Maybe the hardware or firmware can't handle a 48 Gbps signal without errors. That might be why it's limited to 40 Gbps by default. The thing is, this happens even at 40gbps as soon as we apply the modified EDID. If we revert to the original EDID, still running at the same resolution and lane speed, the errors stop. I see only 2 bytes were changed from the original EDID, I am not sure if byte 0xC6 (increment of +0x10 compared to the original) is only the FRL (are they using a bitmask? I assume byte 0xFF is a parity byte, are you sure it's properly calculated ? (I assume so, since the additional 0x10 from the modified byte is subtracted from the parity byte so it seems to be a sum) I never looked into modifying EDID by hand before. |
