Range
The range of the wireless connection provided in the mouse (see "Connection Type").
Almost all modern wireless models work confidently at a distance of at least 2 – 3 metres. So you need to pay attention to this parameter mainly when you plan to use the mouse at a greater distance from the computer — for example, when working with a projector at a presentation. At the same time, when evaluating the range, note that it is indicated for perfect conditions: the absence of interference and obstacles in the signal path, the full charge of the battery in the mouse, etc. In fact, the communication range may be somewhat less, so when choosing, it is worth taking a certain stock. Nevertheless, according to the claimed range, it is quite possible to evaluate the practical capabilities of different models and compare them with each other.
Sensor
The model of the sensor installed in the mouse. This information is indicated mainly for models equipped with high-end sensors, which are significantly superior in their capabilities to simpler solutions. Such characteristics are important primarily for gaming mice, so most of the devices for which the sensor model is specified belong to this category.
Knowing the name, you can find detailed data on the sensor and evaluate its capabilities. Note that one of the most popular brands nowadays, under which advanced sensors are produced, is
PixArt ; on the market are often found, in particular, sensors
PixArt 3212,
PixArt 3325,
PixArt 3327,
PixArt 3335,
PixArt 3360,
PixArt 3389,
PixArt 3395. The second common brand is
Avago (recently owned by the same PixArt); the most popular model of this brand is
Avago 3050, the simplest and most affordable representative of gaming sensors.
Sensor resolution
Resolution of the sensor responsible for tracking mouse movements on the work surface. Specified in DPI — dots per inch.
The physical meaning of DPI as a whole is as follows. The sensor of a modern mouse works on the same principle as the camera matrix, and consists of pixels. And DPI is the number of pixels that fall on 1 inch of the underlying surface (length or width), "visible" by the sensor.
It is believed that more DPI means a more advanced sensor and mouse in general; nowadays, models for
3500 – 5000 DPI,
12000 DPI,
16000 DPI even
more are not uncommon. In a way, it is — high resolution contributes to accuracy. However, the only thing that is directly determined by this indicator is the speed at which the cursor moves across the screen: the higher the resolution of the sensor, the greater the number of pixels that the cursor will move when the mouse itself moves a certain distance. At the same time, it is worth recalling that too high a speed is even more undesirable than too low. So the real need for high DPI (
1000 and above) arises mainly when working on large screens (4K resolution and more); for more modest displays (HD and Full HD), smaller values are often enough.
Max. speed
The ips (inches per second) parameter is the linear speed of mouse movement, expressed in inches per second, at which the manipulator's sensor is able to read the surface. In top models, the maximum mouse movement speed often reaches 400-600 ips, but devices with ips in the region of 200 are more common.
Max. polling rate
The polling rate shows how often the mouse sensor communicates with the computer about cursor movement. The parameter is measured in hertz (Hz), and one second is taken as a unit of time when evaluating it. The smoothness and speed of cursor movement directly depends on the sensor polling frequency. Directly related to this is the mouse response time - this is the time period during which the signal about the movement of the manipulator will reach the display of a change in the cursor position on the screen. Response time is measured in milliseconds (ms). The more hertz the mouse has, the shorter the response time it demonstrates.
DPI level indicator
An indicator showing the current resolution of the mouse sensor.
The DPI value indicator is found only in models that allow you to switch the sensor resolution and are equipped with the appropriate buttons (see above). The indicator allows you to easily monitor the set DPI settings. Note that it does not necessarily show specific numbers — conventions can be used, for example, different backlight colours.
Built-in memory
The presence in the mouse of its own
built-in memory.
The main and, in fact, the only way to use such memory is to store various advanced settings (for example, the functions of programmable keys, or even entire user profiles for various games or other tasks). This feature is relevant mainly for gamers, so almost all models with this feature are gaming.
Lighting
The presence of
illumination in the design of the mouse.
This illumination can be provided by the same LED that illuminates the surface below the sensor, or by separate light sources. It can have a different colour, and the most advanced systems —
RGB backlighting — allow you to adjust the shade to your liking. Anyway, the backlight gives the mouse an unusual and stylish appearance, besides, it can also have special effects (see below). However, this function has not only an aesthetic, but also quite a practical meaning: for example, a colour change can be used as a DPI level indicator (see above) or as a low battery signal. On the other hand, the backlight affects the cost of the device, and the real need for it is not so often — moreover, in many cases (for example, in the office) an extra “illumination” is completely useless. Therefore, most modern mice still do
not have a backlight.
Charging port
— microUSB. One of the miniature versions of the USB connector, still popular in gadgets, despite the emergence of the more advanced USB C. It has relatively modest capabilities (in particular, it is inferior to USB C in terms of the maximum possible charging power), but this point is rarely critical. At the same time, there are a great many cables and chargers for microUSB.
— USB C. The latest (as of the end of 2024) type of USB connector. It is symmetrical, which allows you to insert the cable in any direction, eliminating the possibility of incorrect connection. USB-C is more reliable, has an increased service life and supports higher data transfer and charging speeds. In addition, it is compatible with modern devices and is gradually becoming a universal standard, which makes mice with such a connector more convenient and relevant for users.
