Wireless Support for iPad and iPhone
BenQ isn't the first to offer iPad, etc. support, but it is one of the few so far. . Remember, there are several million new iPads are being sold each month, and quite a few belong to people who present - teachers, managers, executives, scientists, doctors... To give you an idea of how prevalent they are becoming, I checked out the analytics for projectorreviews.com. Pad and iPhone already combine for 13% of our total visits!
The BenQ LW61ST projector requires an optional dongle for it to wirelessly
Certainly, as an owner of an iPad and a MacBook Pro, when I'm traveling, I'm more than happy to leave my Mac laptop behind if I can (cutting the load by a at least 8 pounds - 3.6kg) , and present from my iPad, given similar abilities. I've got a keypad for the iPad, so I really can do most of what I do with my laptop, about as quickly. As I see it a good iPad interface is a real benefit for a significant number of road warriors and other presenters.
"Eco" - The Laser light source way
While there is no full power vs Eco mode choice, the LW61ST projector and it's LX60ST version, these projectors have an "eco" feature of their own. With most projectors if you want to pause presenting for a few minutes (or seconds), say to make a point, or use some other technology, your projector lamp is still running at full, or eco power mode, drawing a couple hundred watts or so of power. With this BenQ and its laser light source, you can let it rest - without shutting down a lamp, and still drop brightness by 90%. With those other projectors, they will be drawing at least 75% of full power, unless you shut down the lamp, which, when you can, means a slow shut down, and a long get back to brightness, rather than the instant, user friendly BenQ. For those that take advantage of this ability - to blank the screen and reduce power consumption, this can be a noteworthy additional reduction when it comes to cost of operation. There is also an "eco" and a "standard" mode as well.
The most impressive thing, though isn't efficiency, or savings on bulbs. You are already paying more for this projector's light source, so whether there's a cost savings longterm, will likely be more based on how heavy the usage.
I'm impressed with the picture quality of this laser light engine. I've been sitting here watching CNBC for hours while writing. I've watched movies on it (ok 2), and used it with my Mac on data, and web surfing. What I don't notice, is that this is a laser. I'm not seeing any of the strange artifacts associated with laser projectors. I think of the massive shimmer of the laser pico projectors. Even the Casios - the first hybrid projectors (laser and LED) had some laser related effect. If this BenQ projector has anything like that, it isn't visible under casual viewing.
LW61ST Microphone Input
It's always nice to have the option of plugging in a wired or wireless microphone into a projector to take advantage when a projector has some decent speakers that can easily carry a decent sized training or classroom. This BenQ offers just that, a Mic input.
