Best HDMI Extenders

One specification decides everything here, and it is the resolution and refresh pair written as 4K at 30Hz, 4K at 60Hz, or 1080p at 60Hz. Those are different products rather than grades of the same one, and 4K at 30Hz is the compromise that catches buyers out, because film at 24 frames looks fine over it while a games console or a computer desktop feels visibly stuttery. If the source is a current console or a PC, only 4K at 60Hz will do. Distance comes next, and the honest figures cluster around 164 to 165 feet over a single Cat6 run with some kits reaching 230 feet, where the cable category is part of the specification rather than a suggestion, since Cat5e often carries 1080p happily and fails at 4K. Three acronyms are worth understanding because each saves real trouble. PoC or PoE powers the far receiver down the same cable, so you need no socket behind the distant display. EDID handling lets the source read that display's capabilities and prevents the handshake failures that appear as a black screen. IR passthrough carries remote commands back to the equipment rack. A loop out at the transmitter feeds a second local screen. Splitter versions fan one input out to as many as eight receivers, which is a different job from point to point extension.
