1080p DLP Home Theater Projector Review
August 19, 2013
WHDI. Wireless HD technologies are still in their infancy, and there are more than a few bugs left to work out. The W1500's included WHDI system can introduce some artifacts into the image, the most obvious of which was macroblocking in medium-intensity color fields. This was most visible on test patterns in the 30% to 60% illumination range, but it could also be seen on the standard background of our Playstation 3 game console. We also encountered some synchronization issues when trying to mate the WHDI transmitter to one of our laptops -- the image would appear, then several seconds later it would drop to black again. Bottom line: for mission-critical applications, an HDMI cable is still the preferred method.
Lens shift range is limited. While the W1500 does deserve credit for including any lens shift at all, its range is extremely limited and ultimately only gives you a few inches of wiggle room. This is a limitation of many DLP projectors due in part to the design of the DLP light engine.
No VESA port. The W1500 uses DLP Link for 3D synchronization, which is a fine and capable solution in its own right. But the projector does not include a VESA 3D sync port, so DLP Link is your only 3D option. Several other inexpensive 3D projectors do include a VESA port, making it easy to switch to infrared or radio-frequency glasses systems if desired.
144Hz 3D. Many DLP Link 3D glasses top out at 120Hz, which was the maximum synchronization rate for a lot of first- and second-generation 3D projectors. The W1500 runs at 144Hz, so these slower glasses will not work. While the new glasses are not too much more expensive than the old ones, it is one additional thing that can go wrong when attempting to purchase your complete 3D system. At least one review rolling around criticizes the W1500's (excellent) 3D capabilities because the reviewer accidentally used a pair of 120Hz glasses to do their evaluation.
Menu quirks. At times, the W1500's menu system gave us a bit of trouble. The projector has optional wireless networking, but attempting to enable wireless sync when this module is not present caused our projector to freeze up completely. BenQ has typically been responsive to issues like these and typically releases firmware updates to correct these problems as they are found.
