# 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).

{% hint style="info" %}
If you have enabled **DX12 Direct Capture** (an Alpha feature on the Settings page of SimFly Linker) and the image looks wrong, the stream fails to start, or MSFS crashes, first uncheck the option to switch back to the legacy pop-out window capture, then continue troubleshooting. Please also contact us with the aircraft and panel information so we can improve the feature.
{% endhint %}

## 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.

## \[X-Plane / ToLiss] One of multiple popped-out screens shows a black image

When flying a ToLiss aircraft, if you pop out multiple screens at the same time and one of them shows a black image, this is a known issue that may occur on NVIDIA 50-series GPUs — on these GPUs, only the last popped-out window may display an image.

Workaround: enable the **Zink** option in the X-Plane settings.

## “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.
