# 1K Fuser Setup

***

{% stepper %}
{% step %}

### 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**.
  {% endstep %}

{% step %}

### 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**.
  {% endstep %}

{% step %}

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

***

## 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.
{% endhint %}

### ✅ You're Done

{% hint style="success" %}
Your 1K HDMI Fuser is now setup and ready to use!

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://cookiebunker.gitbook.io/cookiebunker/dma/1k-hdmi-fuser/1k-fuser-setup.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
