thanks for the suggestion. my patience hasn't worn thin enough yet. i'll try a few other things, but ultimately, i'll likely lasnd in the same boat you're in 🙂
I also recently acquired a new Samsung 4k TV (8 series), and encountered the same problems as reported throughout this thread - no sound and no UHD resolution, when trying to setup my new TV for the first time with a Rogers 4K cable box. This thread seems to be the leading authority online on the matter for those of us with Rogers who are having a heck of a time with the incompatibility between our TVs and the Rogers 4k cable boxes.
I wanted to report that this thread was a great help. I immediately knew which fixes would not work for me, and which ones I was more likely to try. After frustrating myself for two days trying to make things work with the equipment I had at my disposal (essentially, the stuff that came with the TV and the cable box) to no success, I sucked it up, went to BestBuy and purchased the Rocketfish 4k hdmi splitter. Everything works splendidly now! The Rocketfish splitter that has been tagged as a solution for this problem worked like a gem.
Of course, it's super frustrating that Rogers would team up with Samsung to promote their 4K services and then be incompatible with Samsung TVs, and the known problems seem to persist for months on end, at least this $64.99 splitter works, eliminates the frustration and hassles and can be counted on until Rogers and Samsung figure out a way to establish a reliable solution for this technical issue.
- I would not recommend you spend hours (days?) on the phone with a Samsung rep and then waiting for a Samsung-approved technician to come and replace your One Connect Box, unless you like doing things the long and difficult way. I also fail to see how and why this is even working for some. If Samsung made a change to the OCBs at one point, as some have claimed, that could be a reason why, but this is unverified, and why isn't it being regularly reported by those with newer TVs that they aren't having this problem then? Why are those with Bell having no issues with getting their Samsung TVs to show 4K TV? The One Connect Boxes are not the problem as far as I can tell. It seems like a communication issue between the Rogers box and the TV's One Connect Box. It's as if they're speaking different languages to one another. This is where the Rocketfish splitter comes in - it makes your TV understand the signal properly that it isn't from the cable box directly. Until the issue is solved, the splitter acts like a translator between the two.
- Why is everyone talking about expensive and unnecessary Monster hdmi cables? As long as the hdmi cables you are using are hdcp 2.2, you're good to go. The cable that comes with the Rogers 4k boxes is 2.2 compliant and should work fine as one of your two hdmi cables (you will need two if you plan to use the Rocketfish splitter). I was lucky and happened to have an extra 2.2 hdmi cable lying around unused from a new Samsung UHD PC monitor I got recently (28" UHD590). Getting an hdmi 2.2 cable (if you need another) is also much cheaper at a place like Canada Computers than at a big box store like Best Buy, although Canada Computers does not sell the Rocketfish splitter. Maybe I'm totally wrong here, and I'm sure those Monster cables are better quality for what they are, but I don't think they are related to causing or solving the issue at hand.
Hope this helps!
