We use high-quality keyboards and mice for gamers via a USB distribution. That allows the customer to try out the demo mode for lighting and haptics in order to select "his" device
Computer monitors can be supplied with similar images via HDMI distribution. So the customer has the opportunity to find the best device for him in a fair comparison. In addition, (via a source up to 4K @ 60Hz incl. HDR, e.g.) Test images, Gamedemos but also graphics, texts and tables are recorded, in order to respond to the customer's needs. A service worthwhile!
