Field notes
A timing panel evaluates the last 720 frames, comparing measured browser output with the display’s target cadence and marking late frames red. The blur explanation gives a pixel-based rule of thumb and notes that strobe or black-frame modes shorten the displayed trail. The page also distinguishes this hold-effect lag from additional delay introduced by games and monitors.
