Well, like all things made by people, there are variances between individual examples (tolerance, so to speak, in engineering jargon).
So it could be, regardless of anything, your specific cables would pass the Premium Certified testing process. All the certification does is guarantee that a cable can pass the necessary bandwidth. And, if you find that it doesn't, then you get to return it as defective.
It's more a peace of mind kind of thing. Without having certified cables the problem could be your cables or it could be the Roku. With the premium certified cable it's either a defective cable or the Roku. I have had all kinds of problems with defective cables so I am a bit paranoid. In fact, I replaced all my HDMI cables recently because my PS4 started misbehaving (sparkles, blanking out, that kind of thing). No problems since I replaced them.
The only reason I know any of this is because it's a huge deal to have the proper cables on the Oppo 203 forum. So many people have had problems with the player that have said, "My cable works fine, I've had it for years and never had any problems! In fact, they worked yesterday." They complain and complain about the problems refusing to do anything about the cable. Then they change out the cable for a premium certified one and we never hear another complaint from them. Hmm, wonder why that would be...;-)?
The premium certified Monoprice cables get recommended. Apparently, Amazon has a $6 premium certified cable in stock every once in a while. For $6 it's worth a shot. Remember, it's not an expensive cable that matters - only that it be premium certified.
