1 ms gaming monitor, can you tell the difference? it is necessary?

The response time measures how quickly a pixel can change from white to black or from one gray shadow to another. Therefore, a lower (or faster) response time on a monitor means that its panel can display the frame changes that occur in the image without distortion, without lag, and without indirect adverse effects. However, a response time as low as 1 ms may be “too” low or not noticeable to the naked eye compared to other slower monitors … or not?

The advantages of a 1 ms (or less) monitor

The representation of moving images on the monitor screen is done by changes in pixel colors, which is why response time is extremely important for this. A longer response time can lead to some indirect adverse effects such as ghosting, a kind of trail left by objects when moving around the screen, and it occurs because the pixels are not able to change color (or turn on / off) fast enough.

This obviously affects the homogeneity of the image, reducing distortion, and improving the gaming experience. Now, this is at a technical level where the advantages are more than evident, but the discussion here is whether this is really something that the human eye detects or if with somewhat higher response times the difference is not noticed.

Some users say that it is absolutely imperative that the monitor has 1 ms response time (or even less) to have the best gaming experience, especially in the competitive environment, while many others say that 5 ms is more than enough. It must also be borne in mind that the specification of the monitors is not always real; For example, a Dell U3419W monitor has a GtG response time announced by the manufacturer of 5 ms, but the reality is that if we measure it by hardware this response time goes up to 12 ms.

Do you need such a fast monitor for gaming?

The answer to this question depends on each user and also on the type of game you are playing each time. For example, in a strategy game with isometric view where the camera is static for a long time, you will not notice a much higher response time compared to if you play a shooter or a driving simulator, where the camera is constantly in motion.

What we want to tell you with this is that whether or not you need a 1 ms monitor or similar is a matter of perception. For example, the person signing these lines has a Dell U3415W monitor with 5 ms of advertised response time but 12 ms of actual response time, and at no point have I ever noticed ghosting or other adverse effects due to the response time in no games (and look, I play practically everything). However, other people – especially those used to faster monitors – may notice a big difference.

Technically, it is clear that a 1 ms response time monitor is the best you will be able to have, but it will not necessarily provide you with a better gaming experience than a 5 ms monitor, since this is a matter of perception of each Username. We consider, therefore, that the refresh rate is more important, that it does have a real impact on the eyes, than a better response time. Now, if you can afford both, let no one doubt that it will be the best (in other words, it is clear that the shorter the response time the better, but it is not something that should become required to play).
