Is anyone using Harmony remotes with the NVIDIA Shield?
I would like map buttons like menu and channel +- but I can't get them assigned to anything usable even in Harmony Software.

Yes, if you search the term "Harmony" in this thread, you will see we have posted detailed information several times already.
In short, after you read previous posts, get a Flirc. My earlier post mentions my setup to get all working, I just got Flircs, far superior to what I had.

Thanks i will look into that though I thought a harmony remote was sufficient. I have just started playing with the shield so have 3 questions:

1. Why is it each time I enter my library it reloads my posters etc. It's only on the shield not on my other boxes?
2. Anyone knows how to enable rgb 4:4:4 and black levels 0-255. I get a very gray and colorless picture compared to my other kodi clients. My Samsung TV is HDMI low set.
3. How it is with live TV and advanced de interlacing?

It's highly unlikely your TV actually supports FULL RGB. List the model number and we can find out.
