HDTV Setup

If you've got your heart set on a new big-screen for the big game, you're in luck. The days leading up to Super Bowl Sunday are the traditional last, best chance for retailers to dump their remaining inventory before new models hit shelves in the spring. The competition is as fierce among stores this week as it will be on the field this weekend. But your primary TV shouldn't be an impulse purchase, and jumping on the first hyper-bright picture or low pricetag that catches your eye is a recipe for long-term remorse. So, slow down, take a deep breath, and tackle these tips to guard against the dreaded Monday morning quaterbacking.

It’s a given that most readers of Home Theater are that guy—the one friends and family call when they need a new HDTV. But it doesn’t stop there. Because after your 82-year-old grandmother finally tosses out that old Sylvania console and buys a 52-inch LCD on your expert recommendation, you still have to help with the picture settings. We can’t have nana blowing out her sensitive retinas on the factory torch mode, now can we? Oh, what those eyes have seen...

In movies, one size never fits all.

By now, most home theater fans have undoubtedly grown used to seeing letterbox bars on many movies they watch. In today’s high-definition era, any content with an aspect ratio that’s greater than a 16:9 (a.k.a. 1.78:1) HDTV screen must be presented with black bars on the top and bottom of the frame. Blu-ray viewers have many examples of this. Approximately half of all modern theatrical films are photographed in the scope aspect ratio of 2.40:1. Iron Man, Tropic Thunder, and Wall-E fall into that category. Scope photography is sometimes referred to as 2.35:1 for reasons that are too complicated to explain in detail here. Just know that 2.40:1 is technically correct, although many people in the industry continue to use the term 2.35:1 interchangeably. At the other extreme, material narrower than 16:9 (classics like Casablanca and The Adventures of Robin Hood are 1.37:1) will have pillarbox bars on the sides. In the middle, movies composed for 1.85:1 (such as the The Sixth Sense, Hellboy, or Knocked Up) nearly fill an HDTV.

The 2007 HDTVs

This time last year, we tested 61 2006 HDTVs to learn how they process all the detail contained within 1080i, the most common high-definition broadcast format. It's the highest resolution format the majority of HD broadcasters and cable channels use, including CBS, NBC, CW, HBO, and Showtime. The results of our 2006 tests were quite disappointing; less than half of the HDTVs were able to properly process the interlaced broadcast signal to the TV's native, progressive resolution. This year, we have expanded our testing to include 74 HDTVs that range from 19 to 67 inches. We have added a new test for 1080p displays to judge their resolution with motion as compared to their stationary resolution. This test illustrates how all HDTVs lower the amount of detail you can see when the camera is panning or where there is action in a scene, such as on a football field. More on this later.

You've just come home with that new TV. Want to know how to get the best picture you can, in about five minutes? Even if you've never done more with your TV than turn it on before grabbing the popcorn, we can help you get the best picture from your TV using nothing more than a DVD you already own.

Test your own TV like we do it.

To test your display's performance, you'll need not only specialized test generators and measurement devices, but also actual video material. After all, just because a display measures well doesn't mean it's anything you want to look at. For that matter, there are no objective measurements for things like scaling and deinterlacing. For consistency, we try to use the same or similar test DVDs (and now HD DVDs) for our testing in each display review and in our video Face Offs. If you want to see how your TV stacks up—or you wonder what we're talking about every month—here are most of the test discs we use and why we use them.
