Enabling HDR slows down the Internet in Windows 10

I recently enabled HDR on my Windows 11 computer, but noticed that it caused my Internet connection to slow down noticeably. After some research, it appears that this issue is related to how the system handles bandwidth when displaying HDR content.
 
I therefore seek your advice and suggestions to resolve this problem. If anyone has encountered this problem before and found a solution or trick to mitigate this effect on internet connection speed, I would be grateful to share it.

    Enabling HDR on Windows 11 can sometimes lead to unexpected issues, including network performance drops. While HDR itself primarily affects display output, certain system configurations or driver issues can cause interference with network performance.

    HDR (High Dynamic Range) on Windows 11 enhances display quality but can sometimes impact system performance, including network speed, especially if your system reallocates resources or if certain background processes are affected.

    Experiencing a slowdown in your internet connection after enabling HDR on Windows 11 is unusual, but it can happen due to how Windows manages display settings and network priorities.

    Some graphics driver settings or bugs may cause system resources to be misallocated, affecting network performance.
