ipad retna won't mirror to my TV using cable A1438

Hi A lot of the cables no longer work maybe due to copyright The best thing you can do is buy an Apple Tv then you can Mirror anything from your iPhone / Ipad they cost £59:00 Cheers Brian

I would take your ipad and cable to an apple store. Try in store. Heard some cable are replaced at store. Else try new cable at store and get one the works. Changes were made in 8.x that prevented older cables from working.
