These useful accessories help extend your HDMI setup on a budget

HDMI signals degrade after about 25 feet, causing flickering, pixelation, or loss, so extending a setup requires accessories. HDMI couplers link two cables and support up to 48 Gbps and 8K video, but still suffer degradation beyond 25 feet. Signal repeaters refresh the signal, reaching roughly 100 feet, while active copper or fiber-optic cables embed chips to boost transmission over longer distances.
