Q. What type of TVs use a lamp?
A. Rear Projection DLP TVs use a lamp, with the typical lamp life ranging from 5,000 to 8,000 hours. With normal use, that translates to many years of TV viewing. You may never need to replace your DLP TV lamp (depending on how long you own the TV), but if you do, the typical replacement lamp costs around $200.
Q. What is screen resolution?
A. Resolution refers to the number of pixels being used to project an image. In general, the larger the numbers the better the resolution and the picture quality. Current HD programming tops out at 1920 x 1080 pixels. In fact, HD is generally about six times sharper than standard TV, and can be as much as ten times greater.
Q. What's the difference between 720p, 1080p, and 1080i?
A. 720 and 1080 refer to horizontal pixel counts. Both 1080p and 1080i HD broadcasts offer higher resolution than 720p broadcasts. The "i" indicates that the TV draws images using an interlaced method. The "p" indicates that the TV draws images using a progressive scan method. In general, progressive scan renders images faster and produces a more detailed, more film-like image. This means 1080p offers the highest quality currently available.
Q. What do the "i" and "p" mean?
A. The letters "p" and "i" indicate the picture-scanning method - progressive or interlaced. In interlaced scanning, the on-screen image is created in two split-second passes, drawing all the odd-numbered lines first then going back to fill in all the even-numbered lines. In contrast, progressive scanning draws each frame sequentially in a single pass to create a smoother, cleaner picture. So, progressive scanning is theoretically better than interlaced scanning.
Q. What do I need to watch HD broadcasts?
A. Your choices for watching HDTV are via over-the-air broadcasts, cable or digital satellite.
Digital Satellite HDTV
Q. What's the difference between a "3D-ready" and a "3D-capable" TV?
A. 3D-ready TVs come with the necessary emitter built-in; 3D-capable TVs do not, so you'll need to add on a separate one for 3D-capable TVs.
Q. What do I need to watch 3DTV at home?
A. You'll need a TV labeled "3D-ready" or "3D-capable", a pair of 3D glasses for each person watching, and a 3D video source such as a 3D Blu-ray movie.
