Dell 3100MP is a Optoma EzPro 735 OEM also OEMed by Sharp as the PG-M15XU....

Dell version is modified a little from the Optoma...

Not sure where Dell got it specs from or if this is a dumbed down version of the EzPro.

EzPro 735 is 1100 lumens, 500:1 contrast.

Probably just being more honest with their specs. Most projector manufacturers blow their numbers WAY out of proportion.

This CR is very low. In real life most if not all are above 400:1

and thats a low ratio compared to so9me that are a true 800:1

Indeed I would stay away from this one for HT use.

I tend to agree dell may be more honest about their contrast ratios. This review seems to have a good opinion about the dell projector infact they liked it more than Hp XB31 projector for almost a $ 1200 less Dell review . Anyone got this PJ and have a first hand expereince or know of any other reviews of this product. In general dell has always made good products for a cheap price so far.

Anyone considering the Dell 3100MP DLP

projector, should be warned of 2 problems:

1) Keystone does not work correctly with

progressive YPbPr inputs. You'll get

a green border surrounding the image.

2) Contrast and brightness do not work

correctly with all interlaced inputs.

When the contrast is decreased, black

becomes brighter! When the contrast

is increased, black becomes darker!

Dell's technical support is useless.

"We can't work with all DVD players.

There's a problem with your DVD player.

We only guarantee the projector to

work with a Dell product. What you're

doing is like putting a GM motor into

a Ford car."
