LG has unveiled what it claims is a world first - a 3D 1080p single-lens projector - at the Consumer Electronics Show in Las Vegas.

The CF3D pumps out 2500 ANSI-lumens and has a contrast ratio of 7000:1. It runs at 120Hz in standard mode, which is then split into two 60Hz signals during 3D usage. It packs auto-picture-calibration tech alongside HDMI upscaling and dual engine output. It has two HDMI 1.3 ports, along with a USB input. There's a 0.61-inch SXRD, and ISFccc. 

At the same time, the company also announced a more portable option - the HX300G. This projector uses an LED light source for power efficiency and lamp life, but outputs just 300 ANSI-lumens, so you'll need to close the curtains before you'll see much of a picture.

It weighs 1.7 pounds, and supports a variety of content formats including Microsoft Office docs, DivX video, MP3 audio and JPEG images. It has USB connectivity and an XGA resolution alongside a wireless FM transmitter and contrast ratio of 2000:1.

Pricing and availability haven't yet been announced, but you can be sure that the 3D option won't come cheap. We'll let you know as soon as we hear more.
