In a world where multitasking has become the norm rather than the exception, a single laptop screen often feels like a limitation. Whether you're juggling spreadsheets, attending virtual meetings, coding, or managing creative projects, constantly switching between tabs and windows can slow you down and drain your focus. The modern workflow demands more visual space, more flexibility, and more efficiency—without necessarily investing in bulky desktop setups.

For digital professionals, students, and remote workers alike, the idea of expanding a laptop into a multi-screen workstation is no longer a luxury—it’s a practical upgrade. Traditionally, achieving this meant connecting to external monitors, dealing with cables, and sacrificing portability. But what if you could carry your entire multi-screen setup with you, and transform your laptop into a triple-screen productivity hub anytime, anywhere?
This guide explores exactly how to make your laptop function like three laptops simultaneously. Beyond just step-by-step instructions, it introduces a powerful and portable solution: the Blackview DCM8 laptop screen extender. With its dual-screen design and thoughtful features, it redefines what mobile productivity can look like.
Why Turn One Laptop into Three?
Before diving into the “how,” it’s important to understand the “why.” A triple-screen setup significantly enhances productivity by allowing you to:
- View multiple applications simultaneously without toggling
- Separate workflows (e.g., communication, research, execution)
- Improve focus and reduce cognitive overload
- Enhance multitasking efficiency for creative and technical tasks
For example, imagine writing a report on your main screen, referencing materials on one side, and keeping communication tools open on the other. This setup mimics having three separate devices—but without the clutter.
Step-by-Step: Transforming Your Laptop into a Triple-Screen Workstation
Step 1: Choose the Right Screen Extender
The foundation of this setup is a reliable screen extender. The Blackview DCM8 stands out because it offers two additional displays that attach directly to your laptop. Unlike traditional monitors, it’s designed specifically for portability and ease of use.
Key highlights include:
- Dual 15.3-inch IPS FHD screens
- 16:10 aspect ratio for more vertical workspace
- Built-in speakers on both screens
- TÜV SÜD Low Blue Light Certification for eye comfort
These features ensure that you're not just adding screens, but upgrading your overall viewing experience.
Step 2: Physically Attach the Screens
The Blackview DCM8 is designed to fit laptops ranging from 14” to 17.3”. Installation is straightforward:
- Extend the mounting frame and attach it to the back of your laptop screen
- Pull out the two side screens—one to the left, one to the right
- Use the built-in support stand at the back for added stability
The entire setup takes just a few minutes and requires no technical expertise.
Step 3: Connect via USB-C
The device uses universal USB-C ports, making it compatible with most modern laptops. Simply:
- Plug the USB-C cables into your laptop
- Ensure your laptop supports display output via USB-C (most do)
One standout feature is its support for 100W reverse charging, meaning your laptop can stay powered while running the extended screens—reducing the need for extra chargers.
Step 4: Configure Your Display Settings
Once connected, your operating system will detect the additional screens. You can then configure them:
On Windows:
- Go to Display Settings
- Select “Extend these displays”
- Arrange the screens according to your physical setup
On macOS:
- Open System Settings → Displays
- Drag to arrange screens
- Enable extended desktop mode
The Blackview DCM8 supports multiple systems, including Windows, macOS, Android, Linux, and Chrome OS, making it highly versatile.
Step 5: Adjust Viewing Angles
Comfort is crucial for long working sessions. Each screen on the Blackview DCM8 supports 180-degree rotation, allowing you to:
- Tilt screens for optimal viewing angles
- Rotate for presentations or collaboration
- Customize your setup based on your posture or environment
This flexibility ensures that your triple-screen setup adapts to you—not the other way around.
Practical Use Cases
1. Remote Work Efficiency
Keep video calls on one screen, documents on another, and emails or chat tools on the third.
2. Content Creation
Edit videos or images on your main screen, preview outputs on one side, and manage assets on the other.
3. Programming & Development
Write code on one screen, run output or debugging tools on another, and keep documentation open on the third.
4. Trading & Data Analysis
Monitor charts, execute trades, and track news feeds simultaneously without overlap.

- Adjust brightness and color settings to match across screens
- Take advantage of keyboard shortcuts for faster navigation
