Watch Max in 4K UHD & HDR10 or Dolby Vision

You can watch select titles in 4K UHD with HDR10 or Dolby Vision on select devices with the Ultimate Ad-Free plan. To find out if a title is available in 4K UHD with HDR10 or Dolby Vision, choose the show or movie in Max and then look for 4K UHD, HDR10, or Dolby Vision on the details screen.

Note 4K UHD, HDR, and Dolby Atmos availability depends on your plan and device.

Max automatically plays the highest quality video available for your device and subscription plan. Titles available in 4K UHD are also available in HD on all supported devices.

For info about Dolby Atmos, go to Max audio quality.

What you need

To stream in 4K UHD and HDR10 or Dolby Vision:

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 UHD, Max should automatically play the title in 4K UHD. Max adjusts the video quality based on your network bandwidth and connection speed (you can't manually adjust the resolution in Max).

If you're having trouble streaming in 4K UHD resolution, here are some things to try:

Check your devices

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

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.

For more display suggestions, find your streaming device below.

Amazon Fire TV 4K devices

Check your Amazon Fire TV display settings. Here's how:

  1. Start watching a 4K movie for 1 minute.

Check your internet speed

Make sure your internet download speed is at least 25 Mbps. 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.

Higher speeds will provide more consistent 4K streaming. For the best experience, we recommend a download speed of 50+ Mbps on your streaming device. To find out how to test your connection speed, go to the Max buffering page.

Try a wired connection: If you experience slow or inconsistent speeds over Wi-Fi, connect 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.

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 a 'There's a problem with your device setup' error, try HDMI troubleshooting.

Screen too dark?

If live sports or movies in HDR or Dolby Vision are too dark, do one of the following on your TV or streaming player:

  • Turn up the screen brightness.
  • Turn off HDR.

If you need help finding the steps for your TV device, search the internet for "adjust brightness" + your device (e.g., adjust brightness Samsung TV), or “turn off HDR" + your device (e.g., turn off HDR Apple TV).
