Which is a good thing, compared to my sony SDM-X52, which in digital
mode only supports the native resolution, but the EDID erroneously
reports the mode supported by the digital connection in both case.

The EDID should report only the supported (native) mode, and the chip,
knowing what it can scale or not, should handle the other cases, no ?
