Description: This article contains some of the most frequently asked questions regarding input lag from monitors and TVs in Winter 2019.

Q: What is input lag?
A: Input lag is the delay between an action you take, such as moving your mouse or clicking a key on the keyboard, and the system registering and displaying that action. Input lag is measured in milliseconds or the acronym ms.

Q: When should I be concerned about input lag?
A: Input lag matters most in competitive gaming and when performing actions that require precise timing or quick reactions. With high input lag, the window to perform an action may pass before the system registers your reaction.

Q: Where can I find information on the input lag or a display?
A: Input lag is rarely listed in manufacturer specs. The best source of information for most products will be third party reviews.

Q: Can input lag be modified on a display?
A: There are settings you can adjust that may improve input lag such as:

• Decreasing resolution and increasing your framerate can improve monitor performance
• Disabling any power saving features and enabling Game Mode can improve the performance of a TV

Q: Is input lag the same as response time?
A: No, input lag is not the same as response time. Response time is how the monitor changes from black to white or gray to gray pixels, where a lower response time will reduce the phenomenon of ghosting on the screen which can be best described as smearing or blurring pixels on a display.
