Monitor latency, also known as input lag, is the delay between the source of the input (keyboard, mouse, controller) and the display of the image on a monitor or a TV. In other words, it is the time it takes from when a GPU sends a signal to the monitor, for the monitor to display that frame.
The input lag is measured in milliseconds, but how quickly your frames refresh makes a huge difference in gaming, especially in multiplayer and competitive. It can be the difference between getting killed and getting a kill.
What is an acceptable monitor latency?
If you’re gaming, the lower your monitor latency, the better. The ideal is always zero, but since that’s seldom the case, here is a rough guide as to what you’d consider an acceptable monitor latency.
As previously mentioned, the input lag is measured in milliseconds.
- 0 – 20 ms is excellent. The input from the keyboard/mouse/controller to the times the frames refresh will be instantaneous. As we previously discussed, this is extremely important to gamers, especially in competitive settings and e-sports. For a gaming environment in general, 10ms is considered ideal, and anything less than that is a bonus.
- 21 – 40 ms is good. A good range that facilitates online gaming without hindering experience or impacting the score. The skill will come into play, but if you’re playing a game where every second counts and reaction times are important, you might get outplayed by someone with a smaller input lag, such as a pro gamer.
- 41 – 70 ms is average. This is still within acceptable lag parameters, assuming this is the only lag that’s being experienced. A lag caused by anything else as well, such as the network, may impact your gaming experience, and you may notice the slight delay from when you click a mouse or push a button to when the action on screen occurs. It’s worth mentioning that even at 50ms, the gamers can still have an enjoyable game.
- > 70 ms is bad. Anything above 70 ms is undesirable and would diminish the gaming experience, especially if you’re playing online with friends or competing. If you’ve ever wondered “How did I shoot first, but died”, you may want to check your set up for input lag/monitor latency. If the lag rises to 100ms and over it will make a game unplayable and if it goes into 170 ms, it will cause the game to fail altogether.
With the surge in popularity of online multiplayer games, many casual and upcoming gamers are starting to pay a lot more attention to the input lag. While connection, ping and state of a game’s servers are generally the main culprits for lag, those with impeccable connections can still suffer monitor latency.
Monitors are an important part of a gaming set up, and not just for visual quality. The better the games get, the more demanding the hardware to run the games will be. Monitor set up is not negligible if you’re a serious or a hardcore gamer, however even if you’re just getting into gaming, starting out with the best possible monitor, with the lowest possible latency is preferable.
