Keep in mind, some fixes depend on your hardware and software setup, so make sure to read carefully.

Quick Note: Prerequisites and Initial Checks

  • Netflix Plan: Ensure your Netflix subscription supports 4K streaming. Only the Premium plan offers 4K content.
  • Supported Browser: Use Microsoft Edge or the Netflix app from the Microsoft Store. Other browsers like Chrome or Firefox don’t support Netflix 4K playback on Windows.
  • Compatible Hardware: Your PC needs a 4K display and a CPU/GPU that supports HDCP 2.2 and PlayReady 3.0 DRM.
  • Internet Speed: Netflix recommends at least 25 Mbps for smooth 4K streaming.

Checking these basics before troubleshooting saves time and avoids unnecessary steps.

Step 1: Verify Your Netflix Plan and Browser

First, confirm that your Netflix plan supports 4K playback. You can check your plan by logging into your Netflix account and reviewing the subscription details.

Next, use Microsoft Edge or the official Netflix app from the Microsoft Store to watch 4K content. Other browsers do not support Netflix 4K streaming due to DRM limitations.

Step 2: Update Windows 11 and Microsoft Edge

Keeping your operating system and browser up to date ensures compatibility and access to the latest features.

  • To update Windows 11:
    1. Click the Start menu and select Settings.
    2. Go to Windows Update on the left sidebar.
    3. Click Check for updates and install any available updates.
  • To update Microsoft Edge:
    1. Open Edge and click the three dots (…) in the top-right corner.
    2. Select Settings > About Microsoft Edge.
    3. Edge will automatically check for updates and install them.

Updates often fix bugs and improve DRM support, which is crucial for Netflix 4K.

Step 3: Enable Hardware-Accelerated Streaming

Hardware acceleration allows your PC to use GPU resources for smooth video playback, important for 4K streams.

To enable hardware acceleration in Edge:

  1. Open Microsoft Edge and go to Settings.
  2. Navigate to System and performance.
  3. Toggle on Use hardware acceleration when available.
  4. Restart Edge to apply changes.

If hardware acceleration is off, videos may stutter or Netflix 4K might not work properly.

Step 4: Check Display Settings for 4K Resolution

Your monitor needs to be set to 4K resolution to enjoy Netflix in 4K.

  • Right-click on the desktop and select Display settings.
  • Under Display resolution, choose the recommended 3840 x 2160 (4K) option.
  • Click Apply and confirm the change.

If your display isn’t set to 4K, Netflix will automatically stream lower resolutions.

Step 5: Confirm HDCP 2.2 Compatibility

HDCP 2.2 is a security protocol required for 4K playback. Both your display and graphics card must support it.

To check this:

  • Consult your monitor’s specifications or manual to confirm HDCP 2.2 support.
  • Check your graphics card details on the manufacturer’s website.

If your hardware lacks HDCP 2.2, 4K streaming won’t be possible on Netflix.

Step 6: Use the Netflix App for Windows 11

Using the Netflix app from the Microsoft Store is often easier and more reliable for 4K playback compared to browsers.

  • Open the Microsoft Store app on your PC.
  • Search for Netflix and install the official app.
  • Log in and try playing 4K content.

The app supports DRM and hardware requirements needed for 4K better than many browsers.

Step 7: Update Graphics Drivers

Outdated or corrupt graphics drivers can cause playback issues.

To update your graphics driver:

  1. Press Win + X and select Device Manager.
  2. Expand Display adapters.
  3. Right-click your graphics card and choose Update driver.
  4. Select Search automatically for updated driver software.
  5. Follow prompts if updates are available.

Alternatively, visit your GPU manufacturer’s website (NVIDIA, AMD, Intel) for the latest drivers.

Step 8: Disable VPN or Proxy Services

VPNs or proxies can interfere with Netflix’s content restrictions and streaming quality.

If you use a VPN or proxy, try disabling it and then check if 4K playback works.

Step 9: Clear Netflix App or Browser Cache

Corrupted cache files might prevent smooth streaming.

For Microsoft Edge:

  1. Open Edge and press Ctrl + Shift + Delete.
  2. Select Cached images and files and Cookies and other site data.
  3. Click Clear now.

For Netflix app:

  • Go to Settings > Apps & features in Windows.
  • Find Netflix, click it, then select Advanced options.
  • Click Reset to clear app data.

Step 10: Use Windows 11’s Troubleshooter for Video Playback

Windows has built-in tools to diagnose and fix video playback issues.

  1. Open Settings and go to System > Troubleshoot > Other troubleshooters.
  2. Find Video Playback and click Run.
  3. Follow the on-screen instructions to detect and fix problems.
