Windows 10: How to apply the OPM certificate of display driver?

Hello, I wrote an indirect display driver based on the sample code of IddSampleDrvier. I want to implement the output protection manager OPM function. In the structure of IDD_CX_CLIENT_CONFIG, there is a callback function EvtIddCxMonitorOpmGetCertificate, it corresponds to DxgkddiOpmGetCertificate callback function. I notice the driver should return the display driver's OPM certificate, but I don't know what's this certificate and how to apply this OPM certificate? Could someone show me the way to get the OPM certificate?Kind Regards.Tristan

Custom Driver : Intel HD Graphics & ATI Combo (Alpha) - by nIGHTmAYOR

according to laptop support page they do list an old downloadable driver for intel for windows 7 , weather this is related to there being several variants of that laptop or this laptop has switchable graphics i may just suggest you reset the bios and see if things change , if yes you may be able to apply step 2 , if not then apply step 4 and call it today , you are still better off being on the high performance gpu .

Out of curiosity can you take a snap shot from Settings > System > Display. Scroll down and click the “Graphics Settings” ?
