Technically you are right. However a significant percentage of HDMI cables sold as ‘High Speed HDMI With Ethernet’ cable, capable of doing 4K 60 etc, are in fact not delivering what they’re promising. So if it’s a Monster cable, it will surely do what it says. For many ‘white label’ cables from China that doesn’t apply. So a lot of issues reported to us, artifacts on screen for example, are caused by cables not suited for 4K 60Hz. 

For that reason the HDMI organization has introduced a new ‘Premium’ certification program for cables, ensuring that they can do 4K @ 60Hz, BT.2020 and HDR. See: http://www.hdmi.org/manufacturer/premiumcable/Premium_HDMI_Cable_Certification_Program.aspx 

So our ‘HDMI 2.0 cable’ is a Premium certified cable, guaranteed to deliver the latest features as mentioned above.
