Larry bought a used TV and the audio doesn't work on one channel, except for commercials! Leo says that could be due to secondary audio programming (SAP). The channel may not support that. He should try turning that off. He should try using some headphones and see if they work. If he can hear the channel, it's clearly something wrong with the audio processing on the TV, or with the speaker setup. He should set up mono sound and see if that works.
Ben wants to know why he's having trouble connecting his TV with Cat 5 ethernet. Leo says to try a shorter cable. It may be a kink or a spool is causing connection issues.
Michael is looking to get a TV and wants to know if he should get 1080p or 4K. Leo says he should definitely get 4K moving forward. But even more importantly, he should get a TV with HDR. It has a much nicer look. Leo's choice is the LG B6 OLED. It comes down to budget though. Michael wants a TV that has no bezels. He wants to hang it on the wall like a painting preferrably an 80" model. Leo says that Vizio has a nice one.
Don wants to get a TV for the outdoors, but they seem to be four times as much. Leo says that's because TVs are designed for the darkness of a living room or home theater. So getting an outdoor centric TV requires better capability to see in bright, ambient light. There's also weatherproofing issues. Don should check out OuterAudio.com. They recommend the high end SunBright TV for outdoor TVs. Sunlight can also damage TVs.
Tim has an iPhone 6S and when hooking it up to his smart TV, nothing happens. The TV says it has the signal, but nothing happens. It has worked in the past. Leo says that it sounds like HDCP may be the issue. That's digital copy protection. Everything in the chain has to be HDCP compliant to work. But that should only be an issue if he's watching YouTube or a movie. It should work with photos and home videos no problem. Tim says a friend's iPhone works though. Leo says it sounds like an iOS issue, then.
Scott joins Leo to help Doug from Albuquerque, NM figure out what TV to buy. Scott says that the "spousal acceptance factor" is high on big flat screens, but not on speakers all over the house. So for Doug, a soundbar is probably best. As for the TV, Doug's living room is in a bright area, with plenty of windows, so Scott says an LED LCD TV is going to be the best option.
Tom is buying a new TV today and wants to know what to get. Leo says it depends on his budget. If he's spending a few thousand, then OLED is the way to go. Better yet, he should get a larger size than he would think. If he's at less than a 10' viewing distance, 55" is OK, but Leo likes 70". HDR makes a significant difference if he likes to watch movies. 4K, for sure. But everything else in the chain has to be 4K HDR in order to get the benefit.
Andrew wants to be able to control several monitors separately by remote, but with regular IR remotes, everything he does will affect all of the TVs. Leo says ideally he'd like to be able to do this in software without the remote. Leo says it would be nice if those monitors had a serial port for control. There are remote apps that use Wi-Fi with a phone. Openhab has some documentation for controlling TVs using a serial protocol.
Rick wants to know how he can bring his Amazon Fire Stick with him when he travels and plug it into the TV where he stays. Leo says that older TVs will require an HDMI to Composite converter, but newer TVs have HDMI ports. So he could just plug them in. Many hotel Wi-Fi hotspots require captive portal registration to use it, and the signal really isn't that good. Also some older TVs may not be HDCP compliant.
