Charles wants to know the difference between QLED and OLED. Is QLED better? Leo says that it's more marketing. Samsung wants people to think that QLED is as good as OLED, but it's really just another LED technology with backlit LCDs. OLED is a better technology with bolder, more accurate colors and deeper, richer blacks. Is there a risk of burn-in? Leo says that modern OLEDs have solved that problem.
Scott says that TV makers are leading the way to 8K TVs now. But the question is, can the human eye even see the difference between 4K and 8K? Scott says probably not. In fact, Warner Brothers tested 130 people and found that most people either couldn't tell the difference or found 8K TVs only slightly better. And some judged 4K better than 8K. But that could actually be a blind guess. People with 2010 vision sitting 5' from the screen could see the difference, but only slightly. So Scott says we've reached the limit of how the human eye can see the resolution.
Scott joins Leo to talk about home theater and how well Tuba Christmas went. Scott says they had an audience of over 1,000 this year, and it was a marvelous yuletide celebration. There was even one group that tailgated in the parking lot before the concert.
Greg was looking to upgrade to a new 4K TV, and got a Sony Bravia, and found the upscaling was terrible when watching live TV. A year later, the TV has gone out and he has to replace it. Will he have an issue with another 4K TV? Or should he just try and get and older 1080p TV. Rich is not a fan of upscaling, and the native resolution will always be better because upscaling can't invent resolution that's got clarity. Just watch it the way it is, unless it's a 4K native signal. Netflix and Amazon Prime, for instance, stream in 4K. But TV channels vary from 720-1080i-1080p.
Jeff has a 10-year-old HD TV and he's thinking of upgrading to 4K. A TCL 65" with Roku built in. A good buy? Leo says he'll likely need a decoder box to work with the cable subscription. But will he get 4K? Well, that depends on his cable. And even then, no live channels really broadcast in 4K anyway. He can stream it through Netflix and others, but it requires a faster internet connection. One thing he can do is get a 4K Bluray player.
This week was the annual Consumer Electronics Show (CES) and there was a lot of 8K TVs being showed off. Samsung also showed off a new microLED 75" TV. The price is $50,000! Short throw Projector TVs were also popular at CES. LG's Optima is under $2,000.
There were also self driving cars using artificial intelligence and LIDAR. There was also an electric helicopter and self-driving flying cars. There were also Amazon Dash Buttons, which are designed to instantly order a product at the touch of a button.
Marcello wants to get a new 4K TV to go with his new home. Should he wait for HDMI 2.1? Leo says the only real reason to wait for HDMI 2.1 is to buy an 8K TV, which isn't really practical right now because they're too expensive and there's no content for them. It's still a few years away. The more important feature is HDR. So there's no real reason to wait. If money is no object for Marcello, then the LG C8 OLED is the best TV ever. But it's $8,000 for a 70". If he can afford it, it's gorgeous display.
Black Friday Deals are looking very good this year:
Clarence needs to get a new 55" TV. What does Leo know about HiSense? Leo says that HiSense is a budget TV manufacturer from China, but the TVs are really well made. They're the next Samsung. Vizio is another really good TV. In fact, it's the best 2nd tier TV for the money.
What is the difference between OLED and QLED? Scott says that OLED is Organic Light Emitting Diodes, and is based on organic chemistry, or carbon. That's how it makes light. QLED, on the other hand, stands for Quantum Dot Light Emitting Diode, and it's just a higher end LCD TV. The light source behind the panel is using quantum dots, including LEDs to illuminate the image. They are completely different technologies. But the "QLED" term confuses people, and they may think they're getting a special OLED screen, but they aren't.
