Hi everyone,
I’m watching Apple TV through my iCloud+ subscription in Türkiye. The same content looks good on my iPhone and Google TV, but playback quality is very low in both Chrome and Edge on my Windows PC.
Example: Pluribus, Season 1, Episode 8.
What I’ve checked:
- chrome://media-internals confirms an actual video resolution of 862×360.
- The result is identical on my home internet connection and a mobile hotspot.
- Turning graphics acceleration on or off makes no difference.
- Protected content playback and protected content identifiers are allowed.
- NVIDIA Control Panel reports that the system is HDCP capable.
- Disabling Widevine in Edge prevents playback entirely.
- I also cannot access the series in the Windows Apple TV app, which is why I’m using a browser.
The Chrome playback log shows:
key_system: com.widevine.alpha
use_hw_secure_codecs: false
kVideoDecoderName: DecryptingVideoDecoder
In the streaming manifest, SDR variants at 862×360 and below list WIDEVINE_SOFTWARE, while higher-resolution SDR variants require WIDEVINE_HARDWARE. This suggests that the current session’s DRM security level may be limiting the resolution.
My GPU is an RTX 4070. Its driver installation was customized using NVCleanstall; I haven’t confirmed whether that contributes to the issue.
Has anyone managed to get HD Apple TV playback in a Windows browser or resolved this problem? Also, can anyone in Türkiye access the series included with iCloud+ through the Windows Apple TV app?
