HDTVs, projectors, and surround sound systems.
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.
Scott says that when calibrating a TV, different people see colors differently. It's called Metaphorism. It kinda makes it a challenge to have accurate color reproduction.
Technology always marches on and your technology going out of date is happening faster and faster. So Scott says don't get caught up in it. Buy in when you need to and enjoy your technology as long as you need to.
Eddie bought a new 65" Vizio 4K TV. What sound bar should he get? Leo says that a sound bar is made for convenience first and audio quality second. Eddie will want to get a sound bar that comes with a subwoofer, though. A home theater system is the ideal solution, but if his space limited, a sound bar is a good compromise.
Jeff has a Vizio 4K TV with a Bose surround system. He cut the cable recently, but now he doesn't know how to use his surround sound system with the TV because it doesn't have audio out. Leo says most systems now connect audio via a SPDIF or TOSLINK optical connection. The Bose should have an optical connection to it. He'll also need a TOSLINK cable. There's different connectors, so he'll have to see what his Bose wants, and what his TV takes. Monoprice makes them for pretty cheap, and Amazon Basics does as well.
Scott Wilkinson says he went and saw FIRST MAN in IMAX because the moon walking scenes were shot primarily with IMAX cameras to get a larger, taller image. Scott says that is the trend now, shooting a portion of a film with IMAX in order to make those scenes far more immersive and dramatic. Scott says that there's now a program called IMAX Enhanced, which brings that experience into the home by filling the 16x9 screens of today's TVs with additional content. No letterboxes.
Both of Seth's parents are now hard of hearing and they need headphones to watch TV. Is there a system that can do it for them? Leo says that hearing aids now can pair to the TV. So if they need a hearing aid, that's a good feature to get. But if he wants headphones, Leo got his mother a pair of Sennheiser wireless RF headphones. They work much better than Bluetooth.
Jerry has a Dish DVR which can receive over the air signals. He saves the channels and gets no information on programming. Leo says that's because the DVR isn't getting a channel guide in the over the air signal. Channels used to include that data on side ban channels, but they may have stopped doing that and as a result, his DVR can't get the channel guide data. That's why TIVO charges a monthly fee, for a channel guide.
John bought a Samsung QLED 4K TV. Does he really need to get a Blu-ray player for it? All he really watches is Netflix and it's pretty good. Leo says that streaming gets compressed, so even though it looks pretty good, Blu-ray is uncompressed and will look far better. The way he can tell is by looking for "macro blocking." He'll see it in solid blacks, and it'll show bands, instead of a smooth gradient. He'll also see some jaggies in titles and text. But Leo says in spite of that, Netflix does a good job. It just depends on if he wants the perfect image or not.
