What it is: The sensor is one of the components that translate the mouse movement into a cursor movement.
When It Matters Having a well-chosen sensor can make a big difference for gamers, and even influence the outcome of a game. What it is: The combination of light and sensors used to process and detect movement on a surface. Laser mice have the ability to work better on glossy surfaces or glass because of their ability to look deeper into the surface. As a trade-off, the sensor can take too much information off the surface, causing inconsistencies in the movement of the cursor, especially at high speed.
Optical LED mice generally offer a more consistent cursor movement, but can be hard to use on glass or a glossy surface. When it matters: When gaming, an Optical LED sensor usually offers more consistency in the mouse movement.
On the other hand, if you're looking for a mouse that works across a wide range of surfaces, laser is usually a better choice. What it is: The model number or name of the sensor in the mouse. When it matters: For most advanced users and gamers it can be important to choose a sensor they know fits their performance needs. CPI counts per inch or DPI dots per inch represent the number of steps the mouse sensor reports when moving one inch.
A lower CPI DPI has the effect of reducing the distance the cursor moves onscreen when moving the mouse a fixed distance. We display the manufacturer's value. When it matters: When your comfortable CPI is low and you want to know if the mouse can achieve it. Score distribution. CPI counts per inch or DPI dots per inch represents the number of steps the mouse sensor reports when moving one inch.
A higher CPI DPI has the effect of augmenting the distance the cursor moves onscreen when moving the mouse a fixed distance. When it matters: When your comfortable CPI is high and you want to know if the mouse can achieve it. When it matters: When you're looking for a mouse with consistent cursor movement. We set the CPI to , or as close as possible, and ensure the mouse's acceleration and multiplier are turned off in Windows. We then position the mouse on the modified mouse pad, on the top left hole see picture.
We click and drag the mouse following a predetermined pattern at low speed. We write down the error percentage given in the Deviation section of the website and do this nine more times to validate the result and calculate an average. After that, we click and drag the mouse again, but at high speed.
What it is: The distance between the mouse and the surface where the sensor can't detect movement anymore. Values are in increments of 1. When it matters: When you're used to a low lift-off distance, switching to a high lift-off distance could be bothersome when you're trying to lift the mouse to re-position it without any unwanted cursor movement.
When gaming, a low lift-off distance is usually better so you don't have to lift your mouse high to re-position it without any cursor movement. Good value: 2. What it is: Polling rate represents the amount of time per second the mouse reports its position to the computer. When it matters: When playing a fast-paced game, a higher polling rate offers a smoother cursor movement.
Good value: Hz or higher. So with all this in mind, what is the CPI button on a mouse used for? Most of the standard mouse models available today have a fixed sensitivity. You cannot change the CPI parameter of these regular mice other than through the control panel. The difference between a gaming mouse and a regular one is the presence of a special button the CPI button that is used to change the resolution. Using the CPI button, a gamer can change the sensitivity. For example, changing the sensitivity can help gamers who play shooting games for much more accurate aiming.
The higher the CPI, the faster the cursor will move on the screen. Judging a mouse solely based on its CPI can be quite misleading. Unfortunately, mouse manufacturers will sometimes inflate the true CPI capabilities of their products by using firmware to cover up lesser sensors.
The last thing you would want is to buy a mouse with glowing reviews thinking you are getting a high-performance sensor only for your gaming experience to be bogged down by firmware processing instead of real 1 to 1 tracks. In this article, we are going to discuss all that relates to the CPI button on your mouse, including what it is used for, how to use it, and how to test it. Therefore, if you are an avid gamer, and looking to get informed about this, read on to find out more. For the most part, these two are different from each other.
In this article, we are more interested in CPI. This generally refers to the sensitivity of the mouse. The higher the CPI level of a mouse, the more sensitive the mouse will be to your movements. The number means how many pixels can fit one inch on the surface of the mouse sensor. The most standard and regular mice available today have a fixed sensitivity, and you cannot change the parameter of these mice other than through the control panel.
Therefore, these mice will most of the time not have a CPI button. However, the case is quite different for gaming mice. Gaming mice will usually come with a CPI button. But what most gamers who are new to this phenomenon wonder is what this button is used for. If you are one such person, then I have just the answer for you. Depending on the amount of CPI options on your mouse, each time you click the button, your mouse will get considerably faster until you reach the limit, after which it will go back to the slowest limit.
Begin typing your search term above and press enter to search. Press ESC to cancel. Ben Davis April 20, What is CPI switch button? What does CPI stand for on my mouse? What CPI should I use for mouse? How do I find my CPI mouse? Where is the CPI button on my mouse?
With me so far? So, if that wasn't confusing enough, CPI stands for counts per inch, which generally refers to the sensitivity of a mouse. The higher the CPI, the more sensitive it is to your movements. You can look at it as the number of 'steps' the mouse's sensor reports to your computer when it movies one inch, but what the number really is referencing is how many pixels fit into one inch on the surface of the mouse sensor, which is a bit like the CMOS sensor of a digital camera.
So, when you look at a mouse's sensitivity range, let's say ,, that means it can make anywhere between to 12, steps per inch. A lower number will make the mouse cursor appear to move more slowly, and you'll have to move your mouse further across your desk to get the cursor to move to the other side of the screen.
A higher number will require less movement on your part. If your mouse has a little button beneath the scroll wheel, some manufactures might call it a DPI switch, but it's really a CPI switch. It also doesn't help clarify things when some manufactures like Logitech not only refer to its CPI settings as DPI, but refer to it as the 'resolution' range as well.
CPI gets even more complicated when you factor in a few more things.
