The EasyPen i405X is a graphics tablet (also known as a pen tablet) manufactured by Genius, designed for use in digital drawing, graphic design, and photo editing. It comes with a pen-like stylus that allows users to draw or write directly on the tablet's surface, with pressure sensitivity for fine control.
The EasyPen i405X Windows driver is the software that enables the tablet to communicate with your Windows computer. It translates the input from the pen (such as pressure sensitivity, tilt, and movement) into actions on your screen, allowing you to interact with graphic software like Adobe Photoshop, CorelDRAW, and others.
