Display lag contributes to the overall latency in the interface chain of the user's inputs (mouse, keyboard, etc.) to the graphics card to the monitor. Depending on the monitor, display lag times between 10-68 ms have been measured. However, the effects of the delay on the user depend on each user's own sensitivity to it.
This could involve changing or reducing input device use, improving a user interface to reduce stress, speeding up a process to reduce the time a user needs to be at the computer, etc. An example of a tool that changes the impact would be speech recognition. Speech recognition replaces keyboard (and sometimes mouse) input with vocal input.
The monitor keeps displaying the currently received image until a new frame is presented to the video card's frame buffer then transmission of the new image starts immediately. This simple mechanism provides low monitor latency and a smooth, virtually stutter-free viewing experience, with reduced implementation complexity for the timing ...
Input lag or input latency is the amount of time that passes between sending an electrical signal and the occurrence of a corresponding action.. In video games the term is often used to describe any latency between input and the game engine, monitor, or any other part of the signal chain reacting to that input, though all contributions of input lag are cumulative.
[citation needed] The lower one's ping is, the lower the latency is and the less lag the player will experience. High ping and low ping are commonly used terms in online gaming, where high ping refers to a ping that causes a severe amount of lag; while any level of ping may cause lag, severe lag is usually indicated by a ping of over 100 ms.

Pie menus, which delay appearance until the pointer is not moving, reduce intrusiveness to the same level as mouse gestures for experienced users. Pie menus take up more screen space than linear menus, and the number of slices in an individual menu must be kept low for effectiveness by using submenus.

Deinterlacing techniques require complex processing and thus can introduce a delay into the video feed. While not generally noticeable, this can result in the display of older video games lagging behind controller input. Many TVs thus have a "game mode" in which minimal processing is done in order to maximize speed at the expense of image quality.
