If Roku fails to display channels in full screen, and you only see a quadrant in the upper corner or in the middle of the screen, keep on reading this guide to learn why the device is not displaying your channels properly.
How to Fix Roku Full-Screen Issues
Check your display settings
One frequent cause of this issue is that you did not set up the correct resolution and frame rate settings on your device.
If you’re using customized settings, go back to auto-detect mode. This allows Roku to automatically detect the correct resolution and frame rate settings that your TV supports.
- Take your Roku remote and press the Home button
- Select Settings → Display type
- Choose Auto-detect and let Roku analyze your HDMI connection
- There are two possible results:
- Roku detects your TV display type is supported
- The device is unable to detect your TV configuration and throws an error message that you can choose to ignore and force the connection.
In most cases, Roku should be able to detect the capabilities of your TV. Enabling the auto-detect feature should be enough to solve this problem for most users.
Check your HDMI connection
Not being able to watch full-screen channels on Roku may be because the signal that your TV is getting is not strong enough.
Check your TV settings and try to optimize them. Or remove the HDMI cable, swap the ends, and reconnect them to your device.
Also, try a different HDMI input and check if you notice any improvements.
Check for updates
Installing the latest system updates may help you to fix this problem.
- Go to Settings and select System
- Then select Check for updates
- Hit the Check now button to see if there’s a new system update version pending and install it.
Factory reset the device
If nothing worked, try performing a factory reset as a last resort. Keep in mind this will clear absolutely all the data from your device. It will be as if you bought a new Roku device.
- Go to Settings → System
- Select Advanced system settings
- Choose Factory reset.
The troubleshooting solutions listed in this guide may not yield positive results for all the Roku users experiencing this annoying full-screen issue.
