Epson has caused quite a stir at CEDIA Expo with the launch of its Pro Cinema LS10000 and LS9600e 3LCD projectors with reflective laser technology.

The LS10000 is a 4K model, while the LS9600e is a wireless 1080p projector. Both use a laser light source to deliver "unprecedented Absolute Black contrast ratio and one of the industry's largest colour gamuts," says Epson.

The 4K unit can project images with up to 1500 Lumens of colour brightness and the same for white brightness, while the Full HD one delivers 1300 Lumens.

Advantages of the laser light source are said to be rapid warm-up and cool down, high-speed contrast control for bright and dark scenes, and up to 30,000 hours of use. The 'Instant On/Off' function means pictures appear on screen or shut down with virtually no wait, says Epson.

Bright 3D Drive is designed for greater brightness when viewing 3D content, and both projectors can handle Full HD 1080p in 2D and 3D.

Operation is said to be "whisper quiet", and on the LS9600e a WirelessHD transmitter connects up to five HDMI devices simultaneously. It also has MHL connectivity to display content from compatible smartphones and tablets.

Both models have 2.1 x power zoom, power focus, lens shift up to 90 per cent vertical and 40 per cent horizontal, as well as a lens position memory that can store up to 10 settings for 16:9 or 4:3 projection areas.

Epson says its new Pro Cinema projectors will be available in the US this autumn for prices "below $8000".

Also new from Epson are three 3LCD Full HD/3D projectors: the Home Cinema 3600e ($1999), Home Cinema 3500 ($1699) and Home Cinema 3000 ($1299).
