I have multiple Roku Smart TV’s. The ONN Roku TV, the Hisense Roku TV, and the Samsung 6 Series. I also have older model dumb TV’s and monitors.
I am looking to mirror the image from the internal Roku Smart TV’s onto another TV in the same room. Is there a way to force one of the HDMI ports to be an output instead of an input?
I do not have the option to use a separate Roku or other device at this time. I specifically want to loop the smart TV image to an additional monitor.
