HDTVs, projectors, and surround sound systems.
Bill has a Sony smart TV, and it has to be rebooted pretty often due to the computer crashing. Leo says this is why the industry doens't need a computer put in everything. A TV shouldn't need to be rebooted, so that points to something being wrong with the TV. Sony may have a reboot procedure that can wipe it and reinstall the OS. Since it runs AndroidTV, there should be a way to do it, but how is the question. And only Sony can tell you that.
Neil bought a Harmony Hub for his home theater. He streams with AppleTV and a FireTV stick and he's having trouble having it run Netflix through it. Leo says to make sure the Hub is set to input4, the TV is set to input 1 and then pair the Harmony app with AppleTV. It could be a limitation of AppleTV that the Harmony can't hook into the audio interface. The only device that allows you to launch channels through the Harmony Hub is Roku.
Scott says that the new HDMI standard will be pushing 4K and 8K video at over 5400 gbps. Will HDMI ever be replaced? Scott says that if meta data doesn't survive going through an AV receiver, it could greatly affect the HDR10 dynamic range going to the TV. Your AVR needs to support HDMI 2.0a to do that, and few manufacturers will tell you that. Dolby has launched a program to educate people on which devices will support Dolby Vision.
Cynthia wants to control her Amazon Fire Stick with Amazon Alexa, but she can't. Shouldn't it work together? Leo says not necessarily. At least not yet. Alexa is getting smarter all the time, though.
Cynthia can talk to the Fire remote, so she doesn't really need the Echo for that. Since she paid over $180 for it, Leo recommends returning it and get the $50 Echo Dot instead.
Matt wants to know why an LCD computer display is so expensive vs. a regular HDTV. Leo says that displays are designed to be on 24/7, they're brighter, and have a broader viewing angle. The quality is likely higher with a higher resolution. They can also have CPUs. There's often a longer warranty on them, and the market supports a higher price for a special use item.
Lorne uses headphones with his DirecTV set top box, but when he's streaming Netflix or Amazon content from his TV, he can't hear it through the headphones. Leo says he'll need to use the ARC (audio return channel) to the set top box. There should be a label on one of the TV's ports for that. That will send audio from the TV back into the set top box.
Scott is going to the Grammys this weekend and he says the best part of the awards show is all the live performances. He also says that it's the Super Bowl of music and it's a great time to think about upgrading your home theater system. Leo has an AV receiver with Dolby 5.1. He's perfectly happy with the surround, center channel, two channel speakers, and a subwoofer. But you don't want to next to the surround speakers because you'll hear that more than the center channel dialogue.
Dave has a TiVo and his one gripe with it is how it handles search; the search screen doesn't disappear. Leo thinks it's a bug that has to be addressed by TiVo. Software is hard and bugs happen. TiVo is aware of it as a known issue, so it's only a matter of time until they fix it. TiVo has been sold recently to Rovi and Leo is concerned with what the future holds.
