I saw somewhere that several LCDs were connected to a single PC - not by video cards but by using LAN cables and a device like a modem or router. The LCDs were used to display different videos from the PC. I checked the LCDs but I didn't find any network ports on them; there was another device next to each LCD that connected them to the PC.
Does anyone knows what this might be and how to create one?
If so, how can I access these monitors in my C# application?
