Input lag

Input lag
Input lag (or display lag) is the delay between your GPU sending a frame to your monitor and the monitor actually displaying that frame. This is an essential aspect of gaming, where an input lag of 15ms or less is preferred.

Input or display lag is the time (measured in milliseconds) it takes for a TV or monitor to react and display your commands you’ve inputted via a device such as a keyboard, a controller, or a mouse.

This also includes all the processing of the image, such as scaling/upconverting, HDR, frame interpolation, deinterlacing, etc.

As you might expect, the amount of input lag is vital for competitive gaming where every millisecond counts.
