The picture quality is generally fine too, with images brightly resolved and extremely well focused. The only small niggles were a slight fall-off in brightness in the top corners of the picture and, at the lowest level of zoom, some outward bowing at the sides and top of the picture.
Perhaps more disappointing, though, especially given that this projector will see a lot of service in poky meeting rooms and small offices, is the fact that it has a relatively long minimum throw. In fact the shortest distance the LP120 can be positioned away from a wall or screen is 1.5m; we’ve seen much larger projectors that can do better than this and it reduces the projector’s all-round flexibility.
The incredibly small size of the LP120 also, inevitably, limits the number and variety of connections available. In fact there are only three ports, all crammed on one end of the projector: an S-Video socket, a 3.5mm audio input, and what InFocus calls an M1-DA port. This basically an extended DVI port: in this case the supplied video cable splits in two, terminating in D-SUB and USB connectors. The latter enables you to use your remote to navigate your slideshows without having to reach for the mouse.
What the M1-DA port also enables LP120 owners to do is use wireless technology to help out with projections. InFocus supplied our LP120 with one of its LiteShow modules. You plug it in, install the LiteShow software on your wireless-equipped laptop and, hey presto, you can carry out presentations without having to connect the two with a bulky video cable.
Handily, the software will install onto a USB memory key too, so you don’t have to reinstall the software every time you want to use the projector with a different laptop.
There are limitations to this type of connection, however. The LiteShow module uses the 802.11b standard for connections, which limits the bandwidth to 11Mbits/sec, which means there’s no chance of using it for projecting video.
It’s also a very expensive option at a whopping £320 extra, so even for those who have had enough of faffing around at the beginning of a meeting plugging cables in and arranging themselves close to the projector, it’s unlikely to prove an enticing addition.
If it’s the ultimate in portability you’re after, then there really isn’t anything out there that comes close to the LP120. Its size and weight means that it can quite comfortably be carried around in one bag along with a medium-sized laptop without putting too much strain on your poor old shoulder.
Understandably InFocus has had to make some performance compromises to squeeze everything into such a small package, such as a lack of brightness and an array of connections that could hardly be called generous. And you’re unlikely to want to go for the wireless option at a hefty £320 premium.
But for this projector’s target market – the mobile professional who doesn’t want to have to develop a body-builder’s physique just to get from meeting to meeting – these are limitations that can quite comfortably be lived with, especially when you consider that without the LiteShow wireless module, this projector can be picked up for less than £1,300.
