I don't see an excellent improvement but I do see some. I have a 4K TV and I thought by hooking up my computer to it I would be able to stream my youtube movies in 4K but it looks like a polished 1080p. +/- the video quality being streamed.
Cut the cord and went with this device. It comes with a subscription for the guide but it's affordable for the lifetime option. Strongly recommend this - does everything your cable company offers and without their prices (and many of their channels which are mostly accessible via direct subscription)
