As explained earlier, faster refresh rate monitors should take less time to display a new image, but it doesn't always mean they have low input lag. The screen can't change its state instantly, and the amount of time it will take depends on the technology and components of the display. This is the step where the video processor sends the image to the screen. Once the monitor has processed the image, it's ready to be displayed on the screen. One of these settings that could add delay is variable refresh rate, but most modern monitors are good enough that the lag doesn't increase much. Most picture settings won't affect the input lag, but it's only a few image processing settings that are rare on monitors anyways. Although you can't control the processor speed, you can control how many operations it needs to do by enabling and disabling settings. The time this step takes is affected by the speed of the video processor and the total amount of processing.

Scaling it (like 720p to 1080p, or 1080p to UHD), but this is more common on TVs.

Adjusting the frame rate, like using motion interpolation or judder-removal, but it's very rare on monitors.

Adding overlays (like custom crosshairs).Once the image is in a format that the video's processor understands, it will apply at least some processing to alter the image somehow.

Bluetooth connections especially add latency, so if you want the lowest latency possible in the video acquisition phase, you should use a wired mouse or keyboard or get something wireless with very low latency. However, some devices like wireless mice or keyboards may add delay. This has never really been an issue with PCs since previous analog signals were virtually instant, and current digital interfaces like DisplayPort and HDMI have next to no inherent latency. The more time it takes for the monitor to receive the source image, the more input lag there'll be. Three main functions delay the monitor: acquiring the source image, processing it, and displaying it. The total input lag time is the addition of three parts

The input lag test stops counting the time when the pixels first change color on the screen, and it doesn't wait for the full transition, which includes the response time measurement. Learn more about response time here. Even though our response time test consists of squares transitioning between different gray slides, similar to the white square flashing on the screen in the input lag test, the two aren't the same. Input lag is the amount of time it takes for the monitor to display the received signal, but the response time is the time it takes for pixels to change from one color to the next. Some people may confuse the input lag test with the response time. Below is a table of the minimum input lag for the common refresh rates on monitors. Any 144Hz monitor has a minimum input lag of 3.47 ms, so even if we measure an input lag of 4 ms, it's only 0.53 ms higher than the minimum, which is fantastic.

It means that if a monitor has a refresh rate of 144Hz or 144 times per second, then a new image appears every 6.94 ms, but if we're calculating the input lag at the center, it only takes 3.47 ms for the white square to appear. Since monitors refresh the screen progressively from top to bottom, any new image reaches the center of the screen in the middle of the refresh rate cycle. We place the photodiode tool in the middle of the screen so it reads the flashing white square when it's displayed in the middle.
