Best AV Extenders Compared in 2026

These five AV extenders are compared on interface or cable type, listed length, resolution and refresh where specified, cascade or control accessories, and price. Confirmed details vary widely, from a CAT6/CAT5 HDMI extender with an IR remote to two listings that state little beyond a transmitter and receiver configuration. Only the ATEN model confirms cascade support, and length figures are only specified for some models. Prices run from £91.16 to £510.63, so buyers should check unconfirmed specifications against their own setup before ordering.
