Internal Memory: The PK320 provides 2 GB of internal memory which is plenty for most Microsoft Office presentations. The right side of the image was slightly brighter than the right. Our sample unit's brightness uniformity was a respectable 78%, or about normal for this class of projector.

Note that Bright and Movie mode brightness levels are not available in battery operation as you must use the AC adapter to achieve the brightest picture. It put up 87 lumens in Bright mode, 78 lumens in Movie mode, 40 lumens in Standard mode, and 23 lumens in Eco mode. Unlike most picos, the PK320 exhibits no rainbow artifacts at all.īrightness and Uniformity: Like many projectors, the PK320 fell a bit short of its 100-lumen specification. Like most pico projectors, the PK320 uses LED illumination. Flesh tones in video images are good, but shadow detail and highlights are somewhat limited by the PK320's 1,000:1 contrast ratio. Data images have adequate contrast, and photos are lifelike. Image Quality: For such a small projector, the PK320 does very well in putting up saturated and evenly balanced color. That had little effect on movie viewing where a soft focus can actually improve the look of the image, but small text was hard to decipher at larger than a 40-inch diagonal. Beyond that point, the image began to blur slightly. Clear focus could be achieved out to a projection distance of about 65 inches which produced an image diagonal of about 40 inches. The PK320 is specified with a projection distance range of 8-235 inches which corresponds to an image diagonal of 5-150 inches, but the optical system of our test unit did not function well over that entire range. Getting used to what the icons control takes some practice, but it is an efficient method for getting to the functions available on the PK320 once you have some experience using the remote. But those same icons can also do source selection and data transfers from your computer. You can get to a traditional (though limited) display menu that allows tweaking of brightness, contrast, sharpness, and gamma settings. Rather than the usual array of pushbuttons, the remote has a set of seven icons that perform different functions depending on the mode you are in.
The first thing you will notice when turning on the PK320 is that the remote control looks unconventional. As a DLP-based projector, there is virtually no maintenance required for the PK320 although an occasional vacuuming of the air intake vents is always a good idea. Since the illumination source is a set of LEDs with a rated life of over 20,000 hours, you will be getting a new projector before you ever have to think about replacing the LEDs. The PK320 comes with a one-year warranty on the projector and a 90-day warranty on the battery. Of course, at 100 lumens and lower, ambient light must be controlled for an acceptable image, but with small groups and an image in the 40" range, performance is very good for a half-pound projector. An optional larger battery extends projection times and can provide 100-lumen output for about two hours. The AC adapter must be used for 100-lumen output. The PK320 has a rechargeable battery that is specified to last for about 45 minutes in Standard mode and 90 minutes in Eco mode, but it can only put out 50 and 25 lumens, respectively. Unlike most of its competitors, the PK320 has a built-in Microsoft Office compatible viewer that handles Word and Excel files without file conversion.
And if you store your images in the projector's internal memory or have them on a USB memory stick, you won't have to haul your computer along to display them. Its 854x480 native resolution works well for both widescreen movies and standard 4:3 presentation material.
It is small, light, and full-featured with a street price of about $425. If you make small group presentations and do not need the brightness of a full-size projector, the Optoma PK320 is a new 100-lumen pico projector that should interest you.
