OLED: What we know

Rumors are still flying about the next great TV technology: organic light-emitting diode.

It's difficult to pry info out of the companies involved, but I figured it was worth putting down what we know, what we think we know, and what we know we don't know, ya know?

OK, go.… Read more

Home networking explained, Part 2: Optimizing your Wi-Fi network

Editors' note: This post is part of an ongoing series. For the other parts, check out the related stories.

Since my last post on the basics of home networking, which is Part 1 of this series, I've been flooded with even more e-mails than I had been before (which explains why some of you haven't heard back from me). The good news is that nobody is asking about what a router is anymore. I guess I did an OK job explaining that in my previous post.

Most of the e-mails this time asked about how to have the … Read more

Apple TV vs. Roku: Which streaming box should you buy?

Every time there's a significant update to either product, the e-mails start filling up my inbox: so now which is better, the Apple TV or Roku?

It's an understandable question, and one that only gets harder to answer now that Apple TV has recently added two, significant features: AirPlay Mirroring via Mountain Lion and a dedicated Hulu Plus app. While it used to be easy to give the Roku LT the edge for costing half as much and offering more streaming services, it's a much closer call with the Apple TV's standout features.

Let's take a look at the strengths and weaknesses of both boxes.… Read more

Are letterboxed movies really 1080p?

CNET reader Doug asks:

Hello! I was watching a movie on Blu-ray the other day filmed in the 21:9 aspect ratio and I realized that it technically wasn't "1080p" since about 1/4 of the screen was taken up by the horizontal black bars (called "letter boxing," correct?). Anyway, I was just wondering how many pixels were being used on the TV. Thank you!

Ah, letterboxing, how I love you.

To understand letterboxing, we have to talk about aspect ratio. HDTVs are 16x9, or 1.78:1. Slightly wider than they are tall, they're pleasantly rectangular. Old-fashioned tube TVs were 4x3, or 1.33:1, so closer to square. … Read more

'Jaws' looks killer on Blu-ray

A lot of people have noted that best thing about Blu-ray is seeing "new" versions of old films in the format.

"Jaws" doesn't qualify as a really old film, but it did first hit theaters in 1975, so it's certainly an older film, and it looks truly impressive on Blu-ray. This is one of the films that Universal has chosen to restore for its 100 anniversary (of Universal, not the film), and some of its earlier restoration efforts have been lauded while others have been criticized for introducing too much digital noise reduction and … Read more

PS3 gets new YouTube app, controllable via smartphones

The PS3 has a solid collection of streaming-video apps, but the lack of a dedicated YouTube app has always been a conspicuous omission.

That ends today, with Sony and Google rolling out a new YouTube app for the PlayStation 3. The new app features a big-screen-friendly layout with controls optimized for the PS3's controller. You'll be able to log in to your YouTube account, giving you access to your subscribed channels and other YouTube community features.

There's also an option to use your smartphone as as a controller for the app, letting you take a video you'… Read more

Why 4K TVs are stupid (still)

Editors' Note: An updated article entitled Why Ultra HD 4K TVs are still stupid was published on January 28, 2013.

A few months ago, hot on the multitude of 4K TV announcements at CES, I wrote an article called "Why 4K TVs are stupid."

I was shocked, shocked to find so many angry, contrary opinions on the subject. I mean, this is the Internet. Surely everyone is cordial and like-minded.

The comment section was the usual bog of ad hominem, straw man, and plain nonsense arguments. But buried deep within the chaff were a few good questions worthy of rebuttal. So if you'll indulge...… Read more

iTunes vs. Amazon: What's the best video service on the iPad?

The future of TV, movies, and home entertainment feels like it's changing by the day, thanks to the impact of the digital revolution. Netflix is the top dog thanks to its $8 subscription streaming service, but your viewing choices are severely limited. For a la carte, pay-as-you-go services, Apple's iTunes has been the default choice for many when it comes to buying, renting, and viewing videos. Splitting the difference was Amazon's Instant Video: it offers a diverse library of pay-per-view TV shows and movies, plus a subset of "free" content for subscribers to the company'… Read more

Roku names first Streaming Stick partners, keeps mum on exact price and release date

Back at the January Consumer Electronics Show, Roku showed off a prototype of its Streaming Stick -- a version of its streaming box miniaturized to the size of a USB drive, and designed to work with any TV equipped with an MHL (Mobile High-Definition Link) port. We thought it was cool enough to bestow it with a nomination as one of the best home theater products of the show.

The good news is that the Streaming Stick is on track for its promised 2012 release. Roku today affirmed that the product will be released "in the coming weeks." … Read more

Nexus Q launch delayed, preorderers getting free device

Google's Nexus Q played a big role in the company's Google I/O keynote, but it looks like the company is going back to the drawing board.

In an e-mail sent to anyone who preordered the device, Google explains that because of "initial feedback from users," the official launch of the Nexus Q is being postponed indefinitely, so it can "do even more than it does today." Additionally, Google is offering the people who preordered a free Nexus Q as a reward for their early support.

While it's surprising to see Google change … Read more
