At 60 Hz a frame takes 16.7 ms to send. A display that shows each line as it arrives, so the bars read progressively later down the screen. With 0.0 ms of extra processing, the Leo Bodnar top, middle and bottom bars read 2.8, 8.3 and 13.9 ms.
A model of the Leo Bodnar tester's three bars: each reads the time from the start of the frame to light appearing at that height. The three bar heights and the 'extra processing' value are illustrative; blanking time is ignored. Reviewers conventionally quote the middle bar.
