I can completely understand how much of a better experience it is for you to watch your favourite channels in HD rather than SD especially when many of us have very expensive TV's that have amazing picture quality. Having to go from that quality to SD quality is pretty disappointing, to put it lightly.
I know this is not the answer you are hoping the hear but we have not been advised of any plans to broadcast CNBC in HD, at this time. We frequently update our channel offerings and within the last year, MSNBC and Fox News were both changed to HD. I am hoping that CNBC will be changed over soon.
We will keep the Community updated if there are any changes in the near future.
Thanks for taking the time to join the conversation!
