I would like to ask some questions from you, I need you your help.
Thanks a lot.
We have a lot of monitors was placed each garage. We need to know the status of monitors, so we try to develop an app, the app automatic to get the status of monitor.
Project system information:
Platform: Microsoft windows 7 x64
Video card: W600
Monitors: 1X6 monitor wall
Can we get the status of monitor by W600 video card? What about the SDK?
Do you know how to do? Or, idea?
I am looking forward to your answer.
you can have a look at the ADL SDK: http://developer.amd.com/tools-and-sdks/graphics-development/display-library-adl-sdk/
ADL gives you the possibility to get some state information on the connection status, e.g. if a monitor is connected via DisplayPort, DVI or using a dongle. You can have a look at the functions: ADL_Adapter_ConnectionState_Get and ADL_Adapter_ConnectionData_Get.
As far as I know you cannot check a monitor state like "power on" or "power off" since as soon as the monitor is powered off the connection is no longer present. If you know that a monitor is connected to a specific port you could check the connection status and if it shows up as not connected it implies that the monitor must be powered off.
