They say the combination gives you a better picture, but its the energy savings that are really impressive.
The folks at Acer have a first on the way. It's called the K750, and it's the first projector to combine laser and LED technologies for its light source. Acer says that you'll get better color saturation to 85% of NTSC thanks to the system of three independant sources. You'll also find a 100,000:1 contrast ratio and 1,500 lumens brightness.
The more tauted stat, however, is the energy savings that comes with this combo. Not only will you get 20,000 hours from the hazardous substance free lighting, but the projector offers an ExtremeECO mode that gives you an energy savings as high as 90%.
The K750 hits the UK this month of a price around $2,650. There's not yet word on a US release.
