Why Can’t I Turn Off Closed Captioning on My Roku Device?
There are a few reasons your Roku may be showing closed captioning when you aren’t expecting it. The most obvious is that system captions were turned on intentionally by someone other than you. This might be another user of your Roku, but it could also happen during a channel or system upgrade.
In addition, each channel on your Roku device can also have its own closed captioning settings which override the system-level settings. So setting captions off at the system level, but on at the channel level, would also account for their unexpected display. Someone may have even inadvertently turned them on for your current content when using the playback controls.
How to Turn Off Closed Captioning on Roku
You can turn off closed captions on your Roku device for good with a couple of simple steps. Start by checking the system-wide settings, or alternately in the channel’s settings. Finally, if these seem to be set correctly, you can always reset your device.
