Televisions

With 120Hz, 240Hz, and even 600Hz, refresh rate gets a lot of attention in the marketing of new HDTVs.

What it is and how it works is interesting, but why it exists is even more so. And it can have a profound effect on the picture quality of your HDTV.

Curious?

There still seems to be some confusion about the difference between 1080i and 1080p. Both are 1,920x1,080-pixel resolution. Both have 2,073,600 pixels. From one perspective, 1080i is actually greater than Blu-ray. And, you can't even get a full 1080p/60 source other than a PC, camcorder, or some still cameras that shoot video.

True, 1080i and 1080p aren't the same thing, but they are the same resolution. Let the argument commence... … Read more

Cleaning a TV screen seems easy. Windex, right? Wrong. Most modern HDTVs have special coatings on their surface that can be ruined by strong cleansers.

But at some point, every HDTV screen needs a good cleaning.

Here's how.… Read more

On one side, there's 4K: four times the resolution of your current TV. LG, Sony, JVC, and others have all announced or shown upcoming 4K displays.

On the other, there's OLED: Organic Light-Emitting Diode. Significantly better picture quality than your current TV, plus lower energy consumption, and even thinner cabinets.

So what's more exciting?… Read more

One of the things I take for granted as a TV reviewer is the translation from model number to things like screen size, model line, display type, and so on.

I've gotten a few e-mails lately from people looking for help trying to decide between similarly priced models, with radically different model numbers. Are they similar? What does the alphanumerical soup mean?

While model numbers change yearly (or sometimes even more often), there are a few guidelines you can use to help you sort out the what from the what.… Read more

In a small room away from the main convention center at the CEDIA Expo, LG showed off its upcoming 84-inch 4K LCD, the LG 84LM9600.

I got a close-up look at the new ultraresolution panel, got a lot of questions answered, and got a rough idea what we can expect when it starts shipping next month.

Curious? I was too.… Read more

Looking to replace an old LCD panel (or even, horrors, a tube) with something new, modern, and feature-packed? Ah, who are we kidding, "feature-packed" is code for "not in my budget."

It might be today. For a limited time, and while supplies last, Amazon has the VIZIO E3D470VX 47-inch LCD HDTV for $598 shipped. When it comes to features, this model's about as packed as they come.

For starters, it's a 3D TV, one that relies on lightweight passive glasses rather than expensive, inconvenient active-shutter glasses. Vizio supplies two pairs, but you can expand … Read more

A week after Sony Chief Executive Kazuo Hirai uncloaked the company's massive 4K 3D TV, Sony has uncloaked its price, too: $25,000.

People can pre-order Sony's 84-inch XBR-84X900 today, but it won't be in stores until November, Sony said today.

The 4K TV has four times the number of pixels -- 3,840x2,160 -- as a regular HD TV. The 4K label, a bit of a loose term meaning 4,000, refers to number of pixels across the width. Sony is pushing hard to move the industry to 4K video, hoping for a new upgrade … Read more

Most "smart home" automation systems require a significant investment in additional equipment in order to smarten up your otherwise not-so-smart gear.

Sony and Control4 want to simplify the buying process, and bring home automation to a much wider audience, by integrating a full Control4 "brain" into Sony's new ES line of receivers. … Read more
