If you want to stream anything on Max, the combination of HBO Max and Discovery+, in 4K resolution, you're going to have to pay a few extra dollars each month. HBO Max has two tiers — $10 a month if you don’t mind ads, and $16 per month if you don’t want ads. The latter gets you some shows and movies in 4K. But if you want to watch anything on Max in 4K resolution that tier — dubbed the Ultimate tier — will run $20 a month. #hbomax #warnerbrothers #discoveryplus #streaming
