# Streaming Screen Issues

If the window can already pop out and streaming starts, but the image turns black, becomes unstable, or feels delayed, use this page.

If you cannot pop out the window at all, see [Can’t Pop Up Windows](/v1/troubleshooting/cant-pop-up-windows.md).

## After starting the stream, the image displayed for one second and then went black. (iOS shows “unstable network,” while Android shows “FPS: 0.”) <a href="#after-streaming-the-screen-immediately-displays-unstable-network-ios-or-fps-is-too-low-android" id="after-streaming-the-screen-immediately-displays-unstable-network-ios-or-fps-is-too-low-android"></a>

This issue is still under investigation. So far, it has mainly been observed on a small number of PCs with multiple monitors or specific NVIDIA drivers.

Try the following fixes in order:

1. Change **Pop Out Window Location** in SimFly Linker.
   * **Hidden by default**
   * **Move the popup window to a virtual monitor**
   * **Do not hide**
2. If you use a virtual monitor workflow, confirm the virtual monitor has already been added in SimFly Linker.
3. If you are using a laptop with an external monitor, try pressing ALT+P to exit extended display mode.
4. If you have multiple monitors, try temporarily disabling one monitor in the system display settings.
5. Try a different graphics driver version.

{% hint style="info" %}
If you are using MSFS Pop Out Panel Manager together with SimFly Linker, setting **Pop Out Window Location** to **"Don't Hide"** can help avoid positioning conflicts.
{% endhint %}

If the problem still persists, please contact us and include your graphics card model, driver version, and Windows version.

## “Unstable network” appears after 1-3 minutes of streaming.

{% hint style="warning" %}
This issue is different from the black-screen-at-start problem above. Here, the stream works first and becomes unstable only after 1-3 minutes.
{% endhint %}

We have received feedback from a very small number of users experiencing this issue. Their final solution was to replace the 4 memory sticks they were using (4x16GB) with 2 memory sticks, which resolved the problem.

## Streaming image stuttering or high latency

For iOS and Android versions, the streaming strategy is different.

{% hint style="info" %}
On iOS, streaming does not compress the image, so bandwidth requirements are higher. Streaming a single G1000 screen usually needs around 30\~50Mb bandwidth. We strongly recommend connecting the SimFly Pad device to a 5G Wi-Fi network.
{% endhint %}

{% hint style="info" %}
On Android, the streamed image is compressed, so network requirements are lower. However, compression happens on the PC side and consumes some CPU resources.

If you are using an NVIDIA graphics card, you can change the Viden Encode option to **GPU** in SimFly Linker to reduce CPU usage.
{% endhint %}

Regardless of platform, a 5G Wi-Fi connection is strongly recommended because it usually provides lower latency and a more stable connection than 2.4G Wi-Fi.

## \[iOS] Connection broken after a few minutes

It has been reported that on some iOS devices, AirDrop can monopolize Wi-Fi bandwidth and cause other connections to drop.

You can try:

* Turning off AirDrop and Bluetooth on the iOS device.
* Logging in to your router’s management page and changing the Wi-Fi channel.

## 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://docs.simflypad.com/v1/troubleshooting/streaming-screen-issues.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.
