You cannot drive two independent external monitors from a single USB3.2 Gen1 Type-C port on the ASUS Vivobook X415EA using a standard passive hub like the Baseus Portal Joy. This limitation exists because the laptop’s video output relies on DisplayPort Alternate Mode, which typically supports only one display stream per physical port unless specific Multi-Stream Transport (MST) conditions are met, which this hardware combination does not satisfy.
The Hardware Limitation Explained
The core issue lies in how the ASUS Vivobook X415EA handles video signals through its USB-C port. Unlike dedicated docking stations that contain their own graphics processing units or support DisplayLink technology, the Baseus Portal Joy is a passive hub. It simply passes the signal from the laptop to connected peripherals. When you connect a single monitor via HDMI or DisplayPort to the hub, the laptop sends a video signal through the USB-C connector using DisplayPort Alternate Mode. However, most consumer laptops, including the Vivobook series with integrated Intel UHD or Iris Xe graphics, do not support splitting a single DP Alt Mode signal into two distinct desktops via a passive hub. The operating system sees the hub as a single display endpoint, not a multi-display array. Attempting to force this setup often results in one of two outcomes:- Duplicate Display: Both monitors show the exact same image. This is useful for presentations but useless for productivity.
- No Signal: The second monitor remains black because the GPU does not allocate resources for a second independent stream over that single connection path.
Viable Workarounds for Dual Monitor Setup
To achieve a true extended desktop experience with two external monitors on your Vivobook X415EA, you must utilize separate video output paths. The laptop typically offers two main avenues for video: the built-in HDMI port and the USB-C port. Method 1: Use HDMI and USB-C Simultaneously This is the most reliable solution for your specific hardware. You should connect one monitor directly to the HDMI port on the laptop and the second monitor to the Baseus Hub, which is plugged into the USB-C port.- Connect Monitor 1: Plug an HDMI cable from your first monitor directly into the HDMI port on the side of the ASUS Vivobook.
- Connect Monitor 2: Plug your second monitor into the HDMI or DisplayPort slot on the Baseus Portal Joy hub.
- Plug in the Hub: Connect the Baseus Hub to the USB3.2 Gen1 Type-C port on the laptop.
- Configure Displays: Right-click the Windows desktop and select Display settings. Under "Multiple displays," choose Extend these displays.
- Purchase a USB-to-HDMI adapter that explicitly states it supports DisplayLink technology.
- Install the latest DisplayLink driver software from the manufacturer’s website.
- Connect the adapter to any available USB-A or USB-C port on the laptop.
- Connect your second monitor to this adapter.
Why MST Doesn’t Work Here
Some users might suggest using Multi-Stream Transport (MST) to daisy-chain monitors or use a hub that splits the signal. While MST is a real technology, it requires three things to work:- A GPU that supports MST.
- A monitor or hub that supports MST input.
- Cables that carry the full DisplayPort signal.
Performance Considerations
When using the HDMI + USB-C method, ensure your BIOS is up to date. ASUS occasionally releases updates that improve peripheral compatibility. Additionally, verify that your graphics drivers are current. Outdated Intel HD/UHD drivers can sometimes prevent the system from recognizing multiple displays correctly. You may also notice that the USB-C port shares bandwidth with other devices. If you plug in high-speed storage drives along with the monitor hub, you might experience minor stuttering. In such cases, prioritize the monitor connection on the USB-C port and use USB-A ports for data storage.Frequently Asked Questions
Can I use two USB-C hubs to get four monitors?
No, not with standard passive hubs. Each USB-C port on your laptop generally provides only one independent video stream. To get more than two external displays, you would need at least one DisplayLink adapter or a Thunderbolt dock with dedicated graphics processing capabilities.
Will updating my BIOS fix the dual monitor issue with the Baseus hub?
Unlikely. The limitation is architectural, stemming from how the Intel integrated graphics handles DisplayPort Alternate Mode over USB-C. While BIOS updates can fix bugs, they rarely change fundamental hardware constraints regarding video signal splitting on non-Thunderbolt ports.
Is there any software setting to enable dual monitors on one USB-C port?
No software setting can overcome this hardware limitation. The operating system receives a single display identifier from the hub. Without additional hardware like a DisplayLink chip to process multiple streams, no driver or Windows setting can create a second independent desktop from that single source.
Does the Baseus Portal Joy support DisplayLink technology?
No, the Baseus Portal Joy is a passive hub. It does not contain a DisplayLink controller or any internal graphics processing unit. It merely extends the USB and video connections from the laptop. You must look for products specifically labeled as "DisplayLink Dock" or "Active Adapter."
Can I use a USB-C to DisplayPort cable instead of the hub?
This will still only give you one additional monitor. A direct USB-C to DisplayPort cable connects one display to the laptop’s video output. It does not provide a mechanism to split the signal for a second monitor. You would still need to use the HDMI port for the second screen.
