Optoma HD25 Home Theater Projector Review
Color adjustments. While the HD25 includes a full color management system, it does not have separate gain/bias adjustments for red, green, and blue. These adjustments, used to tweak grayscale color temperature, are arguably more useful than gamut adjustments -- especially since it is exceptionally difficult to adjust color gamut without the use of a meter. Most home theater projectors, including the cheap ones, include the ability to adjust both gain and bias for red, green, and blue. The HD25's single-slider solution is better than nothing, but not up to par with most of its competition. It doesn't help that these controls are tucked away in a submenu with the color management system, on a completely different page from the actual color temperature control.
DynamicBlack. The HD25's DynamicBlack system is supposed to adjust the image to intelligently increase contrast. What it actually seemed to do was occasionally increase fan noise for several seconds at a time without much of a tangible effect on the image itself. The change in fan noise is much more distracting than if the fan had just been loud from the start, and it can pull you away from the content you're viewing. DynamicBlack is not recommended for home theater users.
Locked image presets. The HD25's four preset image modes are useful, but they are not adjustable. If you change any of the projector's controls, the HD25 shunts you over to User mode. There is only one User memory setting, so be careful not to overwrite your own settings.
