XGA DLP Microportable Projector
Image quality. Beyond features and convenience, a great data projector needs to deliver a great picture. The HX300G does this in spades. Brightness uniformity is such that there are no obvious bright or dim areas of the image, which reduces distraction when viewing plain text documents. There is no noticeable screen door effect, even when sitting very close to the screen; in fact, it can be hard to see the inter-pixel gap at all. In Cinema mode, colors jump off the screen (photography and data graphics are best viewed in this mode). While it lacks the brightness of larger projectors, the HX300G does not suffer in terms of image quality - unless you turn the lights on, of course.
Lamp life. The LED light source is rated at 30,000 hours of life. That's 8 hours of presentation time every day, five days a week, for about 15 years. In practical terms, the light source will long outlive the projector.
Connectivity. For such a small projector, the HX300G has an impressive array of connections. The most notable is the HDMI port, allowing the use of high-quality digital video with no fuss. There's also a standard VGA port for laptop and desktop computers. Composite video and 1/8" audio in and out round out the connection panel. Finally, the projector has a USB port, used for the display of files from USB memory devices.
Onboard speakers. The HX300G has a pair of 1W speakers, giving it true stereo sound. The maximum volume is, as one might expect, rather lackluster, but for small audiences of 5-10 people in a quiet room it will perform well enough. Using maximum volume can cause distortion, but around 70-80% volume the fidelity is maintained.
FM Transmitter. The HX300G has a unique FM radio transmitter, allowing you to "broadcast" sound to any external system with an FM receiver. Range is quite short, and you'll get a lot of static if the receiver's FM antenna is more than about three meters distant, but this is a novel feature that has the potential to revolutionize portable and presentation projectors. If possible, it is still preferable to use a hard-wired connection by running a 1/8" audio cable between the projector/signal source and the external speakers. In cases where this is not possible, though, having the FM transmitter as a backup option is appreciated.
Media player. It is becoming more common to see small projectors with the ability to display video, photo, and data documents from USB flash media without the aid of a computer. In essence, the projector itself becomes the signal source, requiring nothing but a power connection. The HX300G has such a media player onboard. We tested the projector with several file types, including common Microsoft Office documents (that's right, it can display Powerpoint presentations), and the projector was able to display everything we threw at it without a single hitch. Photo slideshows are slower than they would be on a computer, due to the processing power required to load and display large image files, but otherwise we did not encounter any problems. If you are a traveling businessperson who needs to display either image files or Microsoft Office documents, the HX300G will let you do it without a computer at all. That can drastically reduce the amount of gear you have to haul around with you.
Portability. The HX300G is built for mobile presentation, with a compact, lightweight form factor. The case measures a scant 2.4" x 6.3" x 5.3" and the projector itself weighs only 1.7 pounds, not including the power brick. With onboard media player functionality and an included carrying case, in many cases you can simply load your presentation materials on to a USB flash drive and skip the computer entirely.
Audible noise. The HX300G is very quiet despite its relatively high lumen output. At full power, fan noise is audible, but can be easily spoken over without requiring that you raise your voice. Using the reduced power modes correspondingly reduces audible noise, with Low lamp mode dropping audible noise to near imperceptibility.
