BZBGear BG-AVTPG-MINI Handheld HDMI Test Generator and Analyzer

The BG-AVTPG-MINI generates and analyzes HDMI up to 4096 x 2160 at 60 Hz, at 4:4:4 8-bit or 4:2:0 16-bit HDR, and is HDCP 1.4 and 2.2 compliant. It is the tool for walking a building with a display or a cable in question rather than bringing the rack to the bench.

Three test patterns cover signal quality and stability checks, and the color depth is adjustable so a display's real limits show up. The rechargeable battery runs about three hours, the case is metal, and firmware and charging both go through the micro-USB port.
