🛠 Configure dual 4K displays with HDMI and DisplayPort
Objectives
This tutorial guides users in setting up dual high-resolution displays on the BIOSTAR EdgeComp MS-U320. We will utilize the integrated video ports to extend or duplicate the desktop across two 4K screens, a key feature for graphics-intensive or industrial control applications.
Required Hardware
- 1x BIOSTAR EdgeComp MS-U320 powered on.
- 2x 4K compatible (3840x2160) monitors with HDMI or DisplayPort inputs.
- 1x High-quality HDMI 2.1 cable.
- 1x DisplayPort 1.4 cable (or active adapter if needed).
- USB mouse and keyboard.
Steps
- Port Identification : Locate the two video ports on the rear chassis. One is an HDMI 2.1 port, the other a DisplayPort 1.4. These interfaces support up to two 4K displays simultaneously via the Intel Xe3 graphics.
- Physical Connection : Connect the first monitor to the HDMI port using the HDMI 2.1 cable. Ensure connectors are firmly seated. Connect the second monitor to the DisplayPort with the appropriate cable. Note that the MS-U320 does not have VGA or DVI ports; only these digital standards are available.
- Startup : Turn on the monitors, then boot the mini PC. The OS (Windows 11 or Ubuntu 24.04) should automatically detect both displays.
- Windows Configuration : Right-click the desktop and select « Display settings ». Two numbered rectangles will appear. Drag them to set their relative position (left/right). Choose « Extend these displays » for distinct workspaces, or « Duplicate » for the same image. Set the resolution for each screen to 3840x2160 and refresh rate to 60Hz or higher based on monitor capabilities.
- Linux (Ubuntu) Configuration : Open « Settings » then « Displays ». Both screens will appear. Select « Add Display » if needed, then configure « Extended » mode. Verify the refresh rate is applied to avoid stuttering.
Verification
Ensure the mouse cursor can cross the boundary between screens without issues. Play a 4K video on each screen to check smoothness. If a screen remains black, check the monitor input source or try a different cable.
Further Exploration
Explore local AI features using the integrated NPU (15-16 TOPS) for computer vision tasks displayed on one of the screens. You can also test audio output via HDMI if your monitors have built-in speakers.
