I'm looking for a reasonably portable projector for use in smallish offices for Powerpoint display and for display of 3D data (VRML, VTK, OBJ formats etc). LG PW800G seems to tick all the necessary boxes (though trading brightness for the LED lamp life). I'm using a normal HP Pavilion laptop with HDMI port - I guess this is suitable? Would appreciate any positive or negative comments.

What glasses would I need with this? Will any DLP-Link glasses be suitable?

Also would welcome any suggestions on appropriate 3D viewing/browsing software to produce the necessary stereo-pair output. Presumably would need to use the laptop's mouse to fly around the model. So far I have only 2D browsers for VRML.

If the LG projector is not suitable, an alternative that I have identified is Optoma H183X but this is heavier and bigger - much less portable.

There is no chance in the world I would even consider this for any commercial use. Read the review on this one. The projector is DIM, DIM, DIM, DIM!!!

400 lumens, real world, is about enough light to work on a 8 square foot screen. That's about a 52" diagonal. Or, you could buy a flat panel display, of similar size, for about the same amount of money.

Conference room projectors don't use LEDs, they use laser light sources, and they tend to be a good deal pricier for the design of the solid state light engine. It's rarely a good call to go this route, and I would stick with an Epson LCD projector with a 5,000+ hour lamp life and $100 replacement lamps instead. Think 3,000-4,000 lumens or more for quality results. For 3D, the manual should recommend 3D glasses which will work. It is true though that DLP will work with more 3D glasses using standard DLP Link glasses with their 3D. Be aware that many computer based 3D systems actually use RF emitters and specific glasses for their 3D cards, which have nothing to do with the projector, so this can be hit or miss depending on the source and graphics card in use.

Many thanks for the helpful comments! I'm not even considering the projector for conference room use - it's for small groups of up to a dozen people, generally in a small office. However, the image brightness was the one issue that bothered me. Even though LG claim this is suitable for "business" use, it is so much less bright than similar specification Optoma or Benq (or other) projectors which do the same job, but with incandescent light source, that I was suspicious. I guess portability has to be compromised !
