All models come with an analog and digital DVI input; according to the model, perform the touch connection via USB. According to the area of application choose between the particularly long-wearing resistive 5-wire touch technology, the acoustic surface wave technology (SAW) or the projected capacitive multi-touch technology (PCAP) with a bezel-free surface. All SAW and PCAP models feature an impact and scratch-resistant glass surface, which optimally guarantee them protection from damage – even and especially in public usage areas. The stable stand allows for maximum flexibility, as it is easily adjustable horizontally up to 90°. The menu buttons are located on the side, and may be locked to protect the monitors from unauthorized access, or for cleaning purposes. Even the touch function may be easily switched off temporarily for cleaning.
