Roku stick hdmi switch.
With thousands of available channels to choose from.
The same trick applies the other way around.
When using an avr or hdmi switch you can try to connect your roku directly to the smart tv.
Should this fail to yield results hook up roku to your monitor and play the problematic stream.
Then use the switch to control which device gets connected to the tv.
Connect your cable box and roku to inputs on the switch and run the output of the switch to an hdmi port on the tv.
That is if you have several inputs into an hdmi switch that autoswitches to the active input this roku will interfere with it and the autoswitch won t properly work.
If this doesn t help check if the roku and the connection or cables work on another tv.
This roku device always puts out a signal that interferes with an hdmi autoswitch feature if you want this as an input to the switch.
