HBO Max is completing its transformation into Warner Bros. Discovery’s “Max” streaming service today, and it’s launching with a new tier especially made for 4K ultra HD viewing. The Ultimate Ad-Free tier will set you back $20 a month or $200 if you’re paying for a whole year, making it the service’s most expensive subscription option yet. A subscription will give you access to over 1,000 4K movies and TV show episodes, which is nearly eight times more than previously available 4K content. It will also give you the ability to stream on up to four devices at the same time and to store up to 100 offline downloads.

Ultimate Ad-Free’s arrival, however, spells the end of 4K availability if you stick to regular ad-free subscription. According to the company’s announcement, “existing HBO Max subscribers will still have access to their current plan features for a minimum of six months following launch.” After that, you’ll no longer be able to stream 4K content on the service. To note, Warner Bros. raised its subscription prices in January, so you now have to pay $16 a month for the ad-free tier and $10 for the ad-supported one. 

For the Ultimate Ad-Free tier, Dolby Atmos and Vision will also be available for select content and devices. The company plans to keep growing its 4K library every month going forward, but for now, those 1,000 ultra HD shows and movies you can stream with a subscription include Game of Thrones, House of the Dragon, The Last of Us, the Harry Potter movies, The Lord of the Rings trilogy, The Dark Knight trilogy and The Matrix films. Further, all Warner Bros. movies released this year and in the future will be added to the tier’s 4K library when they arrive on Max.
