Preset Image Modes
This Epson 1985WU serves up a healthy assortment of picture modes. The brightest is Dynamic. Presentation and Theater offer better overall color, as expected, but are still extremely bright. Those two don't look significantly different from each other. As expected, Dynamic mode is strong on yellows and a little extra green, but mostly yellow. Still, it looks a lot better than a great many projectors' Dynamic modes.
Above: Following a sampling of four assorted photos of projected images, are a sequence showing the different modes on the same test image, and at the same exposure. You can tell which mode is which by looking at the menu on each photo. Of interest, the color mode choices vary with the input. For example, when viewing a video source (DirecTV over HDMI) the menu included a Sports mode. By comparison, when feeding a computer signal (MacBook Pro over HDMI), Sports mode was gone, but both Photo mode and DICOM mode appear.
In addition the reds look at least good in all modes, whereas many projectors, in their brightest modes, reds come out pretty dark - like a nice merlot red wine. Overall, colors in the major modes are well balanced, and well saturated - there isn't a really ugly mode among the group. For those that need color matching there is the usual sRGB mode - you can see that in the photo gallery as well. The Photo mode (judging by my eye) is setup with a less contrast than Theatre, and perhaps a touch more saturation. Whiteboard and Blackboard modes for just that, with Blackboard having a definite color shift toward red and a lot of contrast. They help if you are working on those "not typical" surfaces. Finally that leaves the DICOM Simulation mode, which does support color, but is designed specifically to work to the medical films standard in contrast, etc.
Overall Picture Quality
The short version is that colors are bright and vibrant. Even in the brightest mode dynamic color balance is reasonable if strong on yellows. Other modes are even better, with reasonably good color accuracy (without any adjustment). Overall the color temperature, contrast, and other aspects of the image vary from mode to mode, but most folks will find that Dynamic is acceptable when maximum brightness is needed, and the other modes look good to great for presentations, etc., including those loaded with videos and photos.
We did not test the picture quality of Epson's DICOM simulation mode, we will just have to assume it does, as claimed meet the standards required for using the Powerlite 1985WU for instruction using medical films.
If there is one "weakness" to the picture quality, that would be the black level performance. Fortunately, overall that performance is still reasonable for a projector that is likely to be used in a room with at least some noticeable ambient light - and that, in turn, negates significant differences between projectors when it comes to black levels. So, it is a potential weakness, but one that few will have the opportunity to observe due to the lack of opportunity to project in a very dark room.
Score the Epson overall to be rather excellent at picture quality. There are some commercial projectors really designed to offer serious home theater level picture quality and color accuracy, but those would typically be far, far, more expensive projectors, or far less powerful ones.
