An extended warranty on a TV appears, at first, like a decent idea. After all, TVs are expensive, very high-tech, and pretty complex, right?

However, dig a little deeper and you'll find that extended warranties are almost always a waste of money.… Read more

If you read my "What is refresh rate?" post, you'll know that plasma TV manufacturers (Panasonic, Samsung, and LG) make a point in claiming a "600Hz" refresh rate on their TVs. As we discussed in that article, it's not exactly comparable to LCD's 120 and 240Hz refresh.

So what is 600Hz, and how does it work?… Read more

The Consumer Electronics Association has decided on a name for 4K resolution: Ultra HD. I guess this leaves room for future resolution increases, with names like Uber Ultra HD (UUHD), Super Ultra Definition (SUD), and, of course, Fantastic Ultra Brilliant Amazing Resolution (FUBAR).

But 4K is still largely just an increase in resolution, which is only one aspect of picture quality, and not the most important.

Here are three things more important than an increase in resolution.… Read more

Even after two articles, and a tremendous number of page hits, there still seems to be lots of questions about HDMI cables. I credit this to the complexity of the topic and the mountain of misinformation out there, rather than any particular failing of the writing on my part. Judge as you see fit.

But the fact is, a recent reposting of my original article lit off a bevy of new questions. Instead of expanding on that already bloated article, I figured a new one would be a better idea.

On to 3D, 1.3/1.4, getting physical, and more...… Read more

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

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
