When building (or adapting) a home theater for high-definition viewing, it’s best to start with the basics. In this case, the TV is the first thing that needs to be taken care of and, to be blunt, the bigger the screen the better. And while you may prefer plasma over rear-projection, or an LCD panel over a front projector, it’s the resolution that plays the most important part because it’s “locked” in and can’t be changed for the life of the set. Right now 1080p is the poster child, but even 720p resolution will provide a much better picture than the standard TV sets we used to put up with.

HD Cable Options: Component and HDMI
When connecting HD devices to the display, your choices are either component cables (for up to 1080i) or HDMI cables (for up to 1080p). HDMI has an advantage because it’s a single cable that also transmits audio.

But HDMI can still fail to function correctly, especially if you go with a cheap cable. “Keep in mind that as great as digital is, there can still be problems—a skinny little wire can have signal issues,” says David Wiswell, group manager for

product development and engineering at Panasonic Projector Systems Company. “Using digital cabling is great, especially as HDMI makes it easy for those with limited experience in wiring their TVs,” he says. “Just be aware that digital doesn’t ‘gracefully fail,’ it’s more like ‘falling off a cliff’ where it locks up because the signal has dropped under the marginal edge.”

With most displays now including HDMI, it’s hard to find a compelling reason not to use it. But this gives way to an input issue because many TVs only have one or two HDMI inputs. Short of pulling/inserting plugs every time you want to switch between your HD cable box or HD player or some other device, the solution is an HDMI switcher that accepts multiple HDMI inputs and then sends the signal out to the display. But switching requires punching the correct button on the switcher or the remote every time you want to change sources, so something along the lines of Iogear’s HDMI 2 x 1 Automatic Switch might be better, as it senses and automatically switches to whichever of its two inputs are active.

Tips for Surviving the HD DVD vs Blu-ray Battle
Until recently, the only way you could watch high-definition programming was to get it from a cable box, satellite receiver or an over-the-air HD antenna. Mark Jackson, president of EchoStar Technologies (parent company of satellite provider Dish Network), says high-definition bandwidth limitations presented an initial challenge for all content providers, but MPEG-4 compression, new modulation methods, and advanced hardware helped overcome these restrictions. Now, content providers can offer more high-definition programming, which helps justify a consumer’s investment in HD equipment.

Consumer justification gets an added boost via the “stored HD” on two competing high-definition disc formats: HD DVD and Blu-ray. The differences between HD DVD and Blu-ray have already been covered ad nauseam, so unless you’re going to wait it out, you’ll have to choose between getting an HD DVD or a Blu-ray player (or a Playstation 3 if you want to combine gaming with Blu-ray viewing). Or, you could splurge and get a player for each format, though that’s a costly proposition (as an alternate, LG’s Super Multi Blue Player handles both type of discs—even if its HD DVD access is a bit spotty—and recently Samsung announced a dual player coming later this year).

Those who say there’s really no difference between DVD and...
