Connecting MacBook Pro 13" to Sony Bravia 40"
Hardware and Software environment:
- MacBook Pro: 13" i5 Thunderbolt/DVI, early 2011, running OSX Lion 10.7.1
- Sony Bravia: 40" LED with ex520 panel. Four HDMI-in ports with one 3.5mm Audio-in port for HDMI
Accessories used:
- mini DVI to HDMI connector: DVI male, HDMI female
- HDMI to HDMI cable: both male
- 3.5mm stereo audio cable: both male
Hardware setup:
[Turn off Bravia while you do the cable fiddling and connections.]
1. Connect DVI male into the Thunderbolt port of MBP
2. Connect one end of the HDMI port with the DVI connector's female, and the other end to any of the HDMI-in ports of Bravia
3. Connect one end of 3.5mm audio cable MBP's headphone jack, and the other end to the audio-in port for HDMI found at the back of Bravia. (The back panel has a proper indication mentioned for this port. Other way of figuring this out is to look for a female pin that is of plastic and is not shiny like other metal plated component input pins etc.)
Software settings:
1. On MBP: Go to System Preferences > Displays and check "Show displays in menu bar"
2. On MBP: Go to System Preferences > Sound and check "Show volume in menu bar" if not already checked. Keep this window open
3. On Bravia, navigate to Home > Settings > Sound and scroll down to "HDMI/DVI Audio Source". Choose "PC Audio" as the option.
4. Next, scroll to "Speakers" and ensure "TV Speakers" is selected. Also ensure that Bravia is not on mute.
Video:
5. Power on Bravia. Navigate to the HDMI port where the MBP has been connected.
6. The "handshake" between the two devices is typically a brief blue screen on MBP, and OSX Lion's Andromeda Galaxy wallpaper being displayed on Bravia. [It is really as simple as this.]
7. In case your see different results on the screens, click on the monitor icon on MBP menu bar. "Sony TV" should be an item group on the list, with 1080p and other resolution options. If not, try to go through the above connection steps once again.
8. Now, Start playing a video clip on MBP and drag the window beyond the right-hand edge of your screen. You should see the window creeping on the Bravia screen. Pull it all the way on to the Bravia screen. This is the MBP's "TV Desktop". [Check the other relevant posts on this forum for Mirroring, Camshell mode, etc.]
Audio:
9. On MBP, remove the 3.5mm audio cable from the headphone jack. Use headphones or external speakers to check if the sound is playing from the video clip.
10. Insert the 3.5mm audio cable back into the headphone jack. On the menu bar, you may notice some change in volume levels when you insert the cable.
11. On MBP, again go to the "System Preferences" window for "Sound". Navigate to the "Output" tab. The default and selected option should be "Headphone". You should also see "Sony TV" as one of the listed devices with "HDMI" as its device type. Select "Sony TV" on this list.
12. Viola! You may notice the volume control on the menu bar being grayed out, and now the sound should be from Bravia speakers which you can control with your TV remote.
