Thank you for the replies. I am certain it's not the HDMI itself but I will try a different port. It is an issue I only seem to have on this TV and not the others I have boxes on but there are different streams on each through the provided I use so I suppose it could be the stream service on this TV if it's not the port. It is a newer Samsung Smart TV and sometimes I wonder if the TV itself has some kind of safeguards on it for certain streaming links creating the issue but I figure that's likely a reach. I only notice it on live sports streams in high resolution.
