Q: how activation display multiples in macbook pro 13

Hi pattyufita,

Depending on what model of MacBook Pro you have, you will need the correct adapter for its video out port. Also, the other end of the adapter would need to fit whatever video in port your TV has. So for example the most recent MacBook Pro has Thunderbolt for video out and your TV might use HDMI video. See the specifications on this page for the MacBook Pro -

Of course you will need to find the specifications for your own model of MacBook Pro. You can find out which model you have by going to the Apple menu and selecting About this Mac and clicking the More Info button.

Thanks for using Apple Support Communities.

Best,
