AFAICT, yes, this last one. For asymmetric cloning, a misfeature exceeded in stupidity only by panning. Because you have a panel with a bizarre size and then an external that's sane, and you try to clone, and even though the bizarre size would fit it's not available on both mode lists. And at _that_ point, this isn't an EDID parser issue at all, it's driver policy. - ajax
