It’s no secret that when you go to your local big-box retailer to look at HDTVs, the sets on display are brighter than the sun. Manufacturers want the brightest set on the shelf to draw you to their TV. When you get that new set home, you’re not likely to find your picture looking much better.
That’s why it’s so great that calibration DVDs exist, allowing you to properly set your picture settings to get the most out of your TV. There are several different options available when it comes to the DVDs, but two pop into most people’s heads: The Avia Guide to Home Theater, and Digital Video Essentials.
Avia is a great product - and the first calibration disc I owned. When it comes to setting up your HD signal, however, the newly released Digital Video Essentials HD Basics from Joe Kane Productions is your best option. It’s the first product on the general consumer market specifically designed for Blu-ray and HD DVD, allowing you the chance to calibrate your HD signal using HD material. Avia has a HD release listed as “Coming Soon” on its web site.
Having recently received the HD DVD version of DVE, I’m going to take you through the process of calibrating my setup. First a look at what I have in my living room:
50-inch Samsung HLR-5067 720P DLP
Xbox 360 HD DVD player hooked up via component video
Yamaha HTR 5750 5.1 channel receiver
Klipsch 5.1 channel Quintett II speakers
Klipsch KSW10 Subwoofer
My TV was last calibrated roughly two years ago after purchase. I performed that calibration using the original Avia disc. After two years of minor tweaks it was obvious a recalibration was in order. In the spirit of full disclosure, I’ll show you my before and after settings. Note that I’ll be using only the menu options available via the TV’s main menu and not the set’s service menu. Almost all TVs have a service menu accessible only to qualified technicians due to the potential for permanent damage.

The Disc Itself
Since this isn’t a review of DVE, I won’t spend a ton of time on the disc itself. Suffice to say there’s a lot of content, more than 100 individual listings in the disc’s index, with more than half of that dedicated to test material. Along with the test patterns, there are a couple hours of information on how HD signals are created, calibrated and adjusted at the source. You can certainly skip the non-test material and get right to calibrating your set, but the background info is very informative and goes a long way to help you understand why your monitor behaves the way it does. The introduction to HD section was of particular interest to me.
I made several discoveries about my TV while working my way through the video test patterns. First, it doesn’t accurately display below-black color in the PLUGE with Gray Scale pattern, as systems standards say it should. Also, I found that my set will properly calibrate blue and red using the color filters included with the disc, but can’t come close to getting green right. According to the disc, these are common problems. Finally, I determined that my set is likely using the standard definition decoder (ITU 601 SMPTE 170M to be exact) for setting color instead of the HD decoder (ITU 709 SMPTE 296M), another very common issue in some HDTVs.
