- Summary
- GeoHN.G's AP-H21 HDMI 2.1 cable made its way onto the HDMI TEST BENCH, where both a 3.3-foot and 15-foot sample were tested using high-bandwidth signal generators. With support for full 48Gbps transmission, including 4K120 and 8K60 formats, the cables proved capable of maintaining rock-solid connections across various test conditions. Murideo’s STIX Generator confirmed stable performance even at maximum signal demands.
On the latest HDMI TEST BENCH, a Chinese manufacturer called GeoHN.G finds two lengths of its AP-H21 HDMI 2.1 Fiber Optic Cable on the bench. GeoHN.G provided the samples, sending 3.3-foot and 15-foot versions, both promising 48Gbps performance. The review includes physical measurements and evaluation, in addition to tests with Murideo's 8K Fox and Hound Test Kit and 48Gbps STIX Generator, testing its ability to establish 5 volts, while also providing stable connections for 8K 60 and 4K 120 connections. These tests encompass both 40Gbps and 48Gbps configurations.
