Some Quick Fixes to Input Lag

Before we conclude with our discussion, let’s have a look at some of the easiest ways of reducing input lag in your monitors and TVs as well:

Firstly, in the case of TVs, you can switch to game mode while gaming. Other than that, you can disable motion smoothing as well, which could help reduce the overall input latency.

Apart from that, in the case of gaming monitors, you can turn off power saving options, or lower the resolution to the point where it gets aligned with the overall settings of the display. Apart from that, turning off picture enhancing or altering features can also be beneficial in this regard.


  • What causes input lag?

    First and foremost, input lag is something unavoidable because it is a natural part of every device. This is for the reason that all the electric or digital devices require some time to respond to the input being given.

    Having said that, in monitors, a few major reasons that cause input lag are as follows: the time taken up by chips to process digital signals, adjustment of color contrast and saturation, and the proper sizing of images.

  • What is the acceptable input lag for gaming?

  • Does FPS decrease input lag?

    Without any doubt, increasing FPS can have a vivid impact on the input lag. So much so, that input lag can be decreased to the level of acceptance by increasing the frames per second rate.

    In addition to that, with more FPS, you can not only have low input lag but also the overall graphics experience gets enhanced, as there is a much faster refresh rate and less delay in processing the input.

Final Thoughts

Here comes the final point of what is input lag and how does it impact the overall performance. By now, you must have learned that input lag is a usual and natural aspect of any device. However, they are different in every other device or type of monitor.
