Stumbled on to this cable when looking up Laser as they are the distributor GTEK cables sold by JB Hifi.
I was also offered a $10 off coupon when first accessing the site.
Ordered on the 29/12/20 and they arrived today 08/01/21.
They bear an "Ultra Certified Cable" sticker but it does not feature the hologram (unlike the GTEK which did), so I cannot validate they have officially passed. Comment below quoting AVSForum suggests not. Buyer beware.
Will test them shortly but I don't run anything that is HDMI 2.1 in my setup, I just got them to use with my current setup that has HDMI 2.0 and needed eARC support.
uhoh… you used the words future proof… lol!
