When displaying a full white screen test image, I found the brightness uniformity of the VPL-DW240 appeared very good as did the color uniformity. Also when displaying text and graphics images the focus uniformity was very good and also with good convergence of the red, blue and green colors.
Although Sony rates the maximum brightness at 3,000 lumens, I measured a maximum level of 2683 lumens, using Presentation picture mode and with the zoom set to maximum. Perhaps this is simply due to a sample-to-sample variation, especially dependent on the specific lamp being used. In any case, this is still a fairly bright projector and can compete will other manufacturer's projectors rated in the 3000 lumen range. Also this projector, due to its use of 3LCD technology, will have the same color brightness as the white brightness - more on why this is important can be found - HERE.
