G-SDI inputs, making it a key component for control rooms and live production. To take full advantage of its features in a production environment, we recommend supplementing the setup with wireless signal transmission, professional audio systems, and compatible playback devices.
Wireless Video Transmission - Systems for wireless signal transmission to the monitor’s HDMI or SDI inputs.
Audio equipment - Professional wireless microphone sets to ensure high-quality audio for the monitored video.
Readers - Studio and mobile readers that complement monitors in the broadcast and production chain.
