The 1-watt stereo speakers are barely loud enough to let you hear everything if you're sitting right next to the projector in a quiet room. One minor issue that the P4-X shares with most small projectors is a nearly useless sound system. Given that I see these artifacts relatively easily, few people, if any, should see them often enough to consider them a problem.

I saw them a bit more often in video, but primarily in a single scene that tends to show them easily. Even with that screen they were so fleeting that I didn't find them bothersome. With data images, the only time I saw the artifacts was with one screen that tends to bring them out. That makes it very much worth mention that the P4-X shows very little rainbow effect. Rainbows and Other IssuesRainbow artifacts, with bright areas breaking up into little red-green-blue rainbows, are always a concern for any single-chip DLP projector.

Skin tones were a little oversaturated in some cases, but video quality was generally good enough to be usable. Neither showed up in any significant way in more carefully lit scenes, which is what you'll usually get with commercial source material. I saw some slight posterization (colors changing suddenly where they should change gradually), and a moderate to major problem with shadow detail (the loss of detail in dark areas), but both showed only in scenes that tend to create problems for most data projectors. Video quality was also surprisingly good. On our standard suite of DisplayMate tests, it delivered fully saturated, eye-catching color good color balance with suitably neutral grays over the entire range from white to black and reasonably crisp, readable text at sizes as small as 9 points. Quite apart from issues of brightness, the P4-X did a good job on data image quality. This closely matches the 48-inch maximum diagonal image size I settled on before I did the calculation.

Based on The Society of Motion Picture and Television Engineers (SMPTE) recommendation for image brightness, an 80-lumen image in theater dark lighting should allow comfortable viewing at screen sizes ranging from 35- to 47-inches diagonally. I tested the P4-X primarily with AC power.

That makes the lower brightness a more than fair trade-off for the P4-X's much lower price. But keep in mind that perception of brightness is logarithmic, so although 300 lumens is 3.75 times 80 lumens, it won't make the image look anywhere near 3.75 times as bright. The only other connector is a stereo audio output for a headset or speakers.Р вЂќР’В«rightness and Image QualityWith palmtop projectors like the Editors' Choice 3M Mobile Projector MP410 ($599 direct, 4 stars) offering 300 lumens, the P4-X's 80 lumens may not sound like a lot.

AAXA also sells additional adaptors (at $12.99 to $19.99 direct each) for iPod, Zune, and PSP connections. A proprietary connector also lets you connect to a computer VGA port using a supplied cable, and an AV port paired with an adapter adds connectors for composite video and stereo audio. If you want to use an external image source, your connection choices include a mini-HDMI port for a computer or video source, which is a particularly nice touch. Note that the only file formats the documentation says the projector can read are AVI, MPG, MP4, and MP3, but in my tests it read JPG and TXT files without problems, and AAXA says it reads GIF and BMP as well. To read files from memory, you can either plug a card into the microSD card slot or take advantage of the mini USB connector and supplied adaptor that lets you plug a USB key into the other end. SetupSetting up the P4-X consists of little more than turning it on, pointing it at whatever you're using for a screen, focusing the image, and then using the built-in menus to pick the right image source. Like many pico and palmtop projectors, the P4-X enhances its portability by letting you read files directly from memory, which in this case means USB memory keys or microSD cards. The good news is that you may not have to carry an image source also. You'll want to take advantage of the higher brightness whenever you can, which means that in addition to the 10-ounce P4-X itself, you'll generally need to carry the power block as well, for a total weight of 15 ounces.
