Hi, you can play Blu-Ray through it via an external Blu-Ray player, however if it is HD ready, you will get 1080i performance not 1080p, (not such a bad thing on a set of that size ). I am sure you will not be disappointed with the outcome.
The TV I bought is HD Ready, has Freeview and also an inbuilt DVD player. Instead of spending more money and buying a separate Blu ray player, do you think the inbuilt DVD player will play blu ray discs?
