This is THE real wave of the future… Finally, we’ll get to leave the whole stupid bulb replacement game behind! LED light source has lifespan specs of 20,000 hours! LED’s are the low temp light source we all love in those nifty new flash lights these days. Contrast specs will also be a thing of the past, they’re rating this model at 100,000:1!! Looks like they’re still working on getting the light level output up to snuff, this was only rated at a very anemic 800 lumens… i’m sure that’s only a matter of time as well. Vivitek’s already got a 1080p model out… and it’s only $14k! 🙂 Endgadget.com’s coverage ProctorCentral.com’s coverage Starts to make sense why we’re seeing this technology pop up in the pico projector end of the spectrum at first… low res, low brightness, low power, low footprint all combine for a synergistic package at the moment. I just bought a bulb technology projector (LCD based Epson Home Cinema 720)… hopefully by the time my bulb is burning out (3 years??) LED projectors will be down to mainstream prices.

- ProjectorCentral.com (4/12/01): “Is SVGA enough for good video?”
- ProjectorCentral.com (9/30/04): “DVI and HDMI Video Connections” – so HDMI isn’t some magical cure-all for long distance video cabling (at least it wasn’t circa 2004, perhaps this gap has been closed at this point… i shall soon find out… I’m getting a freebie 25ft HDMI cable with recently ordered projector, so build quality could be iffy… and i’ve gotta adapt it off of my DVI video card which probably drops a couple impedance points at the juncture)
- ProjectorCentral.com (5/4/05): “DVI and HDMI – Copper or Fiber Optics?” – HDMI over copper should hold up over 25ft but that’s max with solid quality, after that you’re going to see some bad juju.
- Forum.Ecoustics.com (2/14/05): “DVI/HDMI vs. Component Video — Which is Better?” – excellent coverage… finally someone makes some point blank statements of difference: “Analog component video is an extremely robust signal type… DVI and HDMI, unfortunately, are not so robust … For reasons known only to the designers of the DVI and HDMI standards, this very sound design principle was ignored… It depends upon your source and display devices, and there’s no good way, in principle, to say in advance whether the digital or the analog connection will render a better picture” (booya)
- And it’s much of the same tossups going on with VGA vs Component from what I’ve read so far.
So basically you just have to try them all with your particular equipment… anything is fair game on what’s going to actually look best. Some other great writeups from these guys:
- “The Technology War: LCD vs. DLP” – excellent coverage of the limitations inherent in either technology… DLP color wheel at low speed = more rainbow effect but brighter so that’s why it’s common in business projectors (static images, brighter rooms, etc)
- “1080p vs. 720p — Which is best for you?” – not bad
They have an absolutely dismal presentation for the amount of excellent hard core data they have to provide… here’s the root “commentary” list where i pulled these. And this is an excellent feature finder drop down box filter search.
Main standout feature is ultra “short throw”… drives a 40” display at only 1.5 ft away from the wall! (2.5 ft = 60” display, 4 ft = 100”).
I’m interested in something that will support projecting to the ceiling from a bedside table in addition to the usual setups.
Wondering if the short throw would provide for easier location swapping… less mounting required…set it on top of something close to desired wall and go.
Was hoping to drive it from my mini tablet pc for more varied locations but am worried that it’s VGA only output isn’t going to be very satisfying image quality… I do have DVI-I output available from primary desktop PC in living room area which should be top notch. Reviews:
- $1020 including APO shipping from “ProVantage” a reputable dealer (right at the top end of my desired budget)
- 1024 x 768 native resolution (1600 x 1200 max input so supports 720p and 1080i HDTV inputs with down scaling… 720p is technically 1280 x 720 so it doesn’t quite nail that resolution natively but there are many LCD/Plasma TV’s which get away with calling this 720p so it must be fairly “ok”)
- all the common video input types…s-video, composite, PC VGA and even digital (DVI-I which is adaptable to HDMI)
- great brightness/contrast specs = 2500 / 2500
- good lamp life = 3000 hrs
- low noise = 30 dB’s
- ceiling mountable (mount holes and flip image mode)
- looks to be a decent remote control
- 3 year warranty on parts/labor, 1 yr on the lamp (both very typical)… looks like lamps are about $300-$350 which is a little high but common
- – definitely a business class projector – there’s a well known “rainbow effect” with the ‘slower’ DLP hardware typically used in business class projectors vs true “home theater” projectors… it can bother certain people while running moving images… I don’t know whether we would notice this or not.
- – does NOT come with a case
Anything important that I’m missing??
All the short throws I’ve found are definitely business class and not true home theater.
The more I take measurements around the apartment I see that there is plenty of throw distance as long as I can setup decent ceiling mounts so starting to think I’m shoehorning for not the best reason.
