openGear 4K/UltraHD-SDI to 3G-SDI Down-Converter with DashBoard support
OG-4K2HD is an openGear card that down-converts professional 3G-SDI 4K/UltraHD signals to HD resolution using AJA’s high-quality scaling for cost-effective monitoring and conversion. OG-4K2HD’s HD-SDI and HDMI outputs are live simultaneously, producing fantastic-looking HD images for on set monitoring or direct-to-air broadcast.
The OG-4K2HD down-converts professional 3G-SDI 4K/UltraHD signals to HD resolution over 3G-SDI and HDMI using AJA’s high quality scaling for cost effective monitoring and conversion. OG-4K2HD’s HD-SDI and HDMI outputs are both live all the time for on-set monitoring or direct-to-air broadcast with support for up to 50/60p. OG-4K2HD’s configuration options can extract an HD resolution image from the 4K input to provide a 1:1 pixel image for 4K focus checks on HD displays. Configuration can be set remotely via DashBoard network control software
OG-4K2HD supports high frame rate (HFR) 4K/UltraHD inputs at 50 and 60fps and converts to HD outputs at 50 and 60fps for accurate viewing. OG-4K2HD’s configuration options allow extraction of an HD resolution image from the 4K input to provide a one-to-one pixel image for 4K focus checks on HD displays.
Designed for use in high-density openGear’s 2RU frames including AJA’s OG-3-FR 2RU frame, new DashBoard Software support on Windows®, macOS® and Linux® offers remote control and monitoring of the openGear architecture and provides convenient and industry-standard configuration, monitoring and control options over a PC or local network.

The latest generation of affordable 4K monitors utilize an HDMI 2.0 connection, which allows a full 4K signal to be passed over a single cable. Typical professional 4K workflows use four SDI cables to carry the full resolution image, making it difficult to incorporate these newer monitors. OG-Hi5-4K-Plus is an easy-to-use converter that bridges the gap between these two worlds for seamless integration.
Real time downconversion
OG-4K2HD uses real time processing and AJA’s high-quality scaling algorithms to downconvert professional 4K or UltraHD signals using 4× SDI connections to HD resolution, producing fantastic-looking HD images for on set monitoring or direct-to-air broadcast.
Simultaneous HD-SDI and HDMI outputs
OG-4K2HD’s HD-SDI and HDMI outputs are live all the time, allowing use of both professional SDI monitors as well as low-cost HDMI monitors simultaneously. No matter what monitors you have on hand, OG-4K2HD can use them for on the spot 4K viewing.
High frame rate support
Many 4K productions are opting for higher frame rates of 50 and 60fps. OG-4K2HD supports high frame rate (HFR) 4K inputs and converts the HD output to a matching frame rate for accurate viewing so what you shoot is what you see.
OG-4K2HD can be configured to extract an HD resolution center cut from the 4K input. This provides a one-to-one pixel image that can be used to check focus on 4K shoots without the need for a full 4K monitor.
The openGear standard ensures that AJA cards will be compatible with other openGear products from certified openGear partners. With a growing list of products, openGear is the future of rackframe products.
The modular rear panel allows custom I/O connections per card (included with individual cards).
The optional redundant power supply provides a secondary power source in the event of a primary power failure.
A standard Ethernet connection allows the frame to be accessed via the Dashboard application for overall frame communication. Optional per-card Ethernet access can be installed in the frame for advanced communication with compatible openGear cards.
