Instructions
Check your connections. If you have a 3D-enabled TV, the PlayStation 3 must be connected by an HDMI cable to deliver 3D content.
Update your PlayStation 3 firmware. Connect to the Internet on your PlayStation 3. Go to the "System Update" icon in the "Settings" menu. Download firmware updates.
Ensure your 3D settings are correct. The PlayStation 3 should automatically detect your 3D TV's screen size. If you are seeing distortion, go to the "Settings" menu. Select "Display Settings" followed by "Video Output Settings." Scroll down until you see the "3D TV" section to ensure the size is correct.
