The StarTech ST121HDBT20L sends an HDMI signal over a single Cat5e or Cat6 cable to a receiver up to about 230 feet away. It carries 4K at 30Hz or 1080p, so it suits running a display to another room or a distant screen without long HDMI runs. It is a plain point-to-point extender: no matrix switching, no IR passthrough and no HDBaseT certification, which separates it from pricier HDBaseT kits. Buyers who need 4K at 60Hz or control of the source from the far end should look elsewhere.

Owner feedback is limited, but the pattern is that it works reliably for straightforward 1080p and 4K30 runs over a single cable. Complaints center on the 30Hz 4K limit and the lack of remote control passthrough.
