Infocus IN36 review


The IN36 is the best-looking office projector in the group, with its sleek silver body and matt-black top and bottom.

A solid, but not outstanding business projector, InFocus' IN36 is a compact unit, but it suffers from some colour and contrast issues that, even with calibration, cannot be fully remedied.

InFocus Replacement Lamp


This item is still on back-order for me and I have not received it yet. Once we get it in, I''ll be happy to review it but, probably won''t be able to until we replace the lamp. Hopefully not until a long time.

InFocus = Expensive paperweight


Lamp failures are one of the risks you take when dealing with projectors. But why risk buying from a company that only stands behind it's product for 6 months? My advise: find a brand that backs it's lamps for 1 year or more.

Great picture, easy to use interface. Lamp brightness was sufficient, even with lamp on

Lamp ruptured after only 250 hours of use. InFocus only warrentys the lamp for 6 months. I was in my 7th month of overship, thus leaving me with an expensive paperweight. InFocus offered me a new lamp for $500

excellent for its class


Bought this to replace our IBM which I believe was way below par. We have a bright office with lots of natural light and this unit provides plenty of lumen's to compensate. Newegg has a very competitive price. Once again a great company :)

Easy to set up ; Lots of light ; Sharp display ; Fit and finish excellent

None thus far

Product Specifications

You've prepared everything to ensure the big presentation goes well - your projector should be just as capable. InFocus' new Work Big IN36 is the flagship meeting room projector - designed to help you present with power and ease. Featuring 3000 lumens, this projector is bright enough to use with the lights on or the windows open, leaving you time to rehearse your pitch and not fuss with the blinds. All of this power comes with great flexibility as well, such as digital keystone correction, RGB color-adjustment, an impressive 1000:1 contrast ratio and multiple installation options. With the IN36's connectivity options, including a serial interface connection, multiple computer inputs, S-Video and more, you'll never have to wonder if your meeting room will be compatible with your projector. Simply plug in the IN36 and you'll be integrated into your existing IT infrastructure. The IN36 is extremely easy to set-up with the included color-coded cables, and a breeze to move from room-to-room, so you can be influential anywhere you choose. And maintenance is a snap - there are no filters to clean. An instant feedback LED interface takes the trouble out of troubleshooting, and audible cues let the user know when the projector is starting up, powering down or in need of service. The sturdy, compact design provides easy mobility for all your projection needs, no matter where the meeting room may be. In addition, the included cable tie-wraps mean there's nothing to get the way of your next big presentation. 3000 max ANSI lumens provide an image that will illuminate any meeting, and a quiet <35dBA operating volume ensures you'll be heard perfectly. The IN36 gives you exceptional features and dependability at an affordable price, so you can meet both your presentation and financial objectives.
