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

Japan Display revealed yesterday that the mega joint venture -- consisting of Sony, Toshiba, and Hitachi's manufacturing prowess -- started mass production of a 5-inch 1,080-pixel LCD screen bound for future smartphones. … Read more

Shopping for a new television can be an overwhelming experience. Confusion plagues even the most careful shoppers, and TV manufacturers, retailers, salespeople and numerous Internet sources can create more uncertainty as they push extra features, new technologies, and add-ons in the incessant pursuit of profit.

I hope that this guide, which I created in 2002 and have updated every year since, will help you cut through the confusion with unbiased information so that you can select a new television. It won't answer every question, and when you read it, it won't tell you "the perfect TV for … 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

Apple's iPhone 5 beat Samsung's Galaxy S3 in a display tech "shoot-out" at screen testing firm DisplayMate Technologies.

The iPhone 5's Retina screen is the best smartphone display that DisplayMate has tested to date, according to results the firm posted today.

iPhone 5: "It is a significant improvement over the display in the iPhone 4," said DisplayMate's Raymond Soneira, who cited much lower screen reflections, much higher image contrast and screen readability in high ambient lighting -- the latter, the highest he's ever tested.

DisplayMate -- which gave the display an "A" -- also cited improved color gamut and factory calibration that "delivers very accurate colors and very good picture quality." The Retina iPad is the only thing that beats it in accuracy, according to Soneira.

Galaxy S3: While DisplayMate said the OLED display is "very good" and gave it a "B+," it fell short of the iPhone 5.

The problem, comparatively, as Soneira sees it, is that the Galaxy S III's OLED technology is still on steep development curve. OLED is "a new technology that has not yet been refined to the same degree as LCDs, particularly the IPS LCDs on the iPhones, so it doesn't objectively test or perform as well as the iPhone 5," according to Soneira.

The brightness on the Galaxy S3's display is about half of the iPhone 5 "due to power constraints resulting from the lower OLED power efficiency," among other issues, that makes for poorer image contrast and screen readability in high ambient lighting compared to the iPhone 5, said Soneira.

Other issues he cited are a "lopsided" color gamut and calibration. "For some reason Samsung has not bothered to calibrate the Color Gamut on any of its OLED displays, so they are wildly inaccurate and produce inaccurate and over saturated colors." … 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
