The primary advantage of enabling display control is cutting power usage. Once configured, the RevelDigital players will power off the attached display when not scheduled to play anything. Keeping your displays powered off during off-peak or closed hours has the potential for substantial savings in power usage and increased longevity of your displays.
A few other interesting things you could do..
- Adjust display brightness based on time of day
- Adjust volume based on content, display proximity, etc
- Switching display input to live TV, or coax for certain periods of time
