Optoma has launched three corporate projectors, the EH470, EH461 and EH460ST which feature FullHD native resolution and produce brightness of up to 5000 lumens. The difference is in the lens which provide 1.5x zoom, 1.2x zoom or short throw 0.5:1.
As well as the usual dual HDMI + MHL, VGA and composite inputs, presentations can be plugged in from a USB device and played via the projector’s built-in OfficeViewer media player without the need for a laptop or PC. This also supports Excel, Word, PDF and JPEG files.
All models have four corner geometric adjustment. The EH460ST includes a short throw lens for a 100 inch image on a screen or wall from just over a metre away.
Full support is provided for Crestron, Extron, AMX, PJ-Link and Telnet LAN commands, and there are connections for RJ45 and 12V trigger. An audio input can be used to access the internal 10W speaker.
