I am trying to analyze DP data for a specific resolution/timing and for that need to updated the on board EDID. How do you do it? Is it possible to do it from Gprobe software?
Install the application then use the wizard setup to configure the EDID. At the end of the operation you will need to click on WriteEDID to finish it. Once you complete this, the EDID will be updated with the new one specified by you.
