Question: how much bandwidth does a 4k tv use?
Answer: Streaming TV and movies in SD, HD or 4K UHD For standard definition (SD) streaming you'll need on average 2-3Mbps, for HD 5-8Mbps and for 4K UHD you'll need 25Mbps minimum, but we recommend a connection of 50Mbps to cover all scenarios (live 4K broadcasts require more speed, for example).
