Excellent data image quality. The XJ-H1750's data image quality is easily good enough for any business or classroom use. In most color and brightness modes (there are several of each), it offers nicely saturated colors and suitably neutral grays. The only exceptions are for the two brightest modes, where some shades of gray show a tint, and yellow is a slightly greenish mustard color. However, most projectors' brightest modes have problems with color, so that's not really an issue.
Very much on the plus side, the XJ-H1750 handled both black on white and white on black text extremely well, maintaining crisp edges down to 7 point size in both cases. Screens that tend to cause pixel jitter weren't quite as rock solid with an analog connection as with HDMI, but it takes a close look to see the difference.
Better than par video quality. Video quality is just good enough to count as a plus. The XJ-H1750 handled shadow detail reasonably well and it showed only slight posterization on scenes that are particularly challenging to get right. However, image quality is limited by the 1024x768 native resolution, there is a moderate level of noise, and colors have the dulled down look typical of a low contrast ratio. Ultimately, the quality is best described as usable, which is better than many data projectors can manage.
Good audio quality. Audio is another plus. The XJ-H1750's 10-watt mono speaker puts out enough volume to easily fill a mid-size conference room or classroom, and at acceptably high quality. If you need stereo, you can plug an external sound system into the stereo output.
Eco(nomically)-Friendly. The mercury-free light source with its 20,000 hour lifetime -- long enough to last the life of the projector -- is the most obvious eco-friendly feature in the XJ-H1750, but there are others also.
With five Eco modes, you can pick the one that uses as little power as possible while still being bright enough. I measured power use ranging from 122 watts at the most extreme Eco mode to 249 watts at the least extreme, and at 287 and 340 watts in the two non-Eco modes. In addition, you can set the projector to turn off after not receiving a signal for 5 to 30 minutes.
Also worth mention is Auto Eco mode, although it delivers less than it could. What would make this feature truly useful is if it would keep track of the setting for the 1.2x zoom lens, measure the distance to the screen much like an auto focus feature, and pick the brightness level based on the ambient light and image size. Unfortunately, it's not that smart. With a given light level, it chose the same Eco setting whether I was a little over 12 feet from the screen with a 98" diagonal image, or 38" away with a 33" image. Even so, it can still be more useful than not having the option at all.
Outstanding Warranty. Casio's 5 year warranty is longest warranty in the industry. What may be unique to Casio, however, is the length of the light source warranty, at 5 years or 10,000 hours. The 10,000 hours works out to five years worth of eight hour work days.
Interactive-ready. File the interactive-ready feature under extremely minor extras, given that it's an extra cost option, and the XJ-1750's standard throw makes it hard to avoid shadows. If you want to add it, however, it's $249.99 for the software and interactive pen.
