If someone reports something working on a Purism forum or Reddit forum, then I add a link in the table to the forum post where it was reported, so people can ask the original reporter. In this case, see: [MyL5] Librem 5 and HDMI - #10 by Cc281080
However, others have edited the “Tested Accessories” page and they haven’t always identified who did the testing. I think that we should add a “Who Tested” column to the table, so people will know who to contact if they have questions.
