Best monitor that gives best visual



What makes you go with LG and not the other ones?
 


Could you dumb that down a bit. I don't really understand.
 
The LG do not use low LED PWM Dimming frequencies that ruin motion clarity and cause some people to suffer from health issues like head aches and eyestrain. Read here for further details, as well as the side effects: http://www.tftcentral.co.uk/articles/pulse_width_modulation.htm

As far as the perceived black depth is concearned, check this bias lighting article in order to understand more. In short, in a light background the colors look more vibrant than in a dark one, so the inner black bezels and the glossy black bezels reduce the perceived black depth compared to the matte bezels. Bias lighting can fix this though.
