Are you talking about video as in a DVD player or a streaming device? Depending on your remote, there should be a button labeled "TV/Video", "Source", or "Input". You press that button multiple times to go through the options. Now, your TV may not actually have an input labled "Video". You will probably have choices of different kinds of inputs labeled "TV" or "Antenna", "Cable", or types of ports, such as HDMI1, HDMI2, HDMI3. As you press the "Source" button to go through the sources just pause a few seconds (or you may have to press OK or Select) to watch each HDMI port to see which one your DVD is connected to. I hope this helps. Sorry, but there are many possible variations from TV to TV and different remotes.
