Scott Wilkinson ... Can you Tell the Difference?

Scott Wilkinson

Episode 1673

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 Wilkinson and the Super Stream

Episode 1665

Scott Wilkinson joins Leo to talk about the Super Bowl and how he usually just watches the Puppy Bowl on Animal Planet. But this year, he's interested in the game because of the 4K HDR streaming options you can enjoy. Leo says it's through the Roku Ultra and the FoxSports app. It'll also be broadcast in 60p. So 4K 60p and HDR. But it almost didn't happen, as Fox Sports and Roku had to sign a last-minute deal to enable it to happen. But Roku isn't the only option. Amazon Fire enabled sticks and TVs will also be able to do it.

Will my AV receiver handle 4K HDR?

Denon AVR-S940H

Episode 1664

G Scott from S Lake Tahoe, NV

G Scott wants to know if he can stream 4K with Dolby without any special devices. Leo says if you have a 4K streaming box, you can plug them into your AV receiver, and if it has audio return, it should do Dolby. But Leo says he bought an all-new AV system for it. But remember that live broadcast TV won't be shot in 4K; it'll be upscaled to it. Then you'll need a 4K capable smart box. 

Scott Wilkinson ... Skin in the Game

Episode 1663

Scott joins Leo to talk about the Super Bowl. It'll be the first one broadcast in 4K HDR. You'll be able to see it on DISH network and DirecTV, Comcast, Xfinity, and Obtise Optimum. Or you can stream it via the FOX App or FuboTV. Fox says you can stream it on Roku Premiere or above, or the Amazon FireTV 4K. Some 4K Smart TVs and the Xbox will also do it. The AppleTV will also stream in 4K, but not HDR because Fox is using HDR10, which Apple doesn't support. But the problem is, Fox is shooting it in 1080p and upconverting it into 4K.

Is there a good 4K monitor for my computer?

Dell U2718Q

Episode 1647

Mike from San Diego, CA

Mike is looking to upgrade his PC display with a 4K monitor. Is there a monitor out there as good as the 5K iMac? Leo says that you can get a 5K monitor that is comparable. Costco has a 43" Dell 4K monitor. Will it be pixely? Or will it look good? Leo says that Dell makes really nice monitors. But Dell has two lines: an inexpensive line that's less color accurate, and an expensive line that is color calibrated. So it depends on what you want and need. If you're into photography and video, you want a calibrated display that can give you the full-color gamut.

Is there an advantage to using an Apple TV instead of a Mac Mini as a set top box?

Apple TV 4K

Episode 1555

Bruce from Las Vegas, NV

Bruce upgraded to an LG C7 TV, and it's been the best TV he's ever owned. He has an older generation Apple TV, not the new 4K version that's out now. He's wondering if it would be better for him to get a Mac Mini instead. He wants to know what the difference would be between Apple's tvOS and macOS. Leo says the new Apple TVs support UHD and high dynamic range (HDR). One of nice things about using an Apple TV is that it's automatic, Bruce would just have to plug in the HDMI cable and everything would work. The other thing it does is Dolby Atmos sound.

Why is my Blu-ray player "jerky?"

Sony UBP-X700 4K Ultra HD Blu-ray Player

Episode 1549

Rich from Tuscon, AZ

Rich recently bought a 4K TV, now he's having issues watching Blu-ray DVDs that are non 4K, because it's a bit "jerky." Leo says it's called "decoding hesitation." Scott says that the very first Samsung Blu-ray players had problems with resolution and detail. It's also related to upscaling. What's odd is that it's inconsistent, happening every 5-10 seconds. Leo also says the Blu-ray player is losing sync when decoding the data stream. A better player will fix the problem, and if Rich is looking to get the next component in his new 4K system, the Blu-ray player is where to start.

Scott says that there are now 4K HDR projectors, and you can get them under $5,000. It sounds like a lot, but it really isn't considering where the prices were last year. Sony makes one that uses a technique called E-Shift, or 4K enhancement. The pixels 'wiggle' back and forth and can create close to 4K using 1080p imagers. It's pretty impressive. Scott says that the black levels are key to making the image really pop, and JVC is better with black levels than Sony. TheDLA-X790R is the one with great native contrast ratio and deep blacks.
