VIEWPixx

New display toolbox optimized for the needs of vision researchers

The VIEWPixx is a complete display toolbox which has been conceived specifically to replace CRTs in vision science labs. The VIEWPixx features high-performance industrial LCD glass and a panel controller designed specifically to support vision research. Our innovative LED backlight design features superior display uniformity, and a wide color gamut exceeding that of any CRT.  The VIEWPixx also includes an array of peripherals which often need to be synchronized to video during an experiment.  The VIEWPixx also includes an array of peripherals which often need to be synchronized to video during an experiment. These include a stereo audio stimulator, a button box port for precise reaction-time measurement, triggers for electrophysiology equipment, and even a complete analog I/O subsystem.

Because we implemented the video controller and peripheral control on the same circuit board, you can now successfully synchronize all of your subject I/O to video refresh with microsecond precision.

As with all VPixx Technologies products, the VIEWPixx is field upgradable. If you need a new feature in order to follow some exciting new direction in your research, we can develop the functionality in our labs, then email you an update for your VIEWPixx.
