Ultra High Definition (UHD), also known as 4K viewing, is currently available to Astound TV customers. Watching programs in 4K quality requires a few things – a 4K TV (customer owned) and a source that provides content in Ultra HD / 4K. Certain Astound equipment powered by TiVo is capable of delivering 4K resolution programs to your TV. If you have a 4K television set and a 4K capable set-top box or 4K streaming device from Astound, you can view 4K content. To watch 4K shows available through streaming services you’ll also need an internet connection and a separate streaming subscription (like Netflix). To view Special Events channel 1526, you will need to subscribe to Signature TV.
