Check your current setup to see what you are working with. If you currently have your PS3 plugged into a high-definition television using an HDMI cable, you are already getting the best Blu-ray experience you can. If not, continue.
Upgrade your current television to a high-definition television. You'll need a TV that supports a 1080p resolution to get the sharpest picture possible. You can take your pick from Plasma, LCD or LED TV's or even consider a 3d HDTV to play 3D Blu-rays.
Connect your PS3 to your new high-def TV using a High-Definition Multimedia Interface (HDMI) cable. This is the only cable type as of publication that can provide a full quality Blu-ray experience.
