Atomos Sumo PRO-19 4K Production Monitor In More Detail

19-inch 4K HDR display

The Sumo PRO-19 features a 19-inch touchscreen production monitor with a resolution of 3840 x 2160 and a peak brightness of 1200 nits. It covers 100% Rec.709, 99% DCI-P3 and 99% NTSC, supporting HDR monitoring and log workflows used in professional video production.

The display supports log to LUT viewing with compatibility for 3D LUTs and .cube files. This allows crews to monitor a graded image while recording log footage, maintaining consistency between capture and post-production.

Multi-camera monitoring and switching

The unit accepts up to four video inputs simultaneously and provides quad-view monitoring or single input full screen. Each feed can be monitored independently or within a multi-camera layout, supporting live production and broadcast environments.

A fifth program output can be generated, allowing switching between inputs for live output or recording. The selected program feed is available via SDI or HDMI output for downstream devices.

Recording formats

Recording supports Apple ProRes, ProRes RAW and Avid DNx formats, with up to 12-bit capture depending on source. Media options include CFexpress Type B cards or external USB-C storage devices.

The system records up to four ISO feeds while simultaneously capturing a program output, supporting flexible editing and post-production workflows.

Professional Connectivity and I/O

The Sumo PRO-19 includes 2 x 12G-SDI inputs, 2 x 3G-SDI inputs, 12G-SDI output and HDMI input and output. These connections support up to 4Kp60 signals, with loop-through and playback output options available.

Audio is handled via XLR inputs with selectable 48V phantom power, alongside XLR outputs for monitoring. A sync input allows reference locking for playback workflows, and Gigabit Ethernet supports network-based production setups.

Timecode and synchronisation

AirGlu technology provides wireless timecode sync using RF and Bluetooth. This allows cameras, audio recorders and monitors to maintain aligned timecode without physical connections.

This supports multi-camera productions where consistent timing across devices is required.

Monitoring tools

A full suite of monitoring tools is included, such as EL Zone false colour, waveform, vectorscope, RGB parade, zebras and focus peaking. These tools support exposure control, colour accuracy and focus confirmation directly on the monitor.

Additional tools include frame guides, grid overlays and anamorphic desqueeze, supporting a wide range of shooting formats and framing requirements.

Workflow integration

Integrated Wi-Fi and Ethernet support direct upload to cloud services including ATOMOSphere, Frame.io and Dropbox. This enables camera-to-cloud workflows for remote review and collaboration.

Playback functionality allows immediate review of recorded footage on set, supporting decision-making without moving media to external systems.

Frequently Asked Questions

Can the display be calibrated?

Yes, the production monitor supports calibration using compatible Calibrite devices via a PC or Mac connection.

Does the Sumo PRO-19 support LUTs?

Yes, it supports real-time LUT preview and allows custom .cube LUTs to be loaded from CFexpress or USB-C storage.
