The LV-7490, Canon's First 4000 lumen,
XGA, portable LCD projector

Elaine Go, October 4, 2011

Limitations

Short zoom and fixed throw angle. The Canon LV-7490 has a 1.2:1 fixed throw angle lens, which means throw distance options are limited. For a projected image size of 100 inches diagonal, it has a throw distance range between 11'7" and 13'11".

The throw angle offset is measured to be -8%, which means that 8% of the vertical height of the image appears below the centerline of the lens. Due to its slight negative throw angle, if you place the unit on a conference table you will most likely need to tilt the projector upward to get the image high enough on the wall, then use keystone correction to square up the image. In a permanent ceiling mounted installation, you may wish to use a drop tube to lower the position of the projector in order to avoid tilting and keystone adjustments.

No digital input. The LV-7490's connection panel lacks a digital input. While DVI is less ubiquitous than before, HDMI is becoming a common feature on presentation projectors. The absence of HDMI requires separate audio cables to use the onboard sound system.

Light loss in Eco. According to Canon, the LV-7490 has a lamp life of 3000 hours in full power mode and 5000 hours in Eco 2. Eco 2 imparts a 51% reduction in lumen output which is a more substantial drop in brightness than average for this class of projector. So keep in mind that if you are buying the LV-7490 anticipating a full 5000 hour lamp life, you will need to run it in operating modes that put out less than 2000 lumens.

Conclusion

The Canon LV-7490 is an appealing choice for presenters who operate in different venues due to its high brightness, reasonable portability, and its ability to tailor lumen output to many difference sizes of audience and rooms. The preset modes are capable of handling a variety of content, while easy upkeep and low fan noise make this a good choice for schools. Those who might want to use its onboard speakers will wish that it had an HDMI port, and those who routinely use it table top in a conference room will probably prefer a higher throw angle. However, the LV-7490 produces a strong, dynamic, sharp picture for presentations. At street prices at or under $1,000, it is aggressively priced and an excellent value in the 4000-lumen class of high-brightness portables.
