I have been reading and this Logitech K400 Wireless Keyboard with Built-in Multi-touch Touchpad may be the thing to try. But has anyone tried it yet on the LG LN5700 series of smart tvs???
What is a good, inexpensive wireless mouse and keyboard which would be compatible with the LG LN5700 series of smart tv's? The standard remote is very painful when using the "smart" portion such as internet browsing, netflix searching, etc.
