2️⃣ Input 1 → Main PC • Connect HDMI (2.1) or DP (1.4) from your Main PC’s GPU to Input 1 on the Fuser.

Important Notes

  • The main PC’s GPU must not be connected directly to any monitor during setup. If a direct DisplayPort or HDMI cable is plugged into the monitor, unplug it before setup.

  • Once all connections are made, you may power on the Fuser, then both of your PCs.

  • Using mismatched or lower-grade cables (HDMI 2.0 / DP 1.2) can result in no signal or screen flickering.
