... But modern graphics cards don't send composite sync pulses on the pixel lines, they all use separate TTL wires for those. So, the -0.3 to 0.7 and 0 to 0.7 EDID values are functionally identical in practice, as long as your EDID also tells the sender that "Separate" sync signals are supported. Which these EDIDs all do.
