Instructions
Turn on your television and PS3. Once loaded, click on "Settings" and then "System Update."
Select update 3.530, which includes the 3-D software update. You can also select and download any other updates that may be waiting for you as well.
Click on "Settings" once the update is complete. If you don't wait until the updates are complete, the next steps won't work.
Click on "Display Settings" then "Video Output Settings." Allow the PS3 to search for your television. This should only take a few seconds. Once PS3 has found your TV, it will tell you its compatibility level, including 3-D compatibility. Adjust the size of the television on the PS3 screen, if necessary.
Insert a 3-D Blu-Ray disc or a 3-D game into the PS3. Put on your 3-D glasses and press "Play" to watch in 3-D.
