| Often friends have encountered a problem, their own mouse access to other people's computer is not fast is slow? After debugging the DPI button on the mouse after the speed of this sense of difference will be reduced.Although the phenomenon caused by the speed of the mouse However, the most important thing is the relationship between screen resolution (PPI) and mouse sensing resolution (DPI).  Today BrotherYi simple to tell you about the mouse DPI and screen speed and intelligence. Pixel world Three Musketeers Red R Green G Blue B. The mouse and the screen one input and one output, the relationship is quite complicated. Their passion collision occurs in the place we do not know, so you need to have a short and correct understanding of it. First simple science now the mainstream of the computer screen - LCD Display of the three principles. First, the principle of the display is the relationship between the graphics card and the display card (GPU) will be complex program information into video signals (HDMI also away from the audio signal), and then the video signal is split into red, green and blue The signal is transmitted to the pixel register corresponding to the screen of the LCD display through a cable.After receiving the signal from each pixel register, the signal is sent to the corresponding pixel according to the red, green and blue liquid crystal cells To match the color, the liquid crystal cell emits light of a specific wavelength and finally mix the correct color.
The second, progressive scan P. As the color conversion signal is continuous, progressive scan is from left to right to wait for a row of color conversion is complete before starting a line conversion relative to the interlace (P) is interlaced (i), the interlacing is to divide the picture into upper and lower parts, first render the cardinal line and the next line pixel in the even line, finally finish the rest of the rendering and recompose the picture (usually no computer monitor is interlaced, PAL system Television generally only interlaced). Our current TVs, monitors are labeled with 1080P, 2K, 4K resolution of these tags to attract consumers to buy. P I have explained, 1080P this data is a complete view of the TV / monitor each ramp 1920 Pixels, 1080 pixels in each column, (LCD pixel spacing is fixed) These pixels follow the progressive scan method to generate the picture. Samsung C27H711QEC E-commerce price Loading... Third, PPI (pixel content per inch.) 1920X1080, 2560X1440, 4096X2160 just tell you the screen resolution unit of size, rather than the final quality. Whether the quality is exquisite or not depends on the PPI index. PPI formula Is: PPI = √ (X ^ 2 + Y ^ 2) / Z (X: the number of pixels in length; Y: the number of pixels in width; Z: the size of the screen.) Now generally not computer monitors generally do not like PPI Marked out, so easy to sell large screen (large particles) high-definition screen, we can use the formula conversion.General 1080P used in 24-inch screen, PPI 91.78 or so feel very comfortable, 32-inch with 1080P resolution, PPI Will plunge to 63.18 grain sense will be quite serious. Mouse facing the track monitor screen Why do so long talk about the monitor resolution, mouse DPI and screen resolution is closely related because the mouse DPI (dot per inch) that the mouse is moving a 1-inch screen will be crossed the number of pixels such as the mouse commonly used 1600DPI that the mouse Each moving a 1 inch across a smooth surface moves the mouse pointer over 1,600 pixels on the screen. For example, the mouse pointer is a sports car Mercedes runs on a track of pixels, and the DPI is a tachometer that reacts to mouse power.
The resolution shows the number of pixels on the screen, and the obvious 4K track of the same spec (same screen and same PPI) has a larger site than 2K, 1080P sites. The mouse DPI is equivalent to horsepower, running at 1080P such as the mountain can not run too high horsepower (high DPI), so that it will not accidentally rushed down the cliff (positioning erratic, making the mouse feel lighter.) In 2K this Of the horsepower, horsepower relative to the 1080P of the Hill certainly larger, so that traffic police will not come over and say you drive too slow in 4K F1 racing circuit, horsepower demand even greater.
Of course, the assumption above is that the PPI on the screen maintains a proper ratio to the screen resolution. The spacing between pixels is a fixed ratio Pixel will be Press this ratio on different screen sizes To put it bluntly, the 1080P track has only so much cement (pixels) to repair the track. No matter how many tracks you need to build (screen size), you have to spread the cement. Every track (size) is suitable The amount of cement (pixels), forced to use 1080P cement to repair the 40-inch 4K track, the cement will be very thin (PPI low-screen particle phenomenon, some manufacturers will use the algorithm to join Interpolation pixels To reduce graininess, but this is also Fake 4K ) With the 4K cement repairing the 1080P track, the cement will be very thick (PPI high screen looks very delicate). The same DPI will have different physical visual effects for different PPI mouse tracking (surely all tracking) The same pixel), this effect is in the human eye is the difference between the speed of the mouse. How to Correct 'Super Run' Mouse If your mouse No DPI adjustment Can not adapt to the complex resolution of the track how to do it? In fact, Microsoft also found that the mouse speed changeable problems, so the windows mouse options Mouse acceleration You can also adjust the speed of the mouse pointer through this option, but Microsoft is through the software program to achieve this function is not to change the physical value of the mouse sensor, so the accuracy of the player in the most demanding will turn off the mouse speed Lest they calculate an error in EDPI (mouse physical DPI multiplied by in-game weight plus) values.
2K, 4K era came, High PPI The screen also more up.To this end, windows and Apple will also remind users of high PPI screen will enlarge the text to a ratio of the PPI close to 90 this ratio is more like the human eye at the same time the mouse DPI do not have to open so high. to sum up: Each screen is a mouse racing circuit, according to different resolution, PPI well adjust your mouse can find the right speed.If you need to use a mouse on several different screen sizes, try the board DPI contains memory records commonly used. Finally BrotherYi have a private goods, if which friends want to share a mouse on multiple devices at the same time, then synergy this software maybe you can try it. |
