Unigraf presents a compact overview of its video interface test tools for HDMI, DisplayPort and USB-C validation, with Reed showing how the Finnish company’s instruments are used for compliance test systems, functional debugging and automated production checks. The focus is on real signal behavior rather than just image output: link training, timing, sink/source capability reporting, FRL, TMDS, HDCP, DSC, VRR, eARC, USB Power Delivery and DisplayPort Alt Mode all become measurable parts of the engineering workflow. unigraf.fi

HDMI® Technology is the foundation for the worldwide ecosystem of HDMI-connected devices; integrated with displays, set-top boxes, laptops, audio video receivers and other product types. Because of this global usage, manufacturers, resellers, integrators and consumers must be assured that their HDMI® products work seamlessly together and deliver the best possible performance by sourcing products from licensed HDMI Adopters or authorized resellers. For HDMI Cables, consumers can look for the official HDMI® Cable Certification Labels on packaging. Innovation continues with the latest HDMI 2.2 Specification that supports higher 96Gbps bandwidth and next-gen HDMI Fixed Rate Link technology to provide optimal audio and video for a wide range of device applications. Higher resolutions and refresh rates are supported, including up to 12K@120 and 16K@60. Additionally, more high-quality options are supported, including uncompressed full chroma formats such as 8K@60/4:4:4 and 4K@240/4:4:4 at 10-bit and 12-bit color.

The UCD-422 Gen2 is Unigraf’s HDMI 2.1 test platform, aimed at HDMI CTS work and deeper functional verification around high-bandwidth video links. For developers of TVs, monitors, graphics hardware, media players or embedded display systems, this kind of generator/analyzer can help validate HDMI 2.1b behavior up to FRL rates, including modes such as 8K60 or 10K30 without DSC, plus features like FEC, VRR, QMS, ALLM, HDR-related testing and HDCP 1.4/2.3 workflow.
The UCD-500 Gen3 shown in the interview is positioned for DisplayPort 2.1 testing, where UHBR link rates, Link Layer CTS, DSC, FEC, LTTPR, Adaptive Sync and USB-C/DisplayPort connector behavior matter for next-generation GPUs, monitors, docks and laptops. The software preview shown in the demo is not just a simple video window; it reflects how the analyzer can expose link training state, received capabilities, supported timings and the practical negotiation between source and sink during DP or HDMI operation.
The UTC-274 is the production-oriented USB-C tester in the lineup, designed especially for DisplayPort Alternate Mode devices such as laptops, docking stations and USB-C video products. Its role is more factory and automation focused: checking connector pin integrity, DP Alt Mode, USB 2.0/USB 3.2 behavior, USB4 mode checks, Power Delivery 3.1, EPR-related functions and repeatable test scripting through SDK/Python workflows. Filmed at Display Week 2026 in Los Angeles, the discussion also touches on HDMI 2.2, where 24Gbps-per-lane signaling would require new hardware rather than a simple firmware or module swap.
