BenQ W1070 Projector - Performance 2

That's a drop of almost exactly 35%    Although measured Dynamic mode for the comparison, understand that you should get that same amount of difference no matter which mode you are in.

Check it out.  First is Normal (full power) then Smart Eco, then Economic:

The W1070, as you can see from the numbers above, defaults to a slightly cool image - but barely so. The nice thing is that most should prefer a projector that's a little cool, than a little warm (too much red). That the temperatures are very consistant predicts a great calibration.

Ridiculous.  No $1000 projector should be able to calibrate this tightly. Note that the color temperature varies only by 80 degrees.  Most projectors calibrated vary by 200 to 400 degrees.  Even $10,000 projectors.  Sweet!  The result is excellent color.
