The Silkland Ultra High-Speed 2.1 Cable checks all the boxes! Trust me!! Unbeatable price for this distance and quality of cable! Being able to run my 4K up to 240Hz is amazing and the cable itself looks great. Feels durable without being overly bulky in size (like some of older cables I have). Compatible with my Xbox Series X and my RTX4080. Tested eARC with my TV and Soundbar and all functions worked fine. HDR and Dolby Atmos passed with flying colors!Seriously, this cable is the one you've been looking for - stop searching and just buy it to stop all the headaches!stinson
