## Troubleshooting

{% stepper %}
{% step %}

### Desktop Apps Are Merged / Two Search Bars Visible

* Press **K2** (Main Screen Mode) when no overlay is active.
  {% endstep %}

{% step %}

### **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.
  {% endstep %}

{% step %}

### **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.
  {% endstep %}
  {% endstepper %}

{% hint style="danger" %}
The Fuser requires 3x **HDMI 2.0 cables** for full functionality.
