Well I've made a couple threads on here detailing some topics on a business I'm trying to create and I'm now approaching another problem. I currently want to use games as a live display to showcase my establishment in the form of projections on the side of a building. Essentially I want to be able to have a display that rotates through everyone who is playing games, giving anyone that is watching from the outside a 15-30 second glimpse of someone actually playing a game. Currently I don't know of something that is streamlined to do this.
An obvious, but totally obtrusive and unmanageable option would be to run a HDMI cable from the second display port on all the computers to a massive KVM and have someone manually toggle the display. Ideally if this could be done virtually without interruption to the person playing games it would be amazing. Adding to that if it could detect if a 3D output is currently being rendered on the screen (they're in game) so it could skip computers without any display that are in sleep or someone who is sitting on the desktop and automatically rotate between users that are gaming, although I sorta doubt there is anything like that.
Anyone have any ideas or have already done something similar to this?
