How to measure Display Lag if I don't have 2 screens? Knowing one of the screen's display lag you will know the other screen's display lag too. Screen in the left shows images 9 ms faster than screen in the right. As you can see there is a 9 ms input lag difference. It's the same computer with two 120 Hz screens connected. This image from 3d vision blog shows an input lag measurement. Display lag can be as high as 68 ms and as low as 1 ms.

Most monitor manufacturers do not say how bad is their input lag, professional reviewers end up doing this job. Display lag is the amount of time it takes for a monitor to render an image, this is due to image processing such as motion smoothing, edge smoothing and upscaling. This is one of the most important kinds of Input lags, and often confused with Input lag itself. Buy a better computer or graphcis card.What can you do to get better Frames Per Second? Now let's take this example to the extremes, with 30 FPS you have 33 ms delay and with 240 FPS (and 240 Hz monitor) you have only 4.17 ms. How many frames your CPU/GPU send a second to a display adds to Input lag, for example if you have a 60 Hz monitor coupled with a 60 FPS capable computer, there is going to be sent 60 frames per second, so 1000 milliseconds divided 60 equals 16.67 ms delay. PC’s and consoles are the one in charge of sending the image to display in the first place.

Check your mouse's or controller software configuration to see if the Report rate it is at 1000Hz: Although worrying about having a good mouse is still important because it helps you aim faster and more precisely. This is the most negligible kind of Input lag, it depends on the polling rate of your mouse, a 1000 Hz mouse polling rate means your mouse report it’s position to the computer 1000 times per second, which amount for an almost meaningless 1 ms lag. Types of Input lag (from less to more impactful)

This added to other kinds of input lag makes it not rare seeing 300 ms or 0.3 seconds input lags. Most monitor manufacturers do not advertise this very important number and it takes professional reviewers to reveal it to you, it can be as high as 68 ms. The most mentioned part of this is the “Display lag” and it refers to the time your monitor takes to show the image. Input lag is the time between you press a button and the order appears on screen. Let’s suppose you are the one behind in frames, you could be “in the past” as much as 300 ms (0.3 seconds), which may seem unimportant, but trust me, it is important, to the point of it explaining those “that didn’t hit me” moments or affect your experience making a game unplayable. When playing online games on a computer or console the image you see may not be the same image your opponent sees, either you or your opponent could be some frames ahead or behind, making for an unfair advantage/disadvantage.
