This 3D display system, exclusive to DLP projectors, is in some ways a sub-division of Active technology. For it’s still based on the idea of embedding the two-frame nature of 3D images into an accelerated frame rate. In 3D-Ready’s case, two 50 or 60Hz 3D frames (one for each eye) are embedded within a 100 or 120Hz frame rate, so that all the DLP projector needs to do is be able to handle such a frame rate.

'DLP-Link' Active shutter glasses

This system depends on active shutter glasses, like full HD Active 3D technology, but these ‘DLP-Link’ glasses are generally cheaper. 3D-Ready projectors tend to be extremely affordable too - often well under £1,000.

3D-ready DLP projectors tend to be good value

The main issues with 3D-Ready technology are that it only works up to a 1280x720 resolution rather than a full HD one, and that it was really designed to suit 3D PC graphics cards more than 3D Blu-ray players.

Optoma's 3D-XL 3D adaptor

Optoma now does a £250 adaptor, the 3D-XL (pictured above), that lets you enjoy the likes of 3D Blu-ray and Sky 3D on 3D-Ready projectors, but there are issues with this as we discovered during our recent review.
