I'm trying to use my 1-HDMI port TV with a set top cable box and a fire stick. I have run a HDMI cable output port on the set top box to Input 1 on a HDMI switch. I have run a HDMI cable from the TV to the HDMI output on the HDMI switch. The fire stick is run to HDMI switch inut 2. If I use input 1, I can only get 1 channel on TV; I cannot switch channels. Do I need to do something different?
