It is the right choice for gaming theaters, esports rooms and mixed-resolution commercial installs where high-refresh signal integrity and per-output scaling matter more than raw port count.\u003c\/p\u003e\u003cp\u003eEach of the four outputs carries the complete HDMI 2.1 gaming feature set — VRR, ALLM, QMS, QFT and SBTM — with HDR10, HDR10+, Dolby Vision and HLG pass-through, plus independent optical S\/PDIF and balanced analog breakout for de-embedding audio to a processor or zone amp. Advanced EDID management with 36 defined, 3 user and 4 copy modes keeps mixed-source, mixed-display systems stable, and the matrix drops into any control system over front-panel buttons, IR, RS-232 or a TCP\/IP Web GUI. Its single strongest advantage is doing all of this at a true 48Gbps — not the 40Gbps of many 8K units — while downscaling per output so legacy 4K and 1080p displays share the same routing fabric as the 8K reference screen, without a separate scaler in the rack.\u003c\/p\u003e","brand":"KanexPro","offers":[{"title":"Default Title","offer_id":49316805050538,"sku":"MMX-4X4-48G","price":1499.95,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0724\/2966\/6474\/files\/MMX-4X4-48G-zoom1.png?v=1790143443","url":"https:\/\/b2b.kanexpro.com\/products\/mmx-4x4-48g","provider":"KanexPro B2B","version":"1.0","type":"link"}
