The standard lab monitor is the Benq XL2420Z. For support monitors, the Dell Professional P2213 and the Dell Ultrasharp U2312HM are used. For experiments requiring touch-based interaction with the display, an ELO capacitive monitor can be made available.

Calibration
Our Benq XL2429Z lab monitors are individually color-calibrated using a Datacolor Spyder4 Elite colorimeter, based on a fixed hardware profile as specified below. This calibration is used to normalize the color representation of all lab monitors, which allows users to transfer their stimuli from one lab to the other with a minimized change in color perception. The color profile for each monitor will be automatically loaded or refreshed when a user logs into Windows, and will be periodically updated to provide the best possible representation of the ICC standard the monitor's display panel can deliver.

Installation
The color profile should be pre-installed on all lab computers and cannot be changed by the default user. Contact our administrator if you are not sure whether the correct profile is loaded.
KVM Switches
A KVM switch is a hardware device that allows a user to control multiple computers from one or more sets of keyboards, monitors and mice.
