I built the latest git version of edid-decode, and I see it printing this info: Extended tag: video capability data block YCbCr quantization: No Data (0) RGB quantization: No Data (0) If I toggle that "RGB quantization" bit (if I can figure out which byte it is in :-) will that be the magic that induces the intel driver to use full range RGB all the time?
