That URCs would have to be tested and what commands you find missing would have to be filled in. No one I know seems to document this in depth so just like you heading into a new wilderness you get to prepare as best you can and learn as you go.
I have 5 Samsung TV's bought August 2012. Typical model number UN60ES6100F. They are connected to home entertainment system controlled by URC Universal remotes that have the Samsung commands programmed in. If I upgrade to new Samsung QLED models would they be compatible with the existing remotes as programmed? Or would I have to reprogram the URC? (assuming I would not be taking advantage of any new commands that did not exist in 2012...)
