I take it this is a continuation of our prior discussions.
Let me be clear here. The MENU or GUI SYSTEM is incomplete and I don't make any assertion that the RS232 system would enable anything in the menus. It's well known that these digital display models never put everything in the menus so we are left to chat with the TV over RS232 to setup what's not in the menus.
Again, I do not expect the menus to become enabled.
I got LG LV761H and some features are grayed out. Someone in this forum told me that If I want to turn on that feature I need to connect it through the R323. But the question is how?
I would help a lot if there are videos related to this problems.
