Some friends may answer, of course, the higher the better! My answer is that when the budget is insufficient, enough is enough, and when the budget is sufficient, the higher the better. Then I will briefly explain my point of view, hoping to help you.
We increase revenue refresh rate is diminishing marginal, as shown below:
Therefore, according to the picture, as the refresh rate increases, the screen switching time of our monitor is gradually reduced. This also explains that when we upgrade from 60hz to 144hz, we will feel a qualitative leap. But upgrading from 144hz to 240hz, you will feel the reason for the little change.
Economically speaking, as the refresh rate increases, the value of every dollar you spend is gradually decreasing.
