The Xiaomi Redmi Note 9 Pro may have a DRM Widevine and HD Netflix issue
Xiaomi has had issues with DRM Widevine certification and getting their devices to stream HD content from Amazon Prime Video and Netflix, but we did not think that this would be an issue for the Redmi Note 9 Pro.
The device should be an ideal candidate for content consumption with its large 1080p panel. However, there are conflicting reports about the fate of HD streaming on the device.
On the one hand, @Gadgetsdata claims that the Redmi Note 9 Pro only has L3 Widevine DRM certification. This would extinguish any possibilities of it streaming DRM-protected content in HD. We have been unable to corroborate this though, with Gogi Tech demonstrating that the device is L1 certified. Nonetheless, Time24 reports that the device does not support HD streaming on Netflix.
On the other hand, other outlets claim that the Redmi Note 9 Pro does now support HD streaming on Netflix, but that it did not originally. Specifically, Gizbot states that the device was not whitelisted by Netflix upon release, but it now is.
@Gadgetsdata only tweeted his claim today though, but it could be the case that he has based his findings on outdated or misleading information. Either way, do not take it as a given that the Redmi Note 9 Pro will support HD content from Netflix out of the box. Hopefully, this was an issue at Netflix's end, but that may not necessarily be the case.
