Test Results and Connectivity
Bright image with wide brightness range. The XJ-H2650 offers only one color preset for its two non-Eco modes, but five presets for each of the five Eco modes. The 27 possible combinations translate to both a larger brightness range than most projectors offer and far more levels within that range.
Bright mode came in at 2985 lumens on our tests, and Normal mode at 2503 lumens. The five Eco modes ranged from 2068 down to 1156 lumens using the brightest color preset. Other presets drop the brightness significantly, with the Theater preset coming in at 541 lumens with the brightest Eco mode. Combine the lower brightness color presets with the lower brightness Eco modes, and you can drop the brightness even further.
Note that using Eco mode doesn't lengthen the life of the hybrid light source the way it does with traditional lamps. However, it makes a big difference in fan noise. I'm less sensitive to fan noise than many people, but in this projector's brightest mode the noise was distracting from ten feet away. Fortunately it gets quieter and less annoying with each step down in brightness. It's still audible, but tolerable for my tastes, from ten feet away in the brightest eco mode, and almost inaudible from two feet in the most extreme eco mode.
Also, though Casio's portable projectors can generate more than their fair share of heat, neither the XJ-H2650 itself nor the air from the cooling vents seemed unusually hot.
Brightness uniformity. The projector also scored well on brightness uniformity, at 78%. Just as important, the brightness changes gradually enough between the brightest and dimmest areas that, even with a solid white image, I didn't see any variation across the screen.
Good connectivity. The XJ-H2650 back panel 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, and both S-video and composite video inputs. For output, there's a pass-through monitor port and a stereo miniplug for an external sound system.
One nice touch is labeling that shows which audio ports are paired with which image inputs, with a line connecting each of two stereo miniplug jacks to the VGA port it goes with, and another line indicating that the stereo RCA phono plug jacks are paired with both the composite and S-Video ports.
Other connectors include a USB A port that will let you plug in a USB memory key to read JPG and a few other file formats directly. It will also let you plug in the supplied Wi-Fi adaptor, which will let you connect directly to the projector and send data images from any Windows or Mac computer or most Android, iOS, and Windows smartphones and tablets. Finally, there's an RS-232 port for a computer or third party controller; a LAN port for data and for control over a network; and a USB B port for connecting to a computer for the optional interactive feature.
