How to Connect MacBook Pro to Sony Bravia TV

I have recently bought Sony Bravia KDL-40EX500, and my challenge was to connect my MacBook Pro and use it as an external monitor. Is it easy? Yep, all you need is:

- Mini DVI to HDMI adapter (I bought this on monoprice.com)
- HDMI cable
- 3.5 mm stero cable male to male

Now, look for PC/HDMI slot which is behind the LCD TV and audio in which is just above the HDMI slot, see picture (Click to enlarge)

Plugin the cables, and get your MacBook Pro and connect the cables, see pictures:

Now for the TV to work as external monitor, you have to make some changes in the settings, by default when you connect the TV it is considered as second monitor by MacBook Pro. So go to System Preferences > Click on Display and select mirror option, by doing this the display on your MacBook Pro and Sony TV will be same. Now if you close the lid of MacBook Pro, it will go to sleep, to avoid this you have to connect a mouse, key board and plug-in the power adapter. Close the lid and click any key on the keyboard or click the mouse, that's it you are done. Now you can enjoy watching movies from your MacBook Pro on Sony Bravia. Hope you liked the post.
