CECTray is for my Pulse-Eight HDMI adapter. My Playfield doesn't come on and off by itself so I use this device that send "power-on" commands to the TV upon Windows startup. This app runs once in the background at startup.
For my buttons, I'm using an iPac-2.
Monitors are left to right ...PF (ID2), BG (ID1), LCD DMD (ID3).
