I am looking for a projector that is good for my conference room. The room is 25x15. We need something the will project Excel spreadsheets really clearly. Current we are using an old epson powerlite s5. This is a 800x600 resolution projector. It is not clear enough to see. I believe we need a 1280x768 resolution projector to be able to see the excel sheets clearly. Any input on models or where to look would be great.

The most typical widescreen resolution for business class projectors is 1280x800 which works out very well for typical users.

The question becomes more about screen size, as you will need a 16:10 projection screen of some sort for best results.

Then, the brightness of the projector can be determined with some pretty basic math. Take the square footage of the screen, and multiply it by 80 lumens, and that will give you the brightness of the projector that is necessary.

Then you just have to take any other special considerations into account. That may include high ceilings, a specific projection distance that is desired, or a very bright room (which means a brighter projector).

Assuming about a 50 square foot screen, then this is the list I would work from...

I'm a big Panasonic fan, so this model would be near the top of my list...

Thank you. Most of the time the lights will be off so it will be really dark in the room. I can probably do like 3500 lumens then correct?

The projector is mounted on the ceiling and is pretty close to the screen. Does that matter? Company is trying to spend under $1000 dollars for this.

Also another thing, how big does the contrast ratio effect the image. Does this matter a lot?

The goal is to achieve no less than a 12:1 contrast ratio when the projector is in use. The general rule is 80 advertised lumens per square foot in a typical boardroom to achieve this. The goal should NEVER be less light output as this will almost always have a negative impact on image quality.

Yes. Screen size and lens distance and height are extremely important. If the projector can't be placed anywhere in the room, then it has to fit the specific criteria that is expected for it.

The company should not set a budget at all until they know what the options are which meet their criteria for performance. It's nice to want a brand new car for under $20,000, but when you start putting together the list of things you want that car to do, it may not be available for the budget, and the budget will need to change or your requirements have to change.

CONTRAST RATIO: Contrast ratio matters, but projector specifications are almost completely irrelevant in a boardroom. This is because white walls, and fluorescent lights devastate contrast. A 10,000:1 contrast ratio can drop to 50:1 if a single candle is lit within a room. So, it is the lumens per square foot which create the contrast in rooms which have lights.

Obviously, you can turn lights off, as you suggested, but then it may become a safety issue in any office space, or it may not be convenient to the presentation which may need people to write things down and move about comfortably.

The Panasonic I listed is only $1,300 and is where I would start and stop my consideration I have to say. It's a reliable manufacturer with a projector which will deliver quite nicely.
