SVGA Budget Classroom Projector Review
May need cables and a cover. The only cables the PDG-DSU30 comes with are a power cord and VGA cable. If you want to take advantage of the video or audio ports, you'll have to buy cables separately. Similarly, it doesn't include a case or protective cover. If you want carry it with you or store it with some minimal protection, you'll have to buy a case or cover as well.
No built-in control panel. Aside from a power button, there are no controls on the projector, which means there's no way to adjust settings if you lose the remote. Sanyo says that if you place an order before noon Pacific Time, it will normally ship a $35 replacement remote the same day.
Low volume. The 2-watt mono speaker in the PDG-DSU30 is loud enough for a small conference room, but isn't even close to being loud enough for a medium or large classroom. If you need audio, you'll need a separate sound system.
No remote mouse control. One potential issue is the lack of any way to control a PC's mouse through the projector's remote. If you need to page through a presentation or use the mouse cursor as a pointer, you'll have to stay close to your computer to use your computer's keyboard and mouse.
Rainbow artifacts. Because of the way single-chip DLP projectors create colors -- showing each primary color in sequence, and leaving it to the human visual system to integrate the colors over time - sequential color breakup is a potential issue for any DLP projector. When you move your eye or an object moves on screen, light areas surrounded by dark colors can break up into little rainbows, because each color falls on a different part of your retina.
Some people see this rainbow effect easily and others never see it. It's obvious enough with the PDG-DSU30 that anyone who is at all sensitive to the effect will certainly see it. Those people may find the projector annoying to watch for long sessions -- as with a full length movie, for example. However, it shouldn't be an issue for shorter sessions.
Long turn off time: One strike against the projector's portability is its turn off time. The projector needs about 120 seconds after you turn it off to cool down enough to go to standby mode, so you can unplug it and move it safely. Two minutes can seem like a long time if you're in a rush to get somewhere or someone else is waiting to use the room you're in.
Despite a few shortcomings -- notably the long turn off time and the possibility of having to do without the projector if you lose the remote -- the PDG-DSU30's strong points easily trump the potential issues. The easy setup, combined with a reasonably high quality image that is bright enough to stand up to typical classroom or office lighting, is enough to earn it a recommendation. The 3-year warranty helps make it a better value. Finally, the power saving features should be particularly welcome in a classroom situation, where it's far too easy to leave the projector running when you leave a room.
