The LG PH550 can be used completely without wires due to the Wi-Fi and Bluetooth connection. Its own battery allows the projector to work for 2.5 hours. The PH550 throws a 55-inch image from the 5.5ft distance and can be used for different tasks (movies, presentations, games, etc.).
The LG PH550 review from the standpoint of the design allows seeing that the device is compact (1.7 x 6.9 x 4.3) and lightweight (1.4 pounds), so it’s easy to move it around in a special soft bag. It has a glossy white case and rounded covers; moreover, the unit’s lens is placed in a copper-colored ring. The focus lever can be found right behind the lens and such an element makes it easy to bring the device to a decent focus. The 4-way controller is located on the top, the same as the Power button. Pay attention that the Off switch is on the rear side. The back part also contains the HDMI port, USB Type-A port (suitable for USB thumb drive), AV-in jack (for DVD hooking up), and audio out jack for headphones. Here I also see a slot for Kensington lock (for safety) and VGA port for connecting to a PC.
The LG Minibeam PH550 has a built-in tuner, which makes the device a good substitution for classic TV. Moreover, the resolution of the picture is HD (1280 x 720) and it’s easy to control the channels via the remote. Its rechargeable battery is decent as it takes only 3 hours to recharge it (that’s really fast when compared with other similar models). The audio output can be performed both via wire or Bluetooth. The inbuilt two 1W stereo speakers are enough to hear all the sound details, so there’s no need to purchase additional amplifiers (if the device is used in a mid-sized room). The LG Electronics PH550 accepts HD 3D input, moreover, it can be switched to/from a 3D mode at the request of the user.
The LG Electronics PH550 Minibeam projector boasts 550 lumens, so the picture is bright and clear (even when changing the image size). It has 5 modes for perception convenience (Standard, Sport, Game, Cinema, and Vivid) and almost all of them are pleasant-to-eye (besides the Cinema one, as it provides too bright colors, which can be hardly called natural). There’s a small rainbow effect, but it doesn’t bother the viewer while watching the video or presentation material. The fan noise isn’t perceptible even when the projector works under heavy load. It’s hard to hear its noise from more than 2-3ft away.
