Workspace
The exact size of the active area of a tablet (or screen in a graphic display) in width and height. In general, it is more of a reference than a practically significant parameter: when choosing a traditional graphics tablet, there is often enough information about the format (see above), and for displays, primarily the diagonal (see above) and aspect ratio (see below) are of practical importance . However, the exact dimensions can also be useful in fact: for example, you can determine the aspect ratio from them (for classic tablets, this parameter is often not indicated).
Size
Diagonal of the working area — the screen itself — in a graphic display (see "Type").
In general, the larger the diagonal, the more convenient the device is to use: a large working area covers a large area for drawing and at the same time allows you to work effectively with small details. On the other hand, this parameter directly affects the price, and the dimensions cannot be discounted: in some cases, there may simply be no room for a large device.
By the standards of graphic displays,
13.3" or less is considered small,
15.6" is considered medium, and many models have
larger screens. And it is customary to evaluate the size of traditional tablets by the format, and not by the diagonal.
Scroll wheel
A wheel for scrolling content on the screen, similar to that used in modern computer mice. A similar wheel is placed on the side or top of the graphics tablet case. It is used for quick navigation through graphical applications, documents or web pages. At the same time, the scroll wheel has expanded functionality - by pressing it you can perform certain commands or gestures such as zooming an image, scrolling horizontally, etc.
Video transmission
-
HDMI. A digital video interface found in graphic displays and computers (see Type). Models with an HDMI port are capable of receiving and transmitting video signals to devices connected via an appropriate cable. Moreover, HDMI supports the transmission of digital signals without loss of quality, providing a high-quality picture (and, if necessary, sound). To connect via HDMI, various options can be used, including the use of adapters for USB type C or miniHDMI connectors.
-
DisplayPort. A digital interface similar in connection capabilities to HDMI (see above). It supports high-definition video (1080p and above) along with multi-channel audio. Such interfaces are rare in graphics tablets - they remain the prerogative of a small number of advanced professional-class models.
-
DVI. Digital input for connecting a video signal from a computer. Found exclusively in graphic displays (see "Type"). Note that DVI outputs are often provided in desktop PCs, but are practically not found in laptops; on the other hand, a tablet with such an input can be connected to a laptop HDMI video output using a simple adapter.
-
VGA. Aka 15-pin D-Sub. Another video interface found in graphic displays. It uses an analog signal format and is poorly compatible with resolutions higher than 1280x1024, which is why it is c
...onsidered obsolete and is usually provided in modern graphic displays as a “backup” option, in addition to the digital DVI described above.Brightness
The maximum brightness in cd/m² that the device screen produces.
High brightness displays remain highly readable under intense ambient light, such as when the workplace is exposed to sunlight. A dull image on a graphics tablet screen can be “blown out” by such lighting. Note that a large margin for this parameter affects the cost and power consumption of the display.
Colour depth
The number of shades that the device screen can display. The parameter is indicated in bits, not for the entire display, but for each individual base color. Let us remind you that the image in modern screens is based on three basic colors according to the RGB scheme - red, green and blue. 6-bit depth means that the display is capable of producing 2^6 shades of each base color, i.e. a total of 64 shades of red, green and blue. The total number of shades is 64*64*64 = 262,144 (262 thousand). In screens with
8-bit depth, there are already 256 shades for each basic color - in total, they are capable of displaying over 16.7 million colors. And the most advanced displays support
10-bit color depth, allowing you to work with more than a billion shades.
High color depth is important for professional graphics and related tasks that require high color accuracy.
