Most modern Internet-capable devices come with settings or software that can restrict access to adult content.

If you can access adult content using another device on your connection, (e.g. from your PC), but not from a specific device (e.g. your TV), then it is likely there are some restrictions on the device itself. (If you cannot access adult content from any device on your home network then it is likely a restriction on your connection.)

It is not practical for us to list all the possible devices and settings here but information for setting (or more importantly, un-setting), these restrictions will be available on the device manufacturer’s website.

The best thing to do is search for your device…

“adult filters” and “parental control” are used interchangeably and may yield better results.

For example:
“remove adult filters playstation”
“remove parental control Samsung tv”
