Product Overview

AI-generated summary

StarTech’s HDMI over CAT6 with power-over-cable at ~100m is one of those “it saves you a headache” products—assuming your environment is stable and you’re deploying a clean point-to-point link. For the right buyer, it’s great value versus running HDMI and power separately: you get a single CAT6 run that handles both signal and power, which is especially handy in offices, meeting rooms, and reception areas where you don’t want to start re-plumbing or dealing with multiple adapters. At £375 ex-VAT, I’d only consider it if you actually need the distance and you want something that’s predictable without tinkering.

That said, I wouldn’t buy this for experimental setups or if you’re expecting it to “fix” a bad video source. HDMI extenders live and die by signal quality—CPU/GPU output quirks, HDCP handshakes, and whether your CAT6 is truly up to spec (good terminations matter). Also, if you’re extending across multiple patch points or in a noisy cable path, performance can get hit, and you may end up spending more time troubleshooting than the savings were worth. If you need long, reliable runs in a straightforward installation with good cabling, this is a solid buy; if not, you’d be better off validating the cable route/source compatibility first or budgeting for a more robust system.
