Product Overview

AI-generated summary

For £57.79 ex-VAT, this StarTech HDMI “signal booster” is the kind of handy fix you buy when a setup is *almost* working — but the picture starts dropping, flickering, or refusing to lock at certain lengths. In day-to-day office and boardroom life, that’s often a cable/handshake distance issue rather than a true hardware failure, and a booster like this can be the low-effort way to stabilise things without ripping out the whole run. It’s especially useful if you’re running an HDMI lead from a laptop to a TV/projector and you’ve already tried swapping cables once and the problem persists.

That said, it’s not a magic wand. If the root cause is a bad HDMI source port, a low-quality adapter chain (especially HDMI-to-VGA/USB-C dongles), or a genuinely long/poorly terminated installation, a booster won’t always save you — it can even add another point where handshake problems show up. I’d recommend this for straightforward, practical scenarios (typical office runs where you’re just nudging signal quality), but if you’re building a critical, permanent AV install, it’s usually better value to use a purpose-built proper HDMI extender/cable solution designed for that distance rather than relying on a booster.
