Mitsubishi WD390U Projector: Color
Color quality varies significantly depending on mode. Naturally, the brighter modes are those with the least good color. Still none of the modes look terrible, even if the brighter modes exhibit the typical DLP problems with bright reds and yellows. The Theater mode is the best looking although Standard is brighter, still looks pretty good, and Auto is usually very bright. Presentation mode is the brightest.
All these images were taken with the same exposure except Theater, which is the least bright. The Theater mode image was taken with a brighter exposure so you can get an idea of the color handling. If at the same exposure as the others, the images would be too dark to really learn anything.
Presentation Mode: This is the brightest mode, although User and Auto are normally right there. Color is acceptable, although there is a bit of green/yellow cast. Bright reds tend to be dark wine colored (not unusual at all for DLP projectors, and bright yellows tend to be darker and have a strong green component. Still, fine for your spreadsheet or even a typical pie chart.
Auto Mode: Auto mode will vary, depending on the source, but typically it sticks to apparently the brightest modes.
Standard Mode: The best blend of good color and good brightness. The WD390U still has plenty of brightness in this mode which should be fine except when you need the most accurate color.
Blackboard Mode: Don't worry about the color, if you are projecting onto a blackboard, what do you expect? The attempt here is to punch up colors so they still are visible on a dark surface.
Theatre Mode: Theatre mode on, the WD390U looks pretty good. It would certainly do a respectable job if you brought one home for the evening. Notice how by comparison, most of the other modes look too dark.
Whiteboard Mode: Perhaps most similar to Standard, but it measures a little less bright. The balance on images seems to be a touch less dark than Standard, making Whiteboard mode a good general mode, if not a bright one.
