This week, Scott says that Tom Cruise came out this week against "motion smoothing" in modern TVs and encourages fans to turn off frame interpolation on their TVs before watching Mission Impossible: Fallout on Blu-ray. Scott says it isn't trivial to find the feature and turn it off either. It's called something different with every manufacturer. On top of that, it's turned on by default. Motion smoothing, Vivid mode, or frame interpolation, sharpens your image, which can be helpful in watching sports or action movies. But filmmakers hate it because it changes the look of their films.
Bernie wants to know if HDMI is the same as optical for audio quality. Leo says that both connections are digital, so it's the same quality. Optical will give him Atmos and other multi channel stereo options as well.
Eileen bought a Bose sound system, which is connected to an optical splitter, so they can use her headphones too. But now the headphones won't work after a power surge. Leo says it's possible that the power surge fried the optical splitter. She should check if the headphones work with her TV (she may need to change her audio settings in the TV). It may also be possible that the settings changed in her TV, so she should look in there and see what it's offering. She may need to reset it to PCM unencoded audio or something similar. She should just try different settings.
Scott got an email from a listener who wanted to stream using an old analog receiver and speakers, and Synology NAS. Scott says that the listener discovered that using the Chromecast audio (which has an analog/digital output) was the ideal solution. It works great with a powered speaker or a pair of speakers which are powered by the AV receiver. You have to set it on AUX, but if all you have is analog, this is a great workaround.
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.
