The Gratical HD EVF is Zacuto's flagship model

The original! Feature rich, versatile, future-proof, and time tested, the Gratical HD is the ultimate choice for the consummate professional. Designed to fit smoothly into a filmmaker’s workflow both on-the-go and in the studio. The Gratical HD Micro-OLED EVF offers a full suite of power, mounting, inputs/outputs, and feature options. If you’re looking for a one-stop product to cover all your current and future needs, the Gratical HD is the model for you.

As with all Zacuto's Gratical electronic viewfinder models, the Gratical HD starts with a 5.4 million pixel micro-OLED display, high quality precision optics with a built in diopter, and a powerful FPGA dual core processor.

Micro-OLED Display

The Gratical HD has a Zacuto designed Micro-OLED 0.61” diagonal display with 5.4 million pixels to provide a hugely expanded contrast range. With Micro-OLED screens, each pixel is lit individually so that when one is turned off there is true black. This makes for a wider contrast range and more vibrant colors for a vivid, enhanced picture.

Connections & Compatibility

Incorporates an HD-SDI input and output and an HDMI input and output with weather resistant covers to prevent moisture or debris from getting in the open ports.

  • HDMI

    1.4b compliant, resolutions up to 1080p/60, loop out
  • HD-SDI

    Resolutions up to 1080p/60, loop out
  • Cross Conversion

    HDMI to HD-SDI, independent LUT on output stream


The Gratical HD is powered by a state-of-the-art FPGA dual core processor that supports a host of professional features including HDMI and SDI with simultaneous cross-conversion, Vectorscope, Waveform (3D), Histogram, Timecode, LUT import, creating, and editing, and more. (See full feature list below.) The processing power of the Zacuto Gratical HD far surpasses all other EVF units on the market.


The built-in USB port is used for downloading firmware updates and additions. Gratical HD users have access to all future updates and additions free of charge for life. Zacuto is constantly working on improving workability of current features and creating new features to keep your EVF up to date and future proof. Zacuto often takes user requests into consideration. If there’s something you’d like to see included, contact us to make a suggestion. You could see it in the next firmware!

Power & Mounting

Self powered with an included LP-E6 battery, the Gratical HD has a run time of about 4 hours. You can also use a LP-E6 to d-tap cable (like this one) and power the unit off system batteries for a much longer run time. Mounting options include both a ¼ 20 screw hole underneath the EVF and a ¼ 20 rosette on the side. Attach your electronic viewfinder with an arm or Zacuto Axis Mini as part of a Zacuto Next Generation Recoil Rig.
