Displays Sony Professional has introduced four business projectors, including its first ever ultra short throw models, the VPL-SX535 and VPL-SW535. It has also launched two installation models - the VPL-CX235 and VPL-CW255. The UST and installation projectors include the ECO Picture Mute function, which reduces power consump- tion by up to 70 per cent. This feature can be used by schools or corporates as an instant off-on button, which means there is no need to turn the projectors completely off.
