How to change the display refresh rate to match the native format of each movie, video or TV show

Background

Current generation Roku® streaming players are designed to output all content at a display refresh rate of 60 fps. If you prefer, your 4K capable Roku player can be configured to output the native format of each movie, video or TV show by enabling the auto-adjust display refresh rate setting.

  • Note: The auto-adjust display refresh rate setting is not available on Roku players that do not support 4K. You can check the product comparison chart to see which products support 4K Ultra HD up to 60fps.

What is display refresh rate?

When playing video, “fps” refers to frames per second, also known as frame rate, or display refresh rate. Each frame is a still image; displaying frames in quick succession creates the illusion of motion or animation. The more frames per second, the smoother the motion appears.

What is native format?

Hollywood movies are commonly filmed at 24fps, YouTube videos are often shot at 25fps, and TV shows are generally filmed at 30fps. This display rate is specific to each type of content, and is known as the native format.

How do I configure the display refresh rate?

The auto-adjust display refresh rate setting can be enabled or disabled from the settings menu on your 4K capable Roku player. The setting will NOT change when your Roku player reboots or when the software updates.

  1. Press the Home button home on your Roku remote.
  2. Scroll up or down and select Settings.
  3. Select System and then select Advanced system settings.
  4. Select Advanced display settings.
  5. Select Auto-adjust display refresh rate and choose from the following:
    • Enabled – Your Roku player will automatically switch to the native format of the movie, video or TV show when playback begins.

      • Note: Due to video mode changes by your TV, the picture may flash to black when starting and stopping playback.

    • Disabled – Your Roku player will output ALL content at 60fps.

Why is video jerky when watching a movie or video?

When auto-adjust display refresh rate is disabled, your 4K capable Roku player outputs all content at 60fps. A movie filmed at 24fps, or a video shot at 25fps may exhibit subtle jerkiness due to the conversion to 60fps. To avoid this behavior, follow the steps listed above and enable auto-adjust display refresh rate.

Why do I see a black flash when starting a movie, video or TV show?

When auto-adjust display refresh rate is enabled, your 4K capable Roku player switches to 24fps, 25fps, or 30fps during playback of most movies, videos or TV shows. Each time the display rate changes like this, your TV must change video modes which may cause a black flash. To avoid this behavior, follow the steps listed above and disable auto-adjust display refresh rate.
