A little more information would help. Settings, HDMI or component. Gaming device - Wii or PS3 for examples. Type of blu-ray player. Most importantly what blu-ray movies. Some are much better then others in regards to video quality. I am sure someone will respond if you can give us more to respond to. Thanks.
