How do I connect a Chromecast usb to the TV. I have gotten as far as plugging the Chromcast into the HDMI port. It recognizes the plug. In I had to set the TV to the bluetooth setting on the TV. My problem is that my laptop computer or doesnt reconize the device(TV). I have wireless with my computer. My ipad does connect to the TV with Bluetooth but, I can't get any further.
