Didn’t think you wanted duplicate content in your forums, so I’ll just link to the OP which has gone unanswered in the Mac forum.
Thank you!
Roku only supports 1280x720 for photos (1080p for video). The Roku 4 does have 4k support, but that is currently limited to video only. It is on out list to investigate handling better resolution on the Roku 4, but all other models cannot support anything higher.
Thank you!
