Before I purchase a camera, what specs should I be looking for if I want to make sure it can be easily connected to a TV or computer screen for real-time copy of the camera LCD display?
I have seen that some cameras feature an HDMI port, but is that what I want? Are there other options?
Note: I'm not asking for how to do it with a given model, as suggested by the duplicate question. Instead, I want to know about the generic ways to do this and the various specifications I should be looking for.
