The word "ppp" means "dots per inch»Or a word that sounds like you, a DPI which means« dots per inch & # 39 ;. This parameter is directly related to motion readings made by the sensor, that is, for example, a mouse with 2000 DPI means that for every inch (2,54 cm) moving a mouse, it will be able to send 2000 readings or motion signals to the PC.
This is also known for how many "pictures" the mouse can take each second, so to speak to more dpi, more photos
For this reason, in fact, it is more accurate to call this CPI CPI (inch count) than DPI or dpi because this is related to the pixels on the screen. For example, a mouse with 2000 CPI will move 2000 pixels to the screen for every inch that moves the mouse.
What is ppp influencing mouse performance
Prior to the previous description you will have already noticed that it is not as good as ppp or DPI as CPI (and, in fact, manufacturers call it incorrect), and they actually do not provide traditional sensor sensitivity data since in fact, at very high sensitivity values what the sensor does. divide pixels into subpixels
For this reason, if you have an example to monitor 4K but go into the game and the screen is set to full HD resolution, you will notice that the mouse suddenly moves faster on the screen than it did on the desktop. This is because the fact is that sensors measure their sensitivity to CPI with this it has a direct relationship to the screen resolution, so mouse performance will change dramatically in this case.
This is why it is important to look at these parameters before choosing a mouse, especially if it is a play mouse. If a mouse claims to have 1 dpi (or SteelSeries calls it, TrueMove) it means that the movement you make mat or more with the mouse will be displayed 1 to 1 on the screen, bringing a more accurate performance but, above all, more accurate.
To summarize: if you are playing on a laptop with a resolution of 1366 x 768 or full HD (1920 x 1080), it will be worth a mouse with a low dpi signal so that your movement is more compatible with the solution, while using it on an UltraWide or 4K screen , then a higher dpi value is appropriate for this reason.
