Hello @Adames0521 

Thank you for contacting Intel Embedded Community.

I looked internally but it seems we don't have an SSC option for HDMI, but I think you can try modifying the available settings with the Discon Tool and the VBT and json files from your device to try to find a fix to your issue.

You can check the document #744003 - Alder Lake Platform VBT File Structure and Tool User Guide.

You will need a Premier account in order to get access to this document and the Discon Tool.
