I walked into an Apple Store and asked, “What monitor/TV should I buy such that my AppleTV remote can control the volume and be the only remote I need?” The geniuses shrugged. I asked, “What brand are these displays in the store that are connected to the demonstration AppleTVs?” They shrugged. We turned them around so I could see the backs of the monitors and I wrote down the model numbers.

It is far from obvious to me.
