Question: are all tivo bolt 4k?
Answer: TiVo says the new Bolt has 4K Netflix and YouTube apps built in, as well as HEVC and VP9 decoders to handle both sources. The Bolt box supports the HDMI 2.0 spec and HDCP 2.2 copy protection, which means it should be able to dole out 4K video at 60fps from the next generation of sources.
