Just purchased a new Roku TV. The HDMI connection on the TV is smaller than the current cable we have connected to our Xfinity X1 set top box. Do I need a HDMI cable with Xfinity and if so are there cables available with both the larger and smaller connections? Or an adapter? Or will I need a new box?
Are you saying that your TV uses a Micro-HDMI? I have seen/used those, but only on things like small computing devices - never on the TV side. Any chance there is some confusion between HDMI and USB? What is the model of the TV? Can you post a picture?
HDMI is an international standard. If the cable doesn't fit, it isn't an HDMI cable, or the jack isn't HDMI. I'm certain the jacks in the TV are HDMI, but I'd have to see the cable that you're attempting to connect to say for certain what it is.
As mentioned, there are mini-HDMI connectors, but the only devices I've ever seen them used is on computers. And there's an obvious difference in size between the two. It almost sounds like you might have a Display Port or Firewire cable, although why Xfinity would have such a connection is beyond me.
