HDMI 2.0b and HDCP 2.2 compliant with HDR10, HDR10+, Dolby Vision, and HLG pass-through. Bi-directional wideband IR, CEC pass-through, and a 4-mode EDID DIP switch round out integration, while the compact metal enclosure and dual 5V power supplies keep installation simple.\u003c\/p\u003e","brand":"KanexPro","offers":[{"title":"Default Title","offer_id":49156216029354,"sku":"EXT-HD4KEARC-50M","price":199.95,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0724\/2966\/6474\/files\/EXT-HD4KEARC-50M-zoom1.jpg?v=1787909859","url":"https:\/\/b2b.kanexpro.com\/products\/4k-hdmi-extender-50m-with-earc-s-pdif-audio-return","provider":"KanexPro B2B","version":"1.0","type":"link"}
