With the BenQ MP522 ST you can go and show just about anywhere in the world. It can handle power from 100 to 240 V AC at 50 or 60 Hz. (Optional alternative power cord may be required.)
Its OSD (on screen display) can be switched between English, French, German, Italian, Spanish, Russian, Traditional Chinese, Simplified Chinese, Japanese, Korean, Swedish, Dutch, Turkish, Czech, Portuguese, Thai and Polish.
And the MP522 ST can process and display video signals in NTSC (the North American TV standard), NTSC 4.43, PAL, PAL-N, PAL-M, PAL-60, SECAM and more than a dozen PC and Mac resolutions. Of course if your programming source provides closed captioning this projector can process and display modes CC1, CC2, CC3 and CC4.
But the MP522 ST has virtues beyond its flexibility. Economical mode lowers fan noise to below that of a whispered conversation and extends bulb life by a third. Auto Off saves money too. A built in FAQ button projects answers to frequently asked questions right on the screen. And Wall Color Correction corrects the color when you don't have a screen and have to project on to a painted wall or blackboard.
In short, if you can find a place on earth where the MP522 ST won't get the job done, just bring a sharp stick and draw pictures in the dirt (or icepack) to give your presentation.
