PROS / The LG PH550 has an excellent selection of connectivity standards.
CONS / No microSD slot makes it difficult to display home movies or images.
VERDICT / The LG PH550's strong features make it a versatile projector for home and business users.
Home-theater enthusiasts or users in need of a versatile mini portable projector option will find lots to like with the LG PH550. On the outside, the PH550 is slightly bulkier than standard mini projectors with dimensions of 6.9 x 4.3 x 1.7 inches and a weight of 1.4 pounds. Still, it's much easier to carry around than a standard full-sized projector, and the included carrying pouch is a useful accessory when you're on the go. More importantly, the LG makes the most of its slightly larger size.
Throughout its body, the LG includes a deep bench of port options. Along with standards like HDMI input and support for USB storage and composite video, the PH550 touts Bluetooth audio output and even a coaxial connector, meaning that you can hook up an antenna for over-the-air broadcast television. The versatility of the projector is also well supplemented with the LG's full-sized remote.
Unlike most mini portable projectors, which feature equally small-scale remotes, the LG's remote is virtually identical to the ones used on home televisions. As a result, it's far easier to scroll through menus and adjust image settings without having to manually click through individual prompts with the projector's manual controls.
The lack of microSD support is the only major downside to the LG's connectivity options. Considering how common the format is for devices like digital cameras, it's a baffling omission and a nuisance if you want to share content like home videos or photos through the mini projector.
The LG was a relatively consistent performer in our tests. Its marks in our brightness evaluations were slightly below average for the LED-based projectors we reviewed, but its color accuracy is comparable to that of competing models. Color accuracy is the degree to which a projector can properly reproduce individual colors. In practice, the LG's image quality was average, but it was still usable in light and dark viewing environments. With its respectable battery life of one hour and 35 minutes, the projector has the endurance to last through a movie or presentation.
The LG PH550 isn't the smallest mini projector but is still compact and makes the most of its size. While it lacks a microSD slot and its image quality is a small step behind the best mini projectors, stellar features and a full suite of entertainment-friendly connectivity options make it a versatile projector.
