many DLP projectors can do this. My Digital Projections'
Titan unit has a menu option where I can bring in digital
shutters from four sides. It accomplishes this by turning
off the micromirrors for the pixels that aren't desired.
Very effective. I just wish they gave me DMX control of
this parameter so I can change it easily during a show.</blockquote>

controlled via ethernet or serial port? If so, it wouldn't be
difficult to rig up a DMX-to-Ethernet/Serial converter using a
Raspberry Pi or BeagleBone Black running Open Lighting

If you are referring to the IRIS shutters, the only things I have
seen adjustable is the shutter speed, and n real way to partial open
or close and hold them. <br>
