Casio XJ-H1750 Projector
with LED/Laser Hybrid Light Engine

Marc Davidson, March 22, 2012

Test Results and Connectivity

Bright image with wide brightness range. The XJ-H1750 offers both a far larger brightness range and more levels within that range than you might expect, with two non-Eco levels, Bright and Normal, plus five Eco levels. In addition, it offers five color presets that also affect brightness, with those presets available only in the Eco modes. This works out to 27 different brightness levels.

I measured Bright mode at 3716 lumens, Normal at 2972, and the five Eco modes at 2405 to 1410 lumens with the default Standard color mode. The color mode settings drop the brightness further, down to 606 lumens for Theater mode in the brightest Eco mode. You can go even lower by combining the lower brightness color settings with the lower brightness Eco modes.

Unlike traditional lamps, the XJ-H1750's hybrid light source doesn't gain additional life by using Eco mode. However, lowering brightness lowers the fan noise considerably, with the fan winding up or down noticeably when you change brightness. Casio says the range is from 35dB to 28dB, but if you're sensitive to fan noise, it's helpful to know that it gets quieter with each step down the brightness ladder.

Excellent brightness uniformity. Brightness uniformity for the XJ-H1750 is excellent. I measured it at 79%, which is a good score. Just as important is that the brightest and dimmest areas are far enough apart, and the change between them gradual enough, that I didn't see any variation across the screen, even with a solid white image.

Good connectivity. The back panel on the XJ-H1750 offers all the connectors you'll likely need, including an HDMI port for a computer or video source, two VGA ports for computers or component video, a pass-through VGA monitor port, and both S-video and composite video inputs.

Audio ports include two stereo miniplug jacks, with each one paired with one of the VGA ports, and a set of stereo RCA phono plug jacks paired with both the composite and S-Video port. A stereo miniplug output lets you connect to an external sound system.

In addition, there's a USB A port that will let you plug in a USB memory key to read JPG files directly. It will also let you plug in the supplied WiFi adaptor to connect directly to send data images to the projector from a computer or most Android, iOS, and Windows smartphones and tablets. Finally, there's an RS-232 control port for a computer or third party controller; a LAN port for data and for controlling the projector over a network; and a USB B port, so you can connect to a computer to use the optional interactive feature.

Sheesh! Why are we dragging our heels so hard on the resolution, going up half a step at a time at big cost? By the time projectors make it you'll be able to walk into Home Depot and leave with a 4x8 ft flat screen for ninety bucks.

is appreciable .other lcd and dlp players should have to offer extended lamp warranty to compete with this product

A 1024 x 768 resolution projector? For over $2,000? In almost April 2012? No.... I don't really think so. Although I did love the 1990s so much.

The 10,000 hour warranty does not sound all that much, either. But the rest out there is even worse than this for PJ warranty.

There is a great difference between a laser beam bounced off a mirror and directly at your eye vs. projected light spread across a 80" or so piece of vinyl with a sprayed particle coating. These projectors are just bright enough to see a picture, and although they are improving... they are hardly bright enough to burn your retina... I would however suggest backing a little further away from your microwave while it is active... :)

I wonder if these lasers could harm the eyes as at the end of the day they are [%#^&*&*@] burning lasers.What they can do is amply demonstrated on many youtube videos.What we are seeing is reflected laser light.Isn't it ?

Wow, great leap for Casio! Now, bump up the lumens to 5k, and make it HD and I'm in for 4 or 5 units.

But this model should be great for a large variety of uses right now!
