Is my UHD TV HDR compatible?

Episode 1326

Trevor from Hawthorne, CA

Trevor bought a Vizio TV, but it doesn't have a tuner for over the air reception. Leo says that most of the time people don't need tuners because they have cable or satellite. Trevor returned it and went with a Samsung. Leo says the Samsung is just as good. If he's going for over the air content, he could get a Channel Master DVR which works as both. Is it HDR? Leo says it may be. SUHD is HDR compatible, though it came out before the UltraHD premium spec was formalized.

Scott joins us to talk about streaming in 4K and how it isn't really 4K quality. You would need a 4K TV, but it barely reaches Blu-ray quality. So you end up spending extra money for the same quality you have from your Blu-ray player. Samsung, though, has a new line of 4K TVs that offer high dynamic range (HDR) quality. The problem is, there are five different standards for 4K HDR, including a standard by SMPTE and 4 proprietary standards like Dolby Vision. So Scott says it's still not time to buy 4K. But soon you won't have much of a choice.

Should I wait to buy a 4K TV?

Sony

Episode 1152

Marty from Simi Valley, CA

Marty was going out to buy a Sony X900 UHD TV, but then he heard Leo's CES report and decided to wait. Leo says that the X900 is a gorgeous TV, however, waiting may be a good idea because the standards have been finalized and any older TV won't conform to them. Marty says that Sony and Samsung are "guaranteeing" that they will work under the standard. Leo says they'll work, but will it work as well as one that's up to the new standard? That's the real question. It's a matter of how well it works, not if it works.

CES Is Over, and Here's What We Saw

UHD TV at CES 2015

Episode 1152

The big story at CES 2015 was in drones, virtual reality headsets, and 4K TVs. The big news with the 4K TVs is that we may finally have a standard for the ultra high definition sets, as a UHD alliance has been formed and UHD Blu-ray players finally had a standard adopted. But they won't be available until the fall. The standard defines the dynamic range and color gamut, as well as the compression algorithm, which is HEVC/H.265.

Scott Wilkinson and the UHD Color Gamut

Episode 1105

This week on Home Theater Geeks, Scott had Joe Kane as his guest to talk about hi definition color space in television. Leo says that it's a good show to watch because the next generation TVs will not only have higher resolution and frame rates, but also color space that goes beyond the limits of the human eye. Scott says that current TVs don't reproduce red very well. It tends to look more orange. But the new Ultra HD TVs will. Sadly, the content will have to catch up and expand their range of colors to take advantage of that color gamut.

Program note - Scott will be filling in for Leo during 4th of July weekend. Also, Home Theater Geeks is now live on Thursdays around noon. Guests lately include SMPTE engineers who are establishing the television standards for ultra high definition. We've had HD for over ten years now and the industry is moving into 4K in order to sell more TVs. They tried 3D and it didn't really go over too well. There is a new 3D technology called UltraD that's coming this year, but everything is in 3D. And it's not going to do much better. So now it's all about 4K. Leo wonders about high frame rate.
