Add-on for TV to allow tablet "mirroring"?

[clockworks]

I've got 2 Samsung TVs which allow me to "beam" Youtube content from my Samsung and Huawei tablets. I find this method of selecting and watching music videos much easier than navigating using the TVs' own apps - "typing" with the remote is a real pain.

A friend has a Bush smart TV, and I can't "beam" from a tablet to the TV - it doesn't show up as an available target. Watching her struggle with typing on the the TV remote is painful - she gets annoyed with it.

I guess this feature is only found on Samsung TVs?

Is there a simple device that can be plugged into the TV's HDMI port that will allow "beaming/mirroring" from an Android tablet?

Thanks. I'll suggest that she gets a Chromecast
