Just giggled as my last meme mentioned trouble with displays and appropriately, a large chunk of the replies were “well MY displays work just fine!” (And charmingly, many were thoughts of things to check, other distros etc. It’s a very kind community, though that may also be the fediverse.)
Yes.
I’m always nervous about those little black-box mysterybadapters, but I have used them and had them be fine.
I don’t really know enough about how HDMI works to say if it helps as much as native DisplayPort at both ends.
I suspect it might help, since some DRM will fail open when it can’t negotiate a restriction. And I imagine those dongles require keeping things simple.
My use of the adapted setup has been rare - mostly due to not having many such adapters on hand when I’m setting things up.
Anyway, I feel a little bad passing on my superstition; but it seems to have helped me.
Worth a shot, I guess.
