Posting here for some visibility. I recently went down the rabbit hole of looking for a reliable, somewhat inexpensive 48Gbps cable for connecting my XBox Series X to my LG CX tv. Luckily the xbox tests the video signial immediately, so you know right away if the cable supports at least 40Gbps or not.\n\nMy run was about 11 feet in length, so I needed something longer than the Monoprice that did work. The other cables I either returned or used elsewhere to replace old junk cables.\n\n\nCables capable of true HDMI 2.1 speeds:\nhttps:\/\/www.amazon.com\/gp\/product\/B07S1BNM7K\/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1\n^Using this one. At 16' it seems to work well even without being a powered cable.\n\nhttps:\/\/www.monoprice.com\/product?p_id=39511\n^used this temporarily, I couldn't run it through the wall and still reach\n\nCables to AVOID\nBIFALE, CAIVOV, and other off-brand names on Amazon.
