PROPixx MRI/MEG

1440 Hz projector

The PROPixx is a unique DLP LED projector which has been designed to be the most flexible display possible for vision research. The PROPixx features a native resolution of 1920 x 1080, and can be driven with refresh rates up to 480 Hz in RGB mode (1440 Hz greyscale) with deterministic timing. The PROPixx uses high brightness LEDs as a light source, giving a larger color gamut, better stability and much longer lifetime than halogen light sources (60,000 hrs vs 2,000 hrs).

Our 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.

In addition, the PROPixx includes an array of peripherals which often need to be synchronized to video during an experiment, including 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/O to video refresh with microsecond precision. The PROPixx is available with multiple projection lens options including long-throw lenses for MRI and MEG applications.

Combine the PROPixx with the TRACKPixx 2kHz binocular eye tracker, and experience the simplicity of a single clock timebase for all your data!

Lens Calculation

Screen size vs throw distance The Throw distance is the distance measured from the front of the projector to the screen. This is an important consideration when it comes to projector installation as it determines whether or not you have enough room to install your projector with the desired screen size, and if your image will be the right size for your screen.
