Display lag

<p>Display lag is a <a href="/facts/Phenomenon/4CBrlVeW">phenomenon</a> associated with most types of <a href="/facts/Liquid_crystal_display/8B6xGBEz">liquid crystal displays</a> (LCDs) like smartphones and computers and nearly all types of <a href="/facts/High-definition_television/AuE6FRFI">high-definition televisions</a> (HDTVs). It refers to <a href="/facts/Latency_(engineering)/6Bjhn30H">latency</a>, or <a href="/facts/Lag_(video_games)/kb0QfGzX">lag</a> between when the <a href="/facts/Signal_(electronics)/41YqUJ8c">signal</a> is sent to the display and when the display starts to show that signal. This lag time has been measured as high as 68 ms, or the equivalent of 3-4 frames on a 60 <a href="/facts/Hz/6Wshj5qm">Hz</a> display. Display lag is not to be confused with <a href="/facts/Pixel_response_time/3kQrmztQ">pixel response time</a>, which is the amount of time it takes for a pixel to change from one brightness value to another. Currently the majority of manufacturers quote the pixel response time, but neglect to report display lag.
