Software updates

The process is simple and easy to start.

HDMI cables are the best option to use Roku smart devices with TV.

In case you were using an RCA cable with a Roku streaming device, make sure you change it with an HDMI cable.

It’s because they don’t overheat and provide the best visuals.

However, if you’re already using an HDMI cable but still having an issue with the blue light.
