How to Connect a MacBook Pro to a Samsung TV (5 Steps)

Examine the backside of your Samsung TV to find which display ports are available. Apple produces Mini DisplayPort adapters that are compatible with DVI, HDMI --- with a third-party adapter --- and VGA cables, so you'll want to see which port type your TV has in common. HDMI ports are semi-rectangular, while VGA ports are rhombus-shaped with several rows of pins. DVI ports feature a grid with multiple female pinholes.
Plug the rhombus-shaped end of the corresponding Mini DisplayPort adapter into your MacBook Pro. The DVI, HDMI and VGA Mini DisplayPort adapters all feature the same functionality, so which type you use ultimately comes down to personal preference.
Plug one end of the corresponding display cable into the other side of the Mini DisplayPort adapter.
Connect the other end of the display cable into the appropriate port on the Samsung TV.
Turn on both devices, if you haven't yet done so. Set the TV's TV/Video settings to the corresponding mode --- HDMI if you're connected via HDMI, for instance --- to begin using the MacBook Pro on the TV.
