I don't know if anyone has posted this yet, but if you are trying for discrete HDMI with the HLP6163, you have to update the firmware. The set originally shipped with the ATL-1024 board and must be updated to the 1029. This requires changing out the digital controller board (there is no way to flash the bios or update through the service port). I called Samsung and they sent out a tech to do it at no charge. Now the discrete HDMI code works as 8B.
