✅ You're Done

You now have a basic understanding of the 2K HDMI Fuser and how the cables are connected.

Initial Setup

  • Disconnect all displays except for the main monitor.
  • Connect the main monitor to the Fuser (not directly to the GPU).
  • Ensure all HDMI cables connected to the Fuser are HDMI 2.0.

Configure Display Settings

On Both PCs:

  • Right-click on an empty area of the desktop.
  • Select Display Settings.
  • Scroll down to the Multiple displays section and select Extend these displays.

On the 2nd PC:

  • Go to Start > Settings > Personalization > Background/Wallpaper.
  • Under Personalize your background, select Solid Color and choose Black.

Reconnect Cables to the Fuser

  • Ensure all three HDMI 2.0 cables are connected to the Fuser.
  • Make sure the monitor is no longer directly connected to the GPU.

Troubleshooting

Desktop Apps Are Merged / Two Search Bars Visible

  • Press K2 (Main Screen Mode) when no overlay is active.

Second Monitor Shows "No Signal"

  • Ensure the 2nd monitor is turned on.
  • The 2nd monitor should be connected to its respective PC, not the Fuser.

Refresh Rate Issues (Limited to 60Hz or 90Hz)

  • This indicates not all HDMI cables are HDMI 2.0.
  • Use three HDMI 2.0 cables for the Fuser setup.
