I’ve an older Apple show that I’m attempting to get most decision on from my Dell XPS 13. The show is related to the XPS (which helps very excessive resolutions as effectively) by way of an Apple proprietary field that converts the sign to thunderbolt.

When related to a MacBook I can get extremely excessive decision, maximizing the show (so I do know that it’s potential). Once I join my xps, it reveals up as a generic monitor and I am unable to get an honest decision from it.

I’ve tried to activate unsupported resolutions for the show, however I’ve already chosen the very best accessible within the record.

I may have sworn that I had this working some time again, however for the lifetime of me, I am unable to keep in mind how I did it.
