In Pen mode, you use the pen like a regular pen, and you interact with the device as if it is your paper. Each point on the device maps absolutely to a specific point on your monitor, and the cursor jumps to the corresponding point on your monitor when you place your pen on the device.
If you select Pen mode, you can see a representation of how your device maps to your monitors on the Mapping tab. If you want a different mapping than what is shown, you can change it.
In Wacom Tablet Properties, select your pen from the Tool list and then select the Mapping tab.
From Mode, select Pen.
By default, the active area of the device maps to your entire monitor. If you are using more than one monitor, the device maps to all monitors.
CAUTION: If you change the display properties in your computer's display menu, you are also changing the mapping on this tab.
From Screen Area, select which part of your monitor that you want the device to map to:
Select Full if you want to map to the entire area of the monitors connected to your computer.
Select Portion if you want to define a section of your monitor to map to. Select the section in any of the following ways:
Under Drag Handles, drag the corners of the red border to define the screen area that you want to map to.
Select Click to Define and use your cursor to select the screen area that you want to map to.
Enter Coordinates in pixels.
Select a Monitor if you want to map to the entire area of a single monitor.
From Tablet Area, select which part of your device that you want mapped to the Screen Area you selected.
The options are similar to the Screen Area options.
Select Force Proportions if you want the vertical and horizontal proportions to be the same on your device as on your monitors.
If you select Force Proportions and draw a circle on the device, it displays as a circle on the screen, but a portion of the device active area may no longer be usable.
If you do not select Force Proportions and draw a circle on the device, it might display as an ellipse on the screen.
Tip: To help you decide which setting to select, watch the red borders of the image on this tab while selecting and unselecting Force Proportions to see how it affects mapping.
