Projectors used to be huge great devices that hungrily sucked up energy and air and dominated coffee tables while the projectionist dominated the after-dinner conversation regaling guests with tales of their recent holiday adventures.

Digital projectors are often still quite large, but one welcome development is a huge drop-off in pricing. ViewSonic’s new PJD5 Series low profile DLP projectors start at just £249 plus VAT. Designed to be hooked up to a games console or a laptop, the device supports 120Hz playback, making it ideal for 3D viewing. If you aren’t ready to buy a 3D TV, this could therefore be a good value alternative.

The PJD5223 can accept inputs from a Sky 3D box, 3D Blu-ray players such as the Philips BDP7600, or a Sony PlayStation 3 via its HDMI connector. Content can also be played from external hard drives. To enjoy 3D playback with the projector, ViewSonic 3D glasses or compatible nVidia 3D glasses are required.

The 2.6kg ViewSonic PJD5223 kicks out 2700 Ansi lumens of brightness and produces an image of between 27in and 300in from a distance of 1.2 to 11 metres. It would be equally at home in a small office environment or a classroom. It offers a contrast ratio of 3000:1 and has a lamp life of 5000-6000 hours (standard and eco modes). Image support runs to 24bits and 16.7 million colours. The ViewSonic PJD5223 projector offers XGA (1024x768-pixel) native resolution support. Other models in the PJD5 Series offer WXGA support.

Models cost from £299 inc VAT. For full details see
