I have a Roku Ultra with voice remote. I get this message for about 10 seconds every time I turn on the TV: is this input connected to your PC. The message bar won't let you click the button that says don't show this message again. Any ideas?
That's a message from your TV, not from Roku. It sounds as though your TV is defaulting to an input that it thinks is a PC. Whether or not that can be configured -- a default input, and labeling the inputs -- would depend on your TV.
