The Godox GM55 is a compact, 5.5" on-camera monitor with a lightweight plastic design, 1080p touchscreen display, and HDMI input and output supporting up to DCI 4K24 and UHD 4K30 camera signals. The output allows you to connect to a wireless transmitter so other operators can monitor the image on set. The GM55 also features a headphone port and a proprietary camera control port for controlling record start/stop and other basic functions of select cameras via optional Godox control cables. The monitor comes with an L-series battery plate on the rear and offers a DC power input port for optional power cables. Additionally, a DC output port is provided for running power to select cameras from the monitor. Batteries and power cables are sold separately.

The GM55 allows you to import up to 25 3D LUTs via an SD card slot, which has a protective cover over it just as there is over the camera control port (the SD slot is for LUT import only). The extensive software features of the GM55, such as false color and vectorscope, can be adjusted by touchscreen via a simple interface with headings on the left side and adjustment points on the right. These allow you to monitor focus, exposure, and other factors in more detail. The menu can also partly be controlled by a scroll wheel on top. Six function buttons are provided on the top as well, which can be loaded with the software monitoring features of your choice for quick recall. Three 1/4"-20 mounting ports are provided, on the top, bottom, and right side, allowing for horizontal and vertical mount. A shoe mount adapter is included for attaching the monitor to your camera's hot shoe or to a cage with a shoe mount. A slim, collapsible sun hood is also included and snaps onto the monitor to block sunlight in outdoor environments.
