that one can print 10,000 pages a month and not break, and the other can't.
(By "projector" we're talking about something that you plug into your
laptop so the whole room can see the Blue Screen of Death in 12' x 12'
format. Not the ones that project transparent slides onto the wall...)

Check:
- Brightness
- Native resolution
- Size
- Contrast ratio
- Noise level
- Lamp lifetime
- Colours saturation
- Number and type of inputs
- Fancy extras like auto-focus, auto-keystone, USB/LAN control etc.
- Can it be used upside down (for ceiling mount)?

These two are prominently displayed on all the item descriptions.

Contrast and lamp lifetime [and cost!] seem important. None of the rest
seem especially important for what I need.
What's auto-keystone?

customer service.
For occasional use a cheaper one will be OK but for high usage showing
high quality work you would want a dear one. Unless you are paying for
it yourself.

Noise? There's nothing worse than trying to listen to somebody or watch
something and have the horrible loud buzz of a projector in the background.

Makes the image look square on the wall/screen, even if the optical axis of
the projector is not exactly perpendicular to it (good if the projector is
portable, not much use if it is going to be fixed).

Ah. OK. The projector we currently have is pretty much silent. I forgot
that some projectors aren't.

Oh, OK.

BTW, I got a NEC NP60 for our office, because it needed to be compact and
bright. Pretty well satisfied with it (it works well even with the blinds
open), but I wouldn't say it was completely silent.
I see it's only 650 GBP now, XGA 3000 lumens 1.6 kg.

Sharp PG-MB60X:
- 2500 lumens
- XGA
- 31 cm x 28.7 cm x 10.4 cm
- 1000:1 contrast
- 2000 hours lamp lifetime
Acer X1260:
- 2000 lumens
- XGA
- 26.7 cm x 18.7 cm x 8 cm
- 2000:1 contrast
- 4000 hours lamp lifetime
What am I not seeing? It's got slightly less brighness, twice the
contrast, twice the lamp time, and it's about 60% cheaper. Does not compute.
PS. Why do all the "DLP" projectors have 10x the contrast ratios of
"LCD" projectors??
PPS. Not one single product description includes noise data.

Looks nice, but the product information I have doesn't seem to indicate
the presence of a VGA input...
