A:Answer Since the Bluetooth dongle that you intend to use with the LG - 49" Class (48.7" Diag.) - LED - 2160p - Smart - 4K Ultra HD TV - Black, Model # 49UH6100 is not an LG product, you would need to contact its manufacture to inquire about if it can be used on a TV that does not support Bluetooth or refer to its owner's manual...^IFV
