This guest technical primer was submitted by Dave Rodgers, marketing manager for Elite Screens Inc. and a 20-year professional in the audio/video and wireless communications industries.

You might be surprised to learn that there is more to contrast than just black and white. The intensity of color matters just as much. While the topic of black-white level has been explained in all its glorious intricacy by the best minds in the AV world, I prefer a more basic approach — one that makes sense to someone who doesn’t know lux from lumens.

We tend to forget that not all readers have been around the block when it comes to the language of video. Those that have know the tricks of the trade, and what all of the terminology means. True, even they’re sometimes mistaken, and we ourselves can get caught out from time to time with what’s being offered this year (or this week!) in the ever changing high definition (HD) and ultra high definition (UHD) world.

But manufacturers seldom offer much help in this, or even do their best to obfuscate. In their specs, descriptions, and promotional copy, one thing you won’t find clearly stated is what their products won’t do...

TV shopping has become vastly more complicated over the past decade. Buyer confusion used to revolve around issues of 720p versus 1080p, LCD versus plasma, edge-lit versus full-array, 3D or not 3D, and “What’s a smart TV?” All manageable problems, in retrospect.

Are curved screens going to take over the world? If you walk into one of the 500 Best Buy stores featuring Samsung’s impressive Entertainment Experience display area, you might think so at first glance. Stylish curved-screen TVs are front and center in the ultramodern space, displayed under glowing “Curved UHDTV” signs that beckon you to come over and take a closer look.

What makes a good TV picture? Sharp detail? That’s a factor, sure. Vibrant color? Of course. What about brightness? Definitely, you don’t want a dim picture. How about black level? That’s vital. After all, you don’t want grayish blacks; that wouldn’t be lifelike.

There’s no doubt that Smart TVs have been getting smarter. While the earliest Smart TVs were limited to streaming movies and basic Web browsing, today’s models may encompass voice or gesture commands, the ability to “throw” your favorite photos to the screen from your smartphone, facial recognition for customized user menus, or even the ability to recommend shows based on your past viewing.

After years of speculation and skepticism, drooling and disappointment, longing, frustration, and pensive excitement, Organic Light-Emitting Diode televisions are finally available. OLED (oh-lead, if you like), is the first true next-generation HDTV technology since LCDs emerged from their nascent toy stage and started stomping all over plasma TVs.

A customer walks into a showroom and the TV says, “Hey, big spender, come spend a little time with me.”

The customer replies, “Of all the TVs on the wall, why should I spend any time with you?”

Starting with the September issue (and now, online), we're adding a new measurement to our objective TV/projector tests. It's called "input lag" and while it's not as important as contrast ratio or color accuracy (which we already test for), it's an important metric for gamers, and anyone who notices issues with "lip sync."

So here's what it is, how we test for it, and what, if anything, you can do about it.

When the technical specifications of a new but humdrum TV fail to come up to snuff, the model almost certainly will be priced less than the one with better resolution, faster processing, more connections, and so on. Whether it’s manufacturer or retailer, nobody interested in making a buck will promote the TV as “nothing special”—even if that’s exactly what it is. Sellers will likely spin the spec as “great value.” But not always.

I occasionally peruse Internet A/V forums to see what the techier web denizens have to say about the latest news and reviews.

One thing I've noticed a lot of lately, especially after our big projector 3fer, is a fixation on black level, with no mention or thought about contrast ratio.

This is a big deal, as black level without contrast ratio can result in some pretty terrible picture quality.

“What’s in a name? That which we call a rose. By any other name would smell as sweet.”

Quick! Name the play! It’s Romeo and Juliet, of course. And it’s certainly one of Bill Shakespeare’s best lines, particularly in the way it encapsulates Juliet’s whole Montague/Capulet dilemma.

Did you read that headline in Seinfeld's voice? While contrast ratio, black level, and light output all rightly occupy the top of the list of specs one considers when purchasing a new display, color is often completely overlooked.

Good color reproduction usually won't make or break a display, but it can make one that's good into one that's great.

Yet for all its importance, it's rarely understood - and it's regularly done wrong.
