AAXA P4 Pico Projector

Marc Davidson, January 20, 2012


No zoom. As with most pocket projectors, the P4 lacks a zoom lens, so the only way to adjust image size is to move the projector.

Unreliable remote. The P4 comes with a remote, but it didn't work reliably in my tests. You can't really count this as a serious problem, however, since most pocket projectors don't come with remotes. Also, the optional wireless keyboard and mouse serves as a highly reliable alternative.

Barely usable audio. As with most pocket projectors, the P4's built-in audio, with its 1-watt speaker, is hardly worth having. Count on plugging in a headset or external powered speakers if you want sound.


The AAXA P4 gets points for its portability and features that enhance that portability. Most obviously, its ability to read files from memory, so you don't have to lug along an image source, can make it a lot more portable in practice than a smaller, lighter projector without that feature.

The P4 also offers some welcome touches that make it easy to setup. It's a lot easier to focus than most pico projectors, with a thumbwheel that has just the right level of resistance to let you control it easily. And like many pocket projectors, it comes with a tripod you can use to adjust the height and make it easier to point up or down to whatever you're using for a screen.

Granting that the AAXA P4 would be a more compelling choice if it fully lived up to its promise -- letting you use its full resolution for external sources in particular -- it still offers enough the way it is to qualify as impressive. Keep in mind too that many, if not most, projectors in this category offer only 640x480 native resolution, the same resolution the P4 drops to for external sources. That makes this a shortcoming only in context of the projector's own widescreen resolution. And it's hard to complain too much about issues that wouldn't be limitations if an extra feature weren't there to begin with.

In any case, the P4 stands out for both its high level of image quality and for its balance of image quality, brightness, features, and price. Taken together, that's easily enough to make it well worth considering as is. And it's attractiveness will increase dramatically with the promised firmware upgrade that will let you take better advantage of its full resolution.

Where can I purchase this device, and not the P4-X? The website itself only sells the P4-X and other websites will say P4, but actually be selling you the P4-X. The P4 has the windows ce software, whereas the newer P4-X does not. Please advise.

Bought this product, and it for like a year. I am currently a college student who lives in messy and cluttered dorms, and I found this projector extremely useful. I use it for entertainment, and I can literally bring it everywhere.

Found a solution to the resolution problem for Mac OS X. Using switchResX, you need to create a custom display with the following settings: 1056x600, 60.000 Hz. (Note the 60.000 Hz, if you use 60.3Hz you'll get a vertical band on the screen where the color is off, causing glowing pink faces.) You then select the 800x600 option in the sources menu.
