OT - Plasma TV question

Jay: Rather than a plasma screen, I went with a high-quality projector (at 1/4th the price). Takes just about every input (you'll just love MS Sim on a 6 foot wide display!) from the computer as well as the DVD/TV/satellite/VCR. Inputs are what you'll find on most systems these days...S-video, component or the single F plug. It's an InFocus, model is 2 years old, so I'm sure there are newer/better/cheaper/whatever models out. Best of all, it's a box the size of a large phone book, lightweight, and I can carry it to meetings if I need it. Otherwise I keep it mounted in the frame I built on the ceiling. I haven't seen any projector setups I like, or that have the resolution I want. I want someting I can view in broad daylight. Roger Halstead (K8RI & ARRL life member) (N833R, S# CD-2 Worlds oldest Debonair) www.rogerhalstead.com On the other hand, the plasma tv has much sharper definition. When I zoom out the projector, the pixel density remains the same, but the size of the pixels get bigger, so there's less sharpness. As for a plasma tv -- if you're a Consumer Reports subscriber, check the website - they review this stuff all the time. |

OT - Plasma TV question
Jay,
I am quite fond of the Philips 37" LCD HDTV that I recently purchased at Costco for $2000... I have really loved watching the Olympics in HD on it! I tend to be biased towards LCDs though due to my experience developing the LCDs for the 777 EFIS. Dean |

[...] You'll pay $5000 for a decent one and yes they are relatively dim as compared to the flat panel TVs, either plasma or LCD. $5000 should get a very nice and relatively bright DLP projector. Depending on one's definition of "decent", the price point for that standard starts a bit lower. Pete |

... [...] 3. Use a special screen made for projectors. This is by far the best option, but also by far the most costly. A decent screen will start at close to a grand. Again, I suppose it depends on your definition of "decent", but there are plenty of usable screens out there for a few hundred bucks. No need to spend a grand just to get a quality picture. Pete |

... I would go with a projector, also, but would use a DLP (digital light processor) driven projector. Not sure about the DLP projectors, but the normal DLP units are rather directional in their viewing angle... They look better than LCD or plasma, but only if you are *directly* in front of them... |

Depending on one's definition of "decent", the price point for that standard starts a bit lower. There's a couple guys selling used Sony VPL-PX31 projectors on eBay. They produce about 3000 ANSI lumens. They go for around 1000.00 - 1400.00. It's a fabulous deal. I have about a dozen of them and they perform flawlessly. They originally cost about 7K. Couple things to watch for: The lamp life is about 1500 hours on the high brightness setting. Replacement lamps are about 400.00 for aftermarket units. Take that into account when bidding. The projectors on eBay often have a long throw zoom lens. (That was originally a 3K option.) The zoom lens model is ZM-101. The zoom angle is 3.5X to 5X. That means the projector would have to be 35 to 50 feet away from the screen to produce a 10' wide image. The standard lens is 1.8X to 2.5X. That's the one you probably want so be sure it has the correct lens when bidding. If your looking for plasmas, try www.plasmanext.com. The guy's name is Darren. I've bout at least a dozen 50" units from him. The world of plasma resellers is almost completely scam-infested but these guys have been very good. You don't need a screen. The best projection surface for a room with enough ambient light to read and make notes (most common business meeting scenario) is a wall painted a light shade of gray. That will increase the contrast remarkably. These projectors are native 1024 x 768 resolution. They have a built in scan converter and will accept any current type of signal. They will convert an HDTV to work within their native resolution. Purists will be unhappy with this but I doubt any of your guests will care. And, brightness will trump resolution in any case. Also note that a projected image is much larger than any plasma and much better suited to business presentations. With a 7.5' a 10' viewing area, these will be killer bright. We use them with screen sizes up to 10.5' x 14' and they work just fine with typical dining ambient light levels. Be sure to use good quality video cables to connect these. A typical computer VGA cable is only good for about 10' before the signal quality degrades. Stay away from expensive consumer cables and just get some good industrial grade ones. Let me know if you need a source for them. You may also want a ceiling mount bracket. Original equipment ones are expensive (200.00). I buy them on eBay for around 50.00 or less. Again, let me know if you need a source for one. moo |

What's a "digital light processor"? And who makes these projectors? Any idea on cost? I hadn't even considered a projector, as they always seem too dim. hm, why don't you ask in the proper newsgroup? there are the experts and they can answer all your questions. #m -- DoD staffer's notes from meetings on 9/11 http://flickr.com/photos/66726692@N00/sets/72057594065491946/ http://www.outragedmoderates.org/ |

It was a small tube with 3 outlets very close to the projecting wall, and the laser projected the picture clear and bright. Don't know if this sort of projector died or are already available. #m -- DoD staffer's notes from meetings on 9/11 http://flickr.com/photos/66726692@N00/sets/72057594065491946/ http://www.outragedmoderates.org/ |

Also, please =please= don't stretch a 4x3 image to fit the entire screen. Everyone looks fat and squishy, and it just looks funny. Display it with vertical bars on the sides, in its natural 4x3 format, and save the wide screen display for real wide screen material. And that leads to the question, what about burn-in on a plasma screen TV? I suspect that watching a lot of 4x3 source in its native aspect ratio would be a problem for a plasma TV, no? -- Peter Great thread and timely for me, too. |
