Mouse is a very important computer operation peripherals, in the operation of computer control plays a vital role. DPI is one of the most important parameters in determining the performance parameters of the mouse. Often have some netizens asked small edit mouse how to see the dpi, how to see the mouse optical resolution, and so on, the following Triad Small series will be in detail for everyone to share.
How does the mouse look at the DPI
The DPI is the abbreviation for dots per inch, meaning the number of pixels in each inch. Most of the current mouse is a photoelectric mouse, so the DPI is also called optical resolution.
If the mouse dpi is 1000, it means to move the mouse 1 inches, and the mouse pointer on the screen moves 1000 pixels. Therefore, if the computer screen resolution is 1280*800, then the mouse pointer from the leftmost screen to the rightmost need to go through 1280 pixels, so the mouse is actually moving 1280/1000=1.28 inches, 1 inches =2.54cm, 1.28*2.54=3.25cm.
How does the mouse look at the dpi? This mouse optical resolution is not directly in the computer to see, unless the use of some testing software, but at present such software is relatively small, some of the mouse callout dpi value, but the official note sometimes and the actual will also have some errors.
How does the mouse look at the optical resolution?
Measurement of the DPI method of the mouse: measuring the mouse on the monitor through the pixel and the actual move in the example, two data division can get the mouse dpi. Although the principle of testing is simple, it is still difficult to actually calculate it.
If you know the brand model of your mouse, then look at the DPI is more convenient, you can go online to check the brand model mouse parameters, you can find the answer, as shown in the following figure.

As you can see from the image above, the DPI is generally labeled in the mouse parameters, and the dpi of the game mouse is much higher than the dpi of the normal mouse. That is to say, the higher the general DPI, the better, but this is not absolute, some games in the operation, the need for a small dpi, so some professional game mouse can also be very convenient to adjust the DPI.
