I understand how disruptive this is, especially when the audio continues normally while the Netflix video remains frozen and eventually becomes completely out of sync.
Since the same behavior occurs in both the Netflix app and different browsers, this may not be limited to a browser cache or extension. It could involve the graphics driver, hardware video decoding, display configuration, or the Windows video playback components.
To help narrow this down, could you please confirm the following?
- What is the make and exact model of your device?
- What Windows 11 version and OS build are you using? You can check this by pressing Windows + R, typing winver, and pressing Enter.
- Does the issue also occur on other streaming services such as YouTube, or when playing a locally saved video?
- Are you using more than one monitor, an HDMI connection, a docking station, or a wireless display?
- Did the problem begin after a Windows update or graphics driver update?
In the meantime, please try these checks:
- Go to Settings > Windows Update, check for updates, and also review Advanced options > Optional updates for any display or graphics driver updates.
- Download and install the latest graphics driver directly from your PC or GPU manufacturer’s support website, then restart the device.
- If multiple monitors are connected, temporarily disconnect the external monitor and test Netflix on the main display. You can also check whether all connected displays are using the same refresh rate under Settings > System > Display > Advanced display.
- In Microsoft Edge, open
edge://settings/system, turn Use graphics acceleration when available off, restart Edge, and test Netflix again. If there is no change, turn it back on and restart Edge once more. - Open the Get Help app, search for Video playback troubleshooter, and follow the diagnostic prompts.
Please let me know the results of these tests. In particular, whether other streaming services or local videos are affected will help determine whether this is specific to Netflix or related to video decoding in Windows.
