HBO Max has now hosted or will host, close to 30 titles streaming in 4k Ultra HD. All of the titles feature High Dynamic Range capability delivered via Dolby Vision or HDR10. And, The majority of the movies offer Dolby Atmos audio for an immersive sound experience. If not, the default is Dolby 5.1 channels.
Up and coming movies expected to stream in 4k with Dolby Vision/HDR10 include Dune (Oct. 22) and The Batman (coming 2021).
Now, we should note some of the titles are currently in the pay window time period during which the movie has left HBO Max (after the month-long “Same Day WB Premieres” window) and is only available for purchase (in Digital or Disc) or rent (at a premium cost).
An example is The Suicide Squad that premiered on August 6 but is no longer available on HBO Max. However, as we’ve seen with other titles such as Judas and the Black Messiah and Those Who Wish Me Dead it will likely return sometime after the physical media releases and in 4k.
