InFocus Work Big IN34


The InFocus Work Big IN34 is a DLP business projector with a native resolution of 1024 x 768. Designed primarily for business presentations, the IN34 ...

Attractive design, good resolution, included remote control

Poor colour reproduction, overbearing white levels, washed out black levels

If you are only planning to use it to office presentations, the InFocus Work Big IN32 may suffice but keep in mind that the colours it produces are not accurate.

InFocus IN34


A versatile mid-range projector priced competitively for both the home and business user, the InFocus IN34 has a wide range of connectivity options, is quiet, has reasonable image quality and is portable as well.

Excellent Projector


I am using this to give power point presentations and it does and excellent job.

The case that comes with it doesn't have a lot of room for the power cord.

Bright, but terrible yellow/green reproduction


This projector is extremely bright out of the box.

All of the yellows turn brown, after doing an RMA and spending an hour on the phone with them and making it to tier 2 tech support.

Nice and bright--come colors washout


This is a great projector for the price (assuming it doesn't break down any time soon). It also comes with an accessory bag, which you can actually use to carry the unit around in.

This monitor is perfect if you need 1024 x 768 display and will be viewing in a lighted area. When I turned it on in my conference room, it was nice and bright ; This is also a tiny little thing and very light. I didn't realize that when I bought it...

Some of the colors are a little washed out. The blues are a little grayish, for instance
