Optoma PK320 Projector – Physical Tour1

Optoma PK320 Lens Throw

The Pico PK320 projector can fill a 16:9 60″ diagonal screen from about 4 feet 1 inch.  Note Optoma says 150″ diagonal at over 10 feet, but that’s really pushing your luck with a 100 lumen projector, even in a pitch dark room.

The projector can be used for very small projection as well, such as projecting a 10 or 15 or perhaps 20 inch image (far larger than, the screen of an iPhone or even an iPad) which makes it a light weight device for viewing photos  and other content from portable devices.  The projector can create an image from as close as 5 inches (8 inches diagonal).

Lens Shift & Setup

No lens shift.The image must be aligned by physically moving the projector. Focus is done by rotating the lens once you have achieved your desired image size.

Working the focus is a bit tricky, only because the ring is so small and a tiny movement does a lot.

Although there is no lens shift for keeping the image correctly rectangular as the projector projects at an upward or downward angle, the projector does offer keystone correction (as virtually all projectors do), which can be adjusted from the control panel (up and down arrows), the menus, or the remote control.  While technically keystone usage adds a touch of softness, it’s in line with this projector’s resolution and abilities.  The PK320 is not the sharpest projector around, but it is typical of pico projectors with the same SVGA resolution.
