These Bridgee branded HDMI 2.1 cables are active cables - meaning you have to plug the specified ends into the input and outputs
They work at distances of at least 10m 4K @ 120hz - unlike 90% of HDMI 2.1 cables - certified or not
For distances over 10 feet you pretty much have to go active if you want 8K or 4K @ 120hz….
5m is $41.65 on a lightning deal, but you can also use the 20% coupon in the listing to bring it down to less than $33 which is a bargain for such a long length HDMI 2.1 cable that actually works
7.5m is $42 but thats standard pricing (after 20% coupon). No lightning deal on that one.
The 10m was also on sale @ $35 but sold out super fast.
Im using a 20m Bridgee with a projector and confirm eArc is working. Im running netflix on projector and can still play back sound on the receiver even tho its a one way cable
