PROPixx User Manual
System Overview
The PROPixx is a unique DLP LED projector designed to be the most flexible display possible for vision research. It
features a native resolution of 1920 x 1080 and can be driven with refresh rates up to 500 Hz (RGB mode) or 1440 Hz
(Greyscale mode) with deterministic timing.
The PROPixx uses high brightness LEDs as a light source, giving a larger color gamut and much longer lifetime than
halogen light sources (60,000 hrs vs 2,000 hrs). The LEDs also support high bit depth and high frequency full color
stimulation which would not be possible with a color-wheel/halogen architecture. For stereo vision applications, our
high speed circular polarizer can project stereoscopic stimuli for passive polarizing glasses at up to 400 Hz.
The PROPixx comes equipped with an array of peripherals which often need to be synchronized to video during an
experiment. These peripherals include a stereo audio stimulator, a button box port for precise reaction-time
measurement, triggers for electrophysiology and eye-tracking equipment, and even a complete analog I/O subsystem.
You can now successfully synchronize all of your subject I/Os to video refresh with microsecond precision.
The PROPixx is available with multiple projection lens options including short-throw lenses for CRT replacement
applications, and long-throw lenses for MRI/MEG applications.
The PROPixx system is made up of two distinct components; the controller and the projector unit.
