The colors that I use for my PowerPoint Presentations do not project the same
laptop colors when I use a data projector. For example, brown looks green on
the large screen display. What is causing this problem? The projector
(INFOCUS) has been serviced but that has not solved the problem.
 
Let me guess...

You're using a DLP projector.


A "digital light processing" projector uses a new and more efficient
projection technology that employs lots of small mirrors to create images
that are potentially brighter and sharper than the traditional LCD
technology.

The problem is that colors are often not accurate! (Other than that, Mrs.
Lincoln...) Light blue often looks dark blue, yellows look mustard, and soft
pinks...forget about it. We learned this the hard way at PowerPoint Live
2005, where the new crop of Dell projectors shone brightly, set up
beautifully...and looked awful. Last year, we retreated to Epson's LCD units
and were rewarded with much more accurate colors.

It kind of boggles the mind the extent to which DLP technology panders to
such a low common denominator. Sure, white bullets on a dark background will
look fine, as will simple bar charts. What about the rest of us...?

Some things to try:

One that's probably obvious to you, but it's not to everyone: make sure you're
projecting onto a white or at least neutral colored surface.

What do you get when you set your Windows desktop to neutral gray? Rightclick
desktop, choose Properties, then on Desktop tab, choose None for Background,
then use the Color button to set color so that R,G,B values are all equal.

Does the projected image match the laptop display?

Try a different cable.

Is any sort of color management software in effect? Disable it temporarily to
get it out of the loop. The video driver may also enable you to adjust the
color per display; check that as well.

Try a different computer.
