@Gobinaath bro,
thanks for your Pic, It seems u have a good quality pic on your TV..
But I would like to know the Contrast Ratio...which is like 500000:1 in my sony LED. that means, Black/Dark image will be 500000 times Darker than the White/Light image on my sony LED. means, Contrast ratio, put simply, is the difference between the brightest a TV can be, and the darkest.
If u see, many TV has very low contrast ratio means u will see a gray image than the perfect black on that TV.
