The vast majority of projectors cannot rival televisions in resolution, but LG's new battery-powered LED devices have TVs beat on another point — portability. Where most projectors need to be installed at the back of a room, LG's new PH450U ultra-short throw (UST) projectors, are capable of projecting images from distances of just 33 centimeters on any flat surface of up to 2 meters wide. Their small size and battery power also means they can be moved around a room, or even carried around outside.
With a rechargeable battery that will last two-and-a-half hours and an LED lamp with a brightness of 450 lumens, the PH450U should be ideal to watch a full length movie outdoors.
The main downside of the device, as with most projectors, is the resolution. The PH450U can produce a 200cm image from just over a foot away on a wall, but it is stuck at 1280 x 720, a resolution that is still HD, which may seem too fuzzy for people increasingly used to 4K TVs. Still, you are not going to be able to lug your 150cm 4K screen on your next camping trip without some advance planning, whereas LG's new projector could just slip into your bag. The PH450U will be available for around $650 starting in October.
