Many forget all that along with Bluetooth keyboards and try out the Logitech K400 Plus.
It's wireless as well. If you want to try other Bluetooth keyboards, be sure of return policies.
I recently bought the Samsung ua55mu8000 4K UHD curved smart TV. I was looking for a wireless keyboard and sorted the 2.4GHz logitech K400 plus. But came to know that this TV doesn't support the 2.4GHz RF wireless keyboards but only support Bluetooth wireless keyboard. I called the Samsung customer care and they suggested Samsung Keyboard VG-KBD1000. But I do not find it anywhere in Sydney!
Can any one here has experience with this TV and suggest an alternative compatible keyboard ?
