* Ensure your WLED device is configured for this total number of LEDs and that the segments are correctly defined to match your physical setup.
* Enable "UDP Realtime" in WLED settings and ensure it's listening on port 4048 (or the port you specify with `-p`).

Our `Hyperion_Grabber_X11_QT` project aims to replicate this Ambilight functionality by:
* **Screen Capture:** The `WaylandGrabber` (or X11 grabber) captures the screen content.
* **Screen Capture:** The `WaylandGrabber` (or X11 grabber) continuously captures frames from your screen.
* **Image Processing (`HyperionGrabber`):** The captured `QVideoFrame` is converted to a `QImage` and then scaled down (`scaledImage`). This `scaledImage` represents a lower-resolution version of the entire screen.
* **Color Extraction/Mapping (Implicit in `WledClient`):** This is where the crucial step of mapping the `scaledImage` to the individual LEDs happens. The `WledClient` iterates through the pixels of the `scaledImage` and sends them as RGB data to the WLED device.
