# Troubleshooting & Indicators

### **Indicator Lights (Front Panel)**

* **DC** → Monitor detected
* **RX0** → Host PC detected
* **RX1** → Secondary PC detected
* **RH** → Overlay enabled

{% hint style="info" %}
If a light is **off**, that signal is not detected.
{% endhint %}

***

### **On-Screen Info (Press K1)**

Shows:

* MAIN: Host resolution & Hz
* SECOND: Secondary resolution & Hz
* ALPHA: Overlay strength
* BD: Firmware date
* UID: Device ID
* EDID: Mode A or B
* SEC: Activation status

***

### **EDID Modes (Critical)**

* **Mode A (Default)** – Universal compatibility
* **Mode B** – Native display compatibility

If you get **no image**, switch to **Mode B**\
\&#xNAN;*(Long-press K1 for 5 seconds → auto reboot)*

2. Power off everything → reconnect cables
3. Reset monitor to factory defaults
4. Switch EDID Mode (K1 long press)
