That's not "has invalid EDID", that's "really doesn't have EDID at all". Might be DisplayID! Any chance you can try a patch like this and give me the dmesg? It'll still look like an EDID failure but it should be something more interesting than cc cc cc cc ... diff --git a/drivers/gpu/drm/drm_edid.c b/drivers/gpu/drm/drm_edid.c index bd74b3f..16beed2 100644 --- a/drivers/gpu/drm/drm_edid.c +++ b/drivers/gpu/drm/drm_edid.c @@ -201,7 +201,7 @@ bool drm_edid_is_valid(struct edid *edid) } EXPORT_SYMBOL(drm_edid_is_valid); -#define DDC_ADDR 0x50 +#define DDC_ADDR 0x52 #define DDC_SEGMENT_ADDR 0x30 /** * Get EDID information via I2C. - ajax
