EDID/DisplayID Writer

[surfacedockguy]

Thanks for this tool. I was able to correct a checksum error on one of my DisplayPort monitor simulator dongles that I use for testing hubs and docking stations.

The Synaptics VMM6210 MST chipset inside one of my docking stations did NOT like the checksum error and refused to sync up to the dongle. Once the EDID was corrected, it worked fine.


Now I'll try to edit the EDID to have some more resolutions


Can you explain the 256 byte driver limitation? It is because of one of the Microsoft APIS not allowing a larger payload? Is it plausible to write more than 256 in Linux?
And any chance of releasing this tool open source?
