How can I control the display power On/Off from software?

We have a requirement to display video, but need to make sure that the monitor is on and the correct HDMI port is selected as the active display. The Stick should be able to turn on the display, force the active HDMI port to be the one that is connected to the Stick, play some content, and then turn off the display. We are running Windows 10, and our development environment is C# .NET 4.5.

What software support does Intel or anyone else have to get this done?

Hello ScottPKuehn,

At this point the power option will depend on the operating system which is the one that handles the power states, in that case the operating system will be able to wake the monitor from a sleep state, the signal option will depend on the monitor itself it has automatic signal sensing it will select the correct signal input if the monitor does not have these features the compute stick will no be able to order the monitor to turn itself on or off nor select the correct input signal.

Regards,

Amy.

Would it be possible to send CEC commands via the HDMI port to the monitor/TV? CEC does have all the capabilities necessary to meet our requirements.

In regards to your inquiry I escalated the case to our engineering team and according to the information that we received from them the

Intel® Compute Stick does not support HDMI CEC technologies.

Does the new Intel Compute Stick (STK1AW32SC) support HDMI-CEC in hardware? Add on solutions like: https://www.pulse-eight.com/p/104/usb-hdmi-cec-adapter https://www.pulse-eight.com/p/104/usb-hdmi-cec-adapter,

are available but the ideal case would be native support for this technology given the primary use cases for the form factor are likely behind televisions.

Thanks
