New plasmas have 60,000hr half-lifes, that is to say, 8 hours per day, every day, for 10 years before it degrades. |

Well, the colour wheels wear out in about 2.5-3 years, and need to be replaced at those intervals. They're about $300-400 a pop depending on the manufacturer. |

DLP:
- A new way of projecting stuff really big. Before for projectors you would have a tiny CRT, and a magnifying glass would blow up the picture and project onto the screen.
- With DLPs, a single beam of light is shot at a rotating colour wheel. The wheel has the three primary colours, and for each frame, each colour is drawn at one time. They do it so fast that all three colours are drawn seperatly, and it just looks like one picture.
- When the light passes through the colour wheel, it then hits a mirror which sends the light to the right part of the screen.
Pros:
- Cheap, like most projectors are.
- Nice quality compared to old projectors.
- They dont burn in like regular projectors. With the old style you could easily burn in that tiny CRT, because it was so bright. here you dont really have to worry.
Cons:
- Replacement costs. For a projector, you have to replace the bulbs because they burn out. That could set you back 300-600 depending on the models.
- As Cale said, you could also have to replace the colour wheel, but in my experience its more the motor that drives the wheel that is the problem. It becomes cloged by dust, and could seize up.
- So in the end, they are cheap to buy, but they have replacement costs.
- Rainbow Ghosting. Because the colours are drawn one at a time, there are some side effects. If you get a chance to see a projector up close, go up to the wall its being projected at, and wave your hand back and forth. You will see each different colour. Now this can also apply to fast action shots, and if you move your head back and forth. So the picture/colour isnt as defined as other technologies.
Projector vs TV:
- Essentialy they are the same, but the execution is a tiny bit different.
With projectors, you draw the image on the wall, and with TVs, its on the built in screen. Either way you have a bulb, a colour wheel, and tiny mirrors. |

One more thing. If you are ever in the market for a DLP projector, do your research.
Some of the companies produce two different versions of the same model.
1) has a home theater name and badge slapped on it
2) the other one will be a 'computer' model.
The home theater model will be waaaaayyyy more expensive, but its the exact same hardware. Its amazing what these tech companies get away with when they cater to the home theater crowd. |

Im gonna be using terms ive already explained so:
All computers display stuff in progressive scan. All tv signals (normal, not HD) are in interlaced format.
A tv card just turns the interlaced singal(240i), into a progressive signal(240p).
And, just because you have a progressive scan signal now, does not mean you have HD. Normal cable is still transmitting at 240i.
ATI did come out with a HDTV card, but it does no good for people in Canada, because HD signals are not broadcast for free here, and so the card is not sold here in Canada.

| So if you were the one getting a big screen, what would you get, DLP, Plasma, LCD Projection, or LCD? We're talking 40" or bigger. |

Honestly, with the new stuff is where I start to loose touch. I would definitely suggest reading a dedicated HD forum, like http://www.highdefforum.com/
The people on there are more educated about specific tvs and models.
Plus I will never buy another Sony product again, because I really do not agree with their business practicies towards the consumer and preserving market stability.:whip:
But in terms of technology, and cost/quality(because I dont have alot of money) i would go with a projector, and not a projection TV. If you have the space, they are great because first of all, you can scale them to what ever size you want, and you can usually hook up a computer with no problems.
If you play a lot of video games, projection TVs are very dangerous, because they tend to burn in. I think with LCD projection tvs, that problem maybe solved due to the fact that they dont use a CRT projection lamps anymore.
I still need to get back to Tygon, so hopefully i can do some reading this week, and get back to both of you. |

My uncle has a 60" LCD projection and to be honest I have never seen anything so awesome.
Watching HD PGA golf on that TV was unbelievable and playing PS2 NASCAR was even better. |
