The W5000 and W20000 both feature BenQ's Senseye technology, Texas Instruments’ 1080p DLP DMD chipset, and a HQV high-performance video processor.

That gives the W20000 a contrast ratio of 20000:1, while the W5000 offers 10000:1.

According to BenQ, both offer true cinematic full 1080p HD experience and perform seamlessly with a wide range of devices – from conventional VCR players (remember them?) to the latest HD-DVD (remember them?) or Blu-ray players.

“The projectors enhance image contrast via their Dual Iris technology, so that bright images become brighter and dark images become darker,” read a statement from BenQ projected onto a wall.

BenQ said the second level of Iris control – provided by DynamicBlack technology and Texas Instruments – enhances contrast based on the exact image being shown.

“DynamicBlack digitally examines source video to determine the appropriate iris aperture for the level of light present in a given scene and opens and closes the projector iris accordingly,” a statement said.

“Built to deliver ultra-high contrast, both projectors allow consumers to see visuals on-screen just as they would see them in real life.”

The projectors both feature four viewing modes: Cinema, Dynamic, Standard, and Photo.

They also support multiple video formats, including 480p, 576p, 720p, 1080i and 1080p.

The BenQ W20000 sells for £2,499 including VAT and the W5000 will set you back £1,399 including VAT, with both available in the UK from today).
