Thanks renojim. There's many versions of HDMI cables and I need a version that supports HDCP 2.2. I just ordered a Roku Ultra from BH Video and added an HMDI cable where the specs specifically say it supports HDCP 2.2. It's probable that the Ultra Premium Cable that comes with the unit supports 2.2, but Roku doesn't say so (that I could find).
I buy what I need, I don't buy via guessing and hoping. Got my new LG TV having the necessary specs and currently shopping for a soundbar (Definitive Technology brand so far). Everything in the AV chain (aka HDMI cable) needs to have the same capability for the quality I'm interested Thx again!
