Have got a 37LDZ80 for son's room won a AARTON-LCD 1111 mount a year ago on another forum , question is the 4 screws for connecting the 2 mount brackets to TV would need to be screwed in about an inch is this okay? don't want to screw in to far and damage TV but obviously the mounts need to solid on TV . Anyone any experience of how far they normally go in..
