[visionlist] Video Switcher: An economic solution to high grayscale-resolution display

[Xiangrui Li]

Video Switcher bases on the same principle as Pelli-Zhang video attenuator, while it can drive both monochrome and color monitors (analog). A trigger can be used to measure reaction time or synchronize response recording accurately. The design and test results are described in Journal of Neuroscience Methods, 2003, 130(1): 9-18.
New versions have been developed, and the switch between grayscale and color displays can be controlled by software. So it works as if it did not exist!
