When installing lag testing software, make sure the program is compatible with your graphics card driver.

Assuming your graphics card driver is compatible, this software streamlines the process of obtaining input lag measurements. Some lag testing methods use software called SMTT.

This makes them useful for comparisons between different gaming monitors, but less useful for finding out the total real-world latency of a system. These devices can only measure the display lag intrinsic to the monitor, however. This method involves using an external device with a light sensor that sends a simple video signal to your display screen via HDMI cable and then records the time between sending the signal and the light sensor registering the output. Input lag measurements, in milliseconds, can be derived from the total latency minus the specified response time. You can do this a few ways, but essentially the principle of these lag testing methods is the same: a high-speed camera connected to your input device, recording the total time between initiating a signal and the image appearing on the display screen. To test for display lag, you’ll need to test the total latency of the system.

Monitor and Smart TV manufacturers usually include pixel response time in their specifications, but they rarely list a figure for total input lag. Consult your monitor warranty or computer insurance as well if the problem keeps recurring or gets worse and can’t be resolved on your own. Moreover, you can test for backlight bleed and more with a black uniformity test, a great feature to have that’s often included with the monitor you buy. If you’re slightly handy with electronics, you can make such a device with minimal investment. A number of technical outlets such as Blur Busters employ photodiode or light-sensitive resistor-based input lag testers. You can measure display lag using a dedicated test device such as the Video Signal Input Lag Tester, or you can employ a DIY solution. Minimizing display lag on your top gaming and computer monitor is especially important when playing online multiplayer shooters. Typical input lag, measured in milliseconds, is most often an issue for monitor purposes like fast-paced games and competitive eSports play. How to Fix Input Lag on Monitors: When It Matters Here are some methods for how to test monitor input lag.

You can also use a VGA cable or specialized low latency digital input cables.

To minimize system latency, use game mode if available, make sure you’re using the native resolution, and set the frame rate to equal the monitor’s refresh rate.
