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.
As of January 2026, we use the Alienware AW2525HM as standard monitor in our research labs.
