Ok, got one of these new bad boys for Christmas to replace my very old ATV. I am experiencing the remote lag which is disappointing. I have googled here and the web and it seems there are a few possible remedies related to BT interference: 1 Move the unit 2 Shut off the mic 3 Change Chroma to 4.2 whatever Chroma is? 4 Shut off HDR 5 Get a new HDMI Apple recommended Belkin cable. I am thinking #5. I just unplugged my old ATV and used the power cord and the HDMI from the old unit. The HDMI was an Apple HDMI bought at the Apple Store when I bought the old ATV. Should I be using the 4K power cord? Everything about the unit works great. The ATV remote app on my phone works perfectly, but that's through wifi I believe. Any tips?
