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.
Contrast
The contrast of the screen set in the graphic display (see "Type").
This setting describes the brightness ratio between the brightest white and darkest black that the screen is capable of reproducing. The larger the first number, the higher the contrast and the better the image as a whole. However note that the contrast ratio of modern graphic displays usually ranges from 400:1 to 3000:1 — this is generally noticeably lower than that of computer monitors, especially professional ones. So the final control of the result is still best done on the monitor. On the other hand, if you are going to work professionally with graphics on a tablet display, it makes sense to look for a model with high contrast.
