I am in a need of connecting a PC monitor using 8051. Here the purpose is to connect a monitor additional to the PC monitor so that it can display same as on the master monitor. Is it possible? Any one can suggest a way to connect a monitor without additional VGA card? Expecting your valuable suggestions and opinions. Please Help me.
You could use a microcontroller and some display controller to make a monitor/tablet like device with Ethernet support and run some kind of VNC like application. So you're basically building a thin-client.
Or use an Ethernet/IP based KVM switch to display stuff remotely but you'll still need a videocard in the PC to connect to the KVM switch.
