I manually added all the remote codes for the Monprice 4X4 True Matrix HDMI® Powered Switch in my system. I have added the input/output setting to my activites but the remote refuses to change the input/output when I change activities. When I choose the HDMI switch device and press the soft buttons the HDMI switch will change the input/output perfectly every time. Any suggestions on how I can get the switch to change input/output settings in the activities?

The delays are now set at:
Power On Delay: 1500 ms
Inter-key Delay: 1000 ms
Input Delay: 1000 ms
Inter-Device Delay: 500 ms

You need to add the Switch device to all desired activities (Activity Setting > Review the settings for this Activity > Yes, but I want to add more control of options and devices for this Activity). For each reviewed activity, it will ask what input or channel does your Switch need to be on?

Yes you can add the switch as an Amplifier/Audio Video Switch
