Reduce data usage while watching on Roku

If you are experiencing buffering or simply wish to not need as much bandwidth when watching videos , you can configure your Roku to use a lower video quality by default.
With your Roku device on, press the Home button on your Roku remote control. Navigate to Settings > Display type. Deselect Auto-Detect, then select your desired video resolution rate; lower resolutions will be lower in video quality but will reduce the amount of data required to playback.
