The main disadvantage is the viewing angles, the real viewing angle, without distortion, is 50-60 degrees. The same trouble was in the LG LA644V series, a 39-inch matrix LG bought from the Chinese and the same drawback was traced there. I don’t know what’s wrong with this TV: RGBW technology or LG buy this matrix from the Chinese, but the viewing angles do not match the declared ones, a step to the side and the picture becomes dull. Below is a photo and a link to a video where you can see the viewing angles.
