Optoma knows of two about projectors, so it’s no surprise that the PK301 is not only small and lightweight but made with the same quality as its bigger siblings. These pico is pumping a relatively bright image, and we appreciate the convenient focusing. However, keep the PK301 relatively high price compared with LG Optimus 3D price and short battery life is back. And we must overcome some hurdles, see PowerPoints.
The Optoma PK301 looks like one of the companies was larger projectors in the dryer too long. The rectangular device measures 4.7 x 2.7 x 1.2 inches and weighs only 8 ounces. It’s all black to save for the chrome ring around the lens focus, and the sides are vertical slats allow the air in.
On the back of the device are the inputs of its 24-pin universal connector, HDMI, audio output, A / V, Micro-USB and power. On the right is a microSD card slot, and the bottom is the battery and a tripod mount. The PK301 comes with a padded bag.
The PK301 is also bundled with an adapter cable that connects the universal port with VGA. A 2.5mm-to-component connector and a USB cable. Unfortunately, the included documentation – is poor compared to the 160-page, 16-language booklet that comes with the Samsung SP-H03 projector – a simple folding brochure.
At the top of the PK301 is a four-way button navigation pad with two buttons for menu and input source. The all-black keys would be impossible to use them were not illuminated in blue. The PK301 is on-screen selections are easy to understand – the main menu you can switch between RAM (settings), microSD, USB, and select Search – but it is simple compared to the SamsungSP-H03. Also, the menu background becomes black, and it seems like the image is still cut off, the alarming is the first time you use.
While Pico projectors will never rival full-size projectors regarding brightness, we found the rated 50 lumens of the PK-301 to be much more appropriate in a darkened room. The brightness can also be rotated up to 20 lumens in standard mode. Although its native resolution is 854 x 480 pixels, the PK301 able to take pictures with up to 1080i project. It supports 3GP, AVI, MOV and MPEG-4 video formats and BMP, and JPEG photos.
We found the focus ring to be highly accurate. It was the right amount of stiffness, so we do not attempt to force him into position, and did not feel it would drift out of focus. But we want an anti-keystone feature, giving those in PK301 not to be projected onto the same plane as the image.
At 3 meters from a screen, the projector is a 23-inch diagonal image, slightly less than the 28 inches we saw with the Samsung SP-H03 beamed. Nevertheless, the images were bright and crisp: the discoverer of a 720p via VGA clip was played from our notebook wonderfully lively and supple. As with any pico-projector, you want to dim the lights. However, we found the PK301 to be brighter than the SP-H03 when it projected images against a wall lit by the sun; we could pull it over one or two feet further back. However, if we played a 1080i version of The Departed from a Micro SD card into the projector, the playback was choppy.
Also, unlike the SamsungSP-H03 and the MPro150 3M can not natively PK301 view PowerPoint presentations, you first need the projector to a notebook via USB and install the ArcSoft Media Converter 3 software, which is on the projector itself. To view a PowerPoint, you must drag and drop files into the Media Converter 3 app, which will then transfer the presentation to the projector. Also, note that this software converts static images lose the present, you will not have animation and sound.
While projector companies are usually in their claims, the PK301 declared battery life of 1 hour (in 20-lumen mode) was very close to hyperbolic accurate, the battery dies after 56 minutes of constantly playing a movie. However, took the Samsung SP-H03-battery 40 minutes longer. Optoma sells an extended battery pack that it claims offers more than 5 hours of play time. The PK301 is covered by a one-year parts and labour warranty.
There are some things we PK301 on the Optoma, Pico-projectors of all we’ve recently tested, it is the easiest and most accurate focus, and it has a good number of connection options. Its pictures are is pretty bright too. However, we prefer the Samsung SP-H03, which is less expensive, longer battery life and can natively display has power points.
