3. Setup
3.1. Connecting the Tablet to Your Computer
The Bisofice 12HD-A connects to your computer using a single 2-in-1 USB cable, which handles both power and video signals. No separate power cord is required for the pen display itself.
- Locate the 2-in-1 USB cable. This cable typically has a USB-C connector for the tablet end and multiple connectors (USB-A for data/power, HDMI for video) for the computer end.
- Connect the USB-C end of the cable to the corresponding port on the Bisofice 12HD-A tablet.
- Connect the USB-A and HDMI ends of the cable to the appropriate ports on your computer. Ensure both are securely connected.
- The tablet will draw power directly from your computer via the USB connection.


3.2. Driver Installation
For the tablet to function correctly with pressure sensitivity and custom pen buttons, you must install the appropriate driver.
- Preparation: Before installation, uninstall any other graphic tablet drivers previously installed on your computer. Close all running programs, and temporarily disable any antivirus software or firewalls that might interfere with the installation process.
- Download Driver: Download the latest driver from the official Bisofice website: http://www.bostotablet.com/down.aspx.
- Installation: Run the downloaded installer as an administrator. Follow the on-screen prompts to complete the installation.
- Verification:
- Windows: After successful installation, you should find the "Bisofice Digitizer" icon on your desktop or in the bottom-right corner of your taskbar.
- Mac: The "Bisofice Tablet" icon will appear in your "Launchpad." Click it, and a small icon will show in the top-right navigation bar. Click this icon to open the driver settings panel.
3.3. Screen Calibration
After driver installation, you may need to calibrate the screen for optimal pen accuracy.
- Open the "Bisofice Stylus Configuration Tool" (or similar name) from your desktop or system tray/navigation bar.
- Look for a "Calibration" option within the tool.
- Follow the on-screen instructions to calibrate the pen input to the display. This usually involves tapping specific points on the screen with your stylus.
4. Operating the Tablet
4.1. Basic Usage
The Bisofice 12HD-A functions as a second monitor for your computer, allowing you to draw directly on its screen with the included battery-free stylus. It is compatible with various art software.

4.2. Stylus Configuration
The battery-free stylus offers 8192 levels of pressure sensitivity and features two customizable buttons.
- Open the "Bisofice Stylus Configuration Tool."
- Navigate to the "Drawing Settings" or "Pen Settings" section.
- Pressure Adjustment: Adjust the slider to control the pressure required to draw lines. Moving the slider to the right increases the pressure needed.
- Sensitivity Adjustment: Adjust the slider to modify the variation in line thickness within the same pressure range. Moving the slider to the right increases the variation.
- Custom Buttons: Assign functions to the two buttons on the stylus (e.g., right-click, undo, pan, zoom) according to your workflow. The top button is typically the default right mouse button.

4.3. Tablet Menu Adjustment Keys
The tablet features physical buttons on its side for quick adjustments:
- Menu: Access the on-screen display (OSD) menu.
- Brightness +: Increase screen brightness.
- Brightness -: Decrease screen brightness.
- Return: Exit menu or go back to the previous option.

5. Maintenance
5.1. Cleaning the Tablet
To maintain optimal performance and appearance:
- Use the provided cleaning cloth or a soft, lint-free cloth to gently wipe the screen and body of the tablet.
- Do not use harsh chemicals, abrasive cleaners, or alcohol-based solutions, as these can damage the screen surface.
- Ensure the tablet is disconnected from power before cleaning.
5.2. Replacing Pen Nibs
The pen nibs will wear down with use and should be replaced when they become too short or sharp.
- Use the nib remover tool to gently pull out the old nib from the stylus.
- Insert a new replacement nib firmly into the stylus until it clicks into place.
- Ensure the nib is securely seated before resuming use.
6. Troubleshooting
- Tablet not turning on/displaying: Ensure the 2-in-1 USB cable is securely connected to both the tablet (USB-C) and your computer (USB-A and HDMI). The tablet draws power from the computer. Check your computer's display settings to ensure the tablet is recognized as an extended or duplicated display.
- Pen not working or no pressure sensitivity: Verify that the Bisofice driver is correctly installed. If you have other tablet drivers installed, uninstall them and reinstall the Bisofice driver. Restart your computer after driver installation. Check the pen nib for wear and replace if necessary.
- Lag or delay in drawing: Ensure your computer meets the minimum system requirements. Close unnecessary applications running in the background. Check the driver settings for any performance-related options.
- Inaccurate pen cursor: Perform a screen calibration using the Bisofice Stylus Configuration Tool.
- Screen flickering or display issues: Check the HDMI cable connection. Try a different HDMI port on your computer if available. Ensure your graphics card drivers are up to date.
