Hi Matt and Guenter,
Thanks for your help in this matter. The EDID spoof using the LG TV EDID worked. The issue I was having was that I had to keep the HDMI source unplugged while I setup the eval board, and plug it into RxA only after the EDID spoof script was run. I also found that either the Advantiv USB or Advantiv Serial connection (to the DB9 RS232 connector) to the board worked just fine.
Best regards,
Kent
