I bought a lg 3d tv last month but ever since I bought it, I am fed up with it features, Firstly the picture quality wasn't as it was said to be and also somewhere I do experience flicker while watching Spiderman in 3d. Yesterday I was trying to connect my laptop to it through HDMI port but i wasn't able to. Even If the laptop gets connected,the sound continues to come from laptop only not the TV. I don't know what to do.
