PORTKEYS BM5 IV Overview

Use the PORTKEYS BM5IV 5.5" HDMI/SDI Touchscreen Monitor to monitor your image and focus accurately, no matter if you're shooting on location or in the studio. This ultrabright 2000 cd/m² onboard monitor features a wide color gamut, a durable aluminum build, and both HDMI and 3G-SDI video inputs and outputs. It supports HDMI/SDI signal conversion and can output 3D LUTs via its SDI output port. Wired control is available for select RED, Sony, Blackmagic Design, Canon, Panasonic, and Z CAM cameras, as well as the Tilta Nucleus-M wireless lens motors.
Flexible Color Controls
The BM5IV uses three color gamuts to properly calibrate your image: 100% REC.709, 85% P3-DCI, and 85% P3-D65. You can manually select your Log mode, toggle Log false color, and select your own custom false color from 77 colors and 15 different segments. The monitor is factory calibrated with the option for users to create a 3D calibration LUT and an X-Rite color probe.
CINEFORM OS
CINEFORM OS powers the monitor and allows you to configure settings to suit your workflow. Import two sets of custom color calibration files, create seven custom control pages, and save it all to the included micro-USB drive for import to another monitor and streamline your workflow.
Dual-Screen Monitoring
When taking in multiple camera signals via the HDMI and SDI input ports, you can select different dual-screen monitoring configurations to view both images simultaneously. Choose between horizontal to vertical crop, picture-in-picture, dual vertical, dual horizontal, and vertical/horizontal split views.
Connectivity
This upgraded BM5IV monitor features the same HDMI input, SDI input, and SDI output ports found on the previous model with the addition of an HDMI output, allowing you to convert signals with ease. The HDMI ports can support up to 4K60 video, while the SDI ports can support up to 1080p60 video. A USB-A port helps facilitate firmware updates and uploads 3D LUTs to the monitor.
Wired Camera & Motor Control
A micro-USB remote connection facilitates camera control with select camera models from RED, Sony, Blackmagic Design, Canon, Panasonic, and Z CAM using separately available cables. The BM5IV can also be used in tandem with your Tilta Nucleus N/M wireless focus system using its UART port for calibration and limit setting.
Multiple Power Options
Use the 4-pin interface and included D-Tap cable to connect compatible power sources directly to the monitor. A built-in NP-F battery plate supports compatible batteries.
Robust Design
The monitor is constructed of durable aluminum alloy to withstand the rigors of production. The integrated fan can be set to switch to its lowest setting once the recording is toggled to minimize audio distortion.
