If you’re looking for a monitor for gaming, there’s usually nothing to worry about as most high refresh rate gaming monitors have low input lag as well as a quick response time speed.įor non-gaming purposes, reasonably high input lag isn’t much of an issue since you won’t be able to notice it in everyday use. Although some may be more sensitive to high input lag than others, lower is always better. A simple definition for input lag is the delay it takes between pushing a button and seeing the result on the screen. When looking for a TV for console gaming, it’s of utmost importance to check whether it has this feature. Many TVs thus offer a dedicated picture preset, usually called ‘Game Mode’ which bypasses certain image processing to decrease input lag. Since TVs over-process the frames, they have higher input lag than monitors. Response time is measured as the speed at which pixels change from one shade into another, which occurs after the frame is processed. Input lag shouldn’t be confused with the response time speed, which is specified by monitor manufacturers but not by TV companies. However, neither TV nor monitor manufacturers state the input lag in the display specifications, which is why doing detailed research before getting a new display is highly recommended. This also includes all the processing of the image, such as scaling/upconverting, HDR, frame interpolation, deinterlacing, etc.Īs you might expect, the amount of input lag is vital for competitive gaming where every millisecond counts. This is because, they did not factor in issues such as user input delays that may be caused by the virtual desktop itself, and not by the applications running. Input or display lag is the time (measured in milliseconds) it takes for a TV or monitor to react and display the commands you’ve inputted via a device such as a keyboard, a controller, or a mouse. FID is one of three Core Web Vitals metrics (the other two being Largest Contentful Paint and Cumulative Layout Shift) that are part of Google page experience signals. This is an essential aspect of gaming, where an input lag of 16ms or less is preferred on a 60Hz display. First Input Delay (FID) is a user-centric metric used by Google to measure the interactivity (load responsiveness) of a website. Input lag (or display lag) is the delay between your GPU sending a frame to your monitor and the monitor actually displaying that frame.
