LATEST ADDITIONS

Ten years ago, virtually all displays on the market were CRTs, but they've gone the way of the dinosaur, replaced with digital technology—LCD, plasma, DLP, and LCoS. The resolutions of these displays are all over the map, from as low as 480p (remember those EDTV plasmas?) to as high as 1080p. In order to produce a picture, a display must convert the incoming signal to its native resolution, which requires some type of video processing and scaling.

Pretty and Pretty Smart

I don’t know what they put in the water cooler at Logitech, but I want to start drinking it. The Harmony One is another in its long list of affordable universal remote controls. It looks great, is easy to program, and is sweetly simple to use. The Harmony One is as narrow as most single-device remotes, but it’s thinner and surprisingly light. It’s even easier to hold and use. At the business end is a bright 1.25-by-1.5-inch color touchscreen with enough resolution that you can easily recognize the tiny DVD logo on the DVD player icon. The backlit hard keys are distinctly grouped together by function (transport, numeric keypad, etc.). Although the individual keys are only slightly larger than those on an average remote, each has its own unique shape and is spaced far enough apart so that you can easily use the remote for basic operations without looking at it. The Harmony One includes a built-in motion sensor that’s supposed to wake the remote when you pick it up. It’s not super sensitive, though, so sometimes you’ll need to give the remote a quick shake to bring it to life. To recharge the battery, just place the remote in its horizontal charging cradle. My older Harmony 890 is sometimes finicky and refuses to make contact—and therefore doesn’t charge—when resting in its cradle. This one has a deeper well that ensures a solid connection between the contact points on the remote and the charging cradle. By the way, the rechargeable battery is removable and replaceable, much like a cordless phone’s battery. This makes it environmentally friendly, and it won’t force you to buy a new remote when the battery finally expires.
