Description
UCD-422 is a video generator and analyzer for testing HDMI 2.1 interface up to 10K video modes. Resolutions supported are 4K@120Hz, 8K@60Hz (requires YCbCr 4:2:0) and 10K@30Hz with uncompressed video. UCD-422 offers support for FEC, DSC Sink & Source, and eARC. HDCP 1.4 and HDCP 2.3 are also supported.
Approved HDR10+ Display Device Test Tool
Unigraf’s HDR 10+ Display Device Test License (MT6675), allows HDR 10+ adopters to generate HDR 10+ specific patterns that are required by HDR 10+ LLC to certify Sink devices such as TVs and Monitors for HDR 10+.
Unigraf’s solution integrates Klein K-10A colorimeter for automated testing of HDR 10+ Display Device tests allowing users to set and play the patterns without having to manually measure luminance values of HDR 10+ patterns. Users that do not have Klein K-10A colorimeter will be able to manually record measured luminance values into the software GUI. This solution is easy to use and reduces the time required to run HDR 10 Display Device certification tests.
Fixed Rate Link / TMDS Support
Fixed Rate Link (FRL) is the link data transfer method introduced in HDMI 2.1. FRL replaces the current TMDS but HDMI 2.1 specification still requires support for TMDS for backwards compatibility with billions of HDMI 1.4b and 2.0 devices in the world. (Source: HDMI)
The UCD-422 can identify interoperability issues on FRL capable source and sink devices. Users can verify if an image is captured correctly on the UCD Console when testing source devices using different FRL modes. Check any FRL rate such as 3 Gb/s, 6 Gb/s, 8 Gb/s, 10 Gb/s and 12 Gb/s. Conduct link training to check if your sink or source is capable of transmitting video at different timings through TMDS/FRL.
Unique Features
Enhanced Gaming Features
Check the availability of enhanced gaming features on sink and source devices that support Variable Refresh Rate (VRR) and Auto Low Latency Mode (ALLM). Check full range of VRR from 40 Hz to 120 Hz. Ready-made scenarios for ALLM testing are available in the UCD-422. By supporting these enhanced gaming features, the UCD-422 makes for a complete test tool for game console and display manufacturers.
Create Your Own Scenarios
Any video format, audio, frame rate, video timing, and infoframes including time stamps can be played or captured by UCD-422. There are no restrictions on the output of video formats.
UCD Console GUI
UCD Console is Unigraf’s common Graphical User Interface (GUI) for all UCD series products. UCD Console enables users to access all test features of the UCD-422. It provides users with a flexible way of navigating between its sink and source roles and functionalities of each role.
Available functionalities include preview windows for captured video and audio, video and audio pattern generator, data logger for AUX and metadata content, link and DPCD register monitoring and control dialogs, EDID editor, HDCP status and control functions etc.
UCD Console is delivered with ready-made test sets (e.g. content check-sum tests and Link Training tests) for testing HDMI Sinks and Sources.
