The picture quality of this TV is just amazing. When I go to friends houses and see their TV screens compared to the Samsung it is a noticeable difference. Quality is crisp and sharp. The colors are vivid If you calibrate this TV right, you will never look at another brand of TV ever again. The built in speakers are not the greatest; however, I do not use them due to having home theater sound system installed. So the quality of the built in speakers did not bother me.
