XJ-UT351WN Brightness

Theater Mode2,171 Lumens
Blackboard Mode1,889 Lumens
Natural Mode2,509 Lumens

The Casio XJ-UT351WN fell about 17% short of its 3,500 lumen claim, coming in at 2,920 in its brightest mode. Most projectors measure 5% to 20% below claim. Historically, Casio has delivered a fair number of lumens for the price (and solid state light engine), but Casio tends to under perform their claims more than most. It’s not about whether a projector meets specs, but rather – does the projector perform well for the price? In this case, the answer is yes. 2,920 lumens is plenty bright for rooms that have quite a bit of ambient light. This Casio has a seven-step lamp brightness setting, accessible via the leaf button on the remote, which is equivalent to Eco mode on other projectors. Lowering the brightness 30% on Standard mode, I measured 2,760. Not too shabby.

Natural mode yields just over 200 lumens less than “Eco mode,” at 2,509 lumens. Graphics mode, the next brightest, measured 2,268. Theater came in at 2,171, and Blackboard mode measured 1,889 lumens. Even for the dimmest mode, 1,889 is pretty good. Great job, Casio.

Color Performance

There aren’t many controls to adjust color in the Casio XJ-UT351WN’s menus. Above, you’ll see an image showing the out of the box greyscale performance in Theater mode. The following photo shows the greyscale performance after adjusting the red, green, and blue gain adjustments. I adjusted red to -5, green remained at 0, and blue was adjusted to +5. The difference is very slight, though these small adjustments make the color look a bit more true to the preferred 6,500K color temperature.

 

Contrast

With a 20,000:1 contrast ratio, the XJ-UT351WN is very competitive with other business/education projectors in its class. The Casio offers higher contrast than competing projectors using LCD technology, as contrast is a DLP strength. It will result in DLP projectors having a bit better blacks. We’re not talking home theater quality, but then we’re also not expecting this Casio projector to be used in a fully darkened room!

Audible Noise

Casio determined the XJ-UT351WN’s noise level to be at 34db. That’s not exceptionally loud, if you go by the numbers. I didn’t notice the noise much when operating this projector, even in its brightest mode, though it was certainly audible. The XJ-UT351WN would fare well in a typical conference room or classroom environment, and the noise level should not be an issue.  For perspective, 31-34 db is on the high side, but not uncommon for even home theater projectors running at full power. Count the Casio projector’s audible noise levels to be very good! At 34 db, even in a typical conference room, you’ll definitely hear the fan noise, but you won’t have to shout over it.
