I can find all the discrete inputs for this model except HDMI 1 and 2. Do they even exist?

Have you searched and found the posts called "SAMSUNG CODES" or this one?

This has been an ongoing topic here.

Groovit, thank you. Yes, I saw the huge Samsung thread that PHSJason posted but to be honest with you, I'm new at this and didn't understand the device codes. I was looking for a model or type (HLN series) but the list was too confusing. I don't know what device code the HLN is.

I just randomly try those codes from Jason till I find the one that hits.

There are only two protocols/device codes/sets to try (NEC2 and NECx2) for any given function number/code.

Search Jasons thread and the one I linked to. I comment several times in each about the nature of the two code sets that Samsung uses under the name tgrugett. An exact duplicate list of functions is given for each set. Find your desired command an try it provided you are using a remote that allows you to import pronto hex.

The codes Jason initially posted were NEC2 versions. He later in the thread supplied the NECx2 versions and so did I in the X-post thread I pointed you to

Ok, I got all the commands for both them. I'll try them out when I get home. Thanks again for your help.
