I have a 65HU8590 and wanted to have for this a suitable keyboard. I had a Logitech keyboard K400r home and have this test as connected from my HTPC to the TV. You work properly, however, combines the TV off after every time new with the result that I get a message after each power "device disconnected" followed by the message "Device connected" what I have to confirm OK. That was me a bit annoying in the long run and therefore I have but then resorted to KBD2000 although I was not really willing to spend so much for ne keyboard.
The keyboard itself, I can only say positive. It affects quality workmanship (much higher quality than the Logitech) and everything works fine. The only thing I miss is a keyboard light. For a PC the keyboard is usually right in front of the monitor, its light anstrahl the keys beautifully. Before nem TV you sit but most further away and here you have in nem dark room but had problems while typing. Especially at the price it would be appropriate.
