The best way to output camera to external monitors

Hello everyone, im new to unreal engine, and my first priority is to know the proper way to assing an output from a virutal or cinema camera to an external monitor, i´ve manage to make it work, but the colors i see in the monitor arent the same i see in my viewport, and the process is quite complicated. so, i dont actually know if there is a topic like this hanging arround this place, but i´d like to start a conversation about this topic, so we can understand diferent ways of outputing live signal from our virtual or cinema cameras to an external monitor
