• Mirrored Mode (SST): All displays (laptop and external monitors) show the same content.
• Note for Mac M1/M2/M3 Chips: If connecting to a Mac with M1, M2, or M3 chips, it only supports a single HDMI output and cannot support output to 2 HDMI monitors simultaneously.

5. Resolution Support

• Single HDMI Output: Maximum resolution up to 4K@60Hz.

Figure 7: When two HDMI outputs are connected simultaneously, the maximum resolution for both monitors is 4K@30Hz.

6. Troubleshooting

• Only 1 monitor display, second monitor blurry:
  Firstly, ensure you are using an HDMI 2.0 cable, and its length does not exceed 3m. Then, set the input source resolution to 1080P@60Hz to check if it displays correctly.
• Product not working on laptop USB-C port:
  Please make sure that your USB-C port supports DP ALT mode or video output. If not, this product will not work on that device.
• How to set extended mode on Windows system:
  Select 'Settings' on laptop -> 'System' (Display, Sound, Notifications, Power) -> 'Display' -> 'Multiple displays' -> 'Extend these displays'. If the display is not detected, manually select 'Detect' and then 'Apply'.
• How to switch from 'mirror display' to 'extended ABB mode' on Mac OS system:
  Select 'Settings' -> 'Display' -> Click the 'Mirror display' box to switch to extended mode. Drag the window of document/video/website to the rightmost side of the desktop screen until it disappears on the external monitor screen.
