Atomos AO-ATOMSUMO19M ( AOATOMSUMO19M, AO ATOMSUMO19M, AO/ATOMSUMO19M) Sumo 19M 1200NIT HDR Production Monitor

The Sumo19M has a daylight-viewable 1920 x 1080 IPS screen capable of stunning 1200nit brightness, combined with the ability to display a wide range of 4K and HD sources. The Sumo19M features 10-bit processing coupled with Atomos’ unique AtomHDR engine for easy and accurate HDR monitoring. You can easily set optimal exposure when exposing for Rec.709 or HDR material. There is a comprehensive set of manufacturer-specific Log gamma settings pre-installed and multiple custom LUTs for creative looks can be stored and displayed on the Sumo19M. These LUTs are loaded via a standard 2.5 inch drive placed in an Atomos Master Caddy. The unique HDR slider allows users to rapidly examine Log images when shooting for either HDR or SDR. In SDR the slider can be used to set exposure to prevent excessive noise in shadow areas, or blown-out highlights. 


In addition, the Sumo19M has the full range of exposure and composition tools found on other Atomos 4K monitors. Waveform monitoring, zebras, 1:1 and 1:2 magnification, peaking, false colour, vectorscopes, anamorphic desqueeze and frame guides are all available at your fingertips. Display accuracy can be guaranteed over time using a i1DisplayPro probe and calibration software from colour specialists X-rite. An optional sunhood is also available which can be left on the unit and folds down for transport.


Editing Monitor

Sumo19M is just as at home in the edit suite as on-set. The color-accurate display gives the ability to grade HDR or Rec.709 productions with confidence. Edit in Log and instantly see your result in Rec.709 with 10+ stops of dynamic range displayed.  Maintain color accuracy over time with the X-rite i1DisplayPro probe. Output in HDR to HLG or PQ formats for instant preview on a compatible HDR television. Unlike a regular computer monitor, the Sumo19M directly accepts broadcast spec video signals over SDI and HDMI from your NLE. This allows for extremely accurate monitoring. Waveforms, RGB parade, vectorscope and safety guides are all available at your fingertips.


Director’s and client monitor

The large 1200nit daylight viewable 1920x1080 display will impress your directors and clients, especially with its HDR capabilities. Give them the confidence that your colors and exposures are perfectly set whether you are shooting for HDR or regular Rec.709 delivery. See Log footage with 10+ stops of dynamic range on screen by using the unique AtomHDR engine. Easily demonstrate your vision with the ability to load and display creative LUTs. Output to connected screens and devices via HDMI or HD-SDI with LUTs applied, or in HDR in HLG or PQ formats.


Gaffer, Focus puller and support crew

Take the guesswork out of technical setups and focussing your images with the large, high brightness 1920 x 1080 IPS LCD display. Don’t work with a flat, hard to see Log image. Use the preset camera profiles to quickly view footage from most Log cameras in Rec.709. Peaking makes sure that your shots are correctly focussed, whilst Waveform ensures optimal exposure to give rapid confirmation that your shots are setup correctly.


DIT Cart operator

DITs will appreciate the robust construction, multiple connections and flexible power options when using the Sumo19M on their carts. Use the comprehensive range of video monitoring tools, including waveform and vectorscope, to quickly confirm the quality of your client’s image. Use AtomHDR to see 10+ stops of dynamic range on screen from your Log material. Quickly preview Log material in Rec.709 with a LUT applied, or using one of the pre-installed manufacturer specific camera profiles.
