Official VRR verification tool from Intel

[ywangtw]

Hello video/graphics experts,

Is there an official VRR (variable refresh rate) verification tool from Intel, for displays and convertors?

Or, what should I do to to verify if VRR is actually working with Intel GPU with VRR enabled?

Thank you!

I don't know of a tool. If VRR is offered for activation in the Intel Arc Control software, it will then be executed. The option is grayed out if the device chain cannot provide the function.

Which devices, including the cables, are you using?

My company designs a DisplayPort to HDMI convertor with VRR. We typically connect the convertor to a DisplayPort source with typical DP cable and then to an HDMI display with a typical HDMI cable.  I am wondering how to officially verify the VRR is working with Intel GPU, other than Intel Arc Control software? Thank you!

As a company, you will likely need to follow the tools defined by the Video Electronics Standards Association (VESA) as appropriate to validate your DisplayPort interface for compliance and certification regarding Adaptive Sync.
