This is a SAMSUNG VG-KBD2000 Smart Wireless Keyboard with Bluetooth Connectivity to Smart TV. The F1-F4 are the Color Keys. We will be prompt in replying.
Easy to set up and seems to be the only device that makes a good Bluetooth link with Samsung smart TVs.
That's great if you surf the internet on the Samsung TV, but not what I bought it for.
I was hoping for a keyboard that would substitute for the tedious business of searching a title using the alpha-numeric grid on the screen for movie services like Netflix and so on.
It does not work on these black and white grids, navigated with the circular directional disc on your remote.
So it doesn't do exactly what I wanted, it's a bit more expensive than ordinary remote keyboards, but it seems to be the only thing that works at all with Samsung TVs.
A decidedly mixed blessing.
