SYNOPSIS
       intel_infoframes [OPTIONS]

DESCRIPTION
       intel_infoframes is a tool to view and change the HDMI InfoFrames sent
       by the GPU. Its main purpose is to be used as a debugging tool. In some
       cases (e.g., when changing modes) the Kernel will undo the changes made
       by this tool.

       Descriptions of the InfoFrame fields can be found on the HDMI and
       CEA-861 specifications.

LIMITATIONS
       Not all HDMI monitors respect the InfoFrames sent to them. Only GEN 4
       or newer hardware is supported yet.
