Watch in 4K HDR

You can watch the following movie premieres in 4K Ultra HD, HDR 10, Dolby Vision and Dolby Atmos on select devices:

• Godzilla vs. Kong (streaming through April 30, 2021)
• Mortal Kombat (starting on April 23, 2021)
• Zack Snyder’s Justice League

Movies available in 4K HDR are also available in HD on all supported devices.

HBO Max will play the highest quality audio and video available for your device.

What you need

Here's what you need to stream in 4K HDR with Dolby Atmos audio:

• 4K HDR TV that displays Dolby Vision or HDR10
• Supported 4K HDR streaming device
• High speed internet (25 Mbps or higher, 50+ Mbps is recommended)
• Dolby Atmos-capable sound system

All devices must support HDMI 2.0 and HDCP 2.2 (your TV, media player, audio/video receiver, cables, adapters, and any other connected devices).

If you have the above requirements and the title is available in 4K, HBO Max should automatically play the title in 4K HDR. HBO Max automatically adjusts the video quality based on your network bandwidth and connection speed (you can't manually adjust the resolution in HBO Max).

If the title doesn't appear to play in 4K HDR with Dolby Atmos, here are a few things you can try:

Step 1: Check your devices

Make sure your TV supports 4K resolution and HDR 10. To do this, find your TV model number and then search the internet for info about your TV's resolution.

Supported 4K devices

You can watch in 4K on the following devices:

• Amazon Fire TV Stick 4K and Fire TV Cube
• Android TVs, including: AT&T Streaming Box
• Apple TV 4K
• Google Chromecast Ultra and Chromecast with Google TV
• Roku Ultra 4800x, Roku 4k TVs, Roku Premiere, and Roku Streaming Stick+
• Xfinity X1 (Xi6) and Flex

We’re working to add more devices and 4K movies in the future.

Note  Dolby Atmos is not available with Chromecast with Google TV, Roku Premiere, and Roku Streaming Stick+.

Step 2: Update HBO Max

Make sure you have the latest version of HBO Max. To do this, open the app store on your device and search for HBO Max. If there's an app update available, choose to update or download the update. For additional help, see Step 1 on the Troubleshoot TV page.

Step 3: Test your internet speed

Make sure your internet download speed is at least 25 Mbps. HBO Max automatically adjusts the video quality based on the download speed of your connection. If your download speed is less than 25 Mbps, the show or movie won't stream in 4K HDR.

Higher speeds will provide more consistent 4K HDR streaming. For the best experience, we recommend a download speed of 50+ Mbps on your streaming device.

Test your connection speed

To find out how to test your connection speed, go to Troubleshoot HBO Max on your TV and choose your TV device.

Try a wired connection

If you’re experiencing slow or inconsistent speeds over WiFi, try connecting your streaming device to your router using an Ethernet cable.

Reduce activity on your network

If other people are using the same network, ask them to temporarily pause their activity. This will allocate as much bandwidth as possible for streaming.

Step 4: Try another cable or HDMI port

If you're using a streaming player (e.g. Apple TV):

• Make sure you're using a High-Speed 4K HDMI cable.
• Make sure your HDMI cable is plugged into a HDCP 2.2 compatible HDMI port on your TV or audio/video receiver. HDCP 2.2 may not be supported by all of the HDMI ports on your TV (refer to your owner's manual to find out which HDMI port is HDCP 2.2 compatible).
• Bypass your audio video receiver, HDMI switch, or sound bar, by connecting your streaming device directly to your TV.

If you're getting an HDCP error, try the TV steps in this article: I'm getting an HDCP error.

Step 5: Check your display settings

When it comes to TV settings, we suggest turning off motion smoothing. The steps for doing this vary depending on your TV model. Also, you may want to set your picture mode to Cinema or Movie mode.
