Mitsubishi WL7200U Color & Picture Quality
To start, I connected my laptop to the WL7200U via HDMI and fed the projector its native resolution (1280 x 800). The WL7200U displayed a sharp image that is notable for its accurate, well-saturated colors in most modes. Colors were quite accurate in any color enhancer mode, with the exception of a slight greenish cast to whites in the brightest modes. Even so, colors appeared natural, without the normal darkness in reds or yellows. Dropping down into Theater mode improves the color over Presentation or Standard, while still putting out over 4000 lumens. As a practical issue, unless your presentation is dependent on very accurate color or maximum brightness is not a concern, the Auto (or Presentation or Standard) mode is your best bet for most presentation uses.
As a result of the good color, photo presentations are excellent with the WL7200U, particularly in Theater mode. As mentioned in the Setup and Menu section of this review, there are a number of adjustments available to improve the picture quality. If you need to increase the contrast of your presentation, the gamma control will allow you to keep blacks from looking gray and vice versa. Similarly, the red, green and blue grayscale adjustments will provide the proper basis for accurately displayed colors at any level of brightness. Not having any X-ray film to display, I was unable to check the effectiveness of the Clear and Blue Base modes, but it’s a feature that should have a lot of appeal in medical schools.
I also connected my laptop to the WL7200U via the analog VGA connection and there was no readily apparent reduction in color depth. There was the usual minor change in picture quality and depth of color one usually experiences going from a digital to analog connection.
There is a movable electronic zoom (designated magnify) that allows the user to zoom in on a particular section of the screen.
Moving to higher resolutions and aspect ratios than the native resolution, the WL7200U proved to be a solid performer. As seems to be the norm these days, there is little difference with the higher resolutions. Switching to 1600 x 1200 and then 1920 x 1080, the WL7200U was still able to provide readable text of any size, with virtually no distortion. Unlike DLP projectors (which use a single panel with individual colors projected through a color wheel onto the panel) LCD projectors (which use separate panels for red, green and blue, and are usually pixel converged through a prism and the lens) can often be prone to color fringing around smaller lettering. This was not the case with the WL7200U, as small text remained quite readable and there was very little color separation or overlap. This also was the case when dropping down to XGA (1024 X 768) resolution, where the displayed text looked essentially the same as it did at the WL7200U’s native resolution.
