Maybe they are too cheap and don't properly connect the ddc wires or pull the
right pins down.  Can you confirm that they actually work with windows or
different hardware?  If they do work, can you attach the same logs but with
debugging enabled?  (add drm.debug=0xff to the kernel command line in grub)
