Send DDC/CI commands to Thinkreality A3 glasses

Hi Lenovo/Qualcomm,

Is it possible to control Thinkreality A3 micro displays with DDC/CI commands?

Can the glasses handle 60 or 90 DDC/CI commands per second?



This is not something we've tried. I will reach out to Lenovo and see what they say about this.

Hi Ron,

I noticed Lenovo's recent announcement of the new  T1 Glasses.

On further examination I discovered that T1 supports Screen Anchor Mode that allows to anchor 2D display into position independent of head rotation. - search pdf for "anchor"

This feature appears to be independent of SDK or any apps/settings/software running on the host PC/Phone. This means that you could anchor a BIOS screen of your laptop/PC.

Processing of 2D screen shifting/zooming is done entirely by the glasses.

Unity/Unreal or OpenXR are not involved.

Is it possible to find out how this is achieved independent of SDK?

Are there plans to make this feature available to other XR1/XR2 glasses or headsets?
