I may be an idiot, but: What does this actually, y'know, achieve? It seems the answer to me is probably nothing? It doesn't work on Firefox. It appears not to work on Chrome. The suggestion is to use Edge, which on Windows already gets 4K support in Netflix anyway.

i don't think it works! there's no mystery here...

I can't vouch for this extension in particular (because I haven't tested it), but I've used and written similar extensions myself and can confirm that the concept is legit.

I never get why those idiots make it harder for paying customers to watch content, than for those just torrenting it. It's the same with Amazon Prime Video which will get me a black screen on Linux or force me to SD Quality, while the torrented Movie runs just fine in 4K

Most users can't tell, and if you deliver the $18/month service while charging $25/month that's $7/month pure profit - money for nothing.

You misread the README. Although it suggests using Edge at the very bottom, the extension doesn't require it and actually spoofs Netflix into thinking it is Edge via changing the user-agent.

For Netflix specifically; it’s because the groups that rip 4K content from Netflix burn a device (i.e. a Widevine L1 key). This is why they typically release 4K Netflix shows in batches.

It's simple: Lawyers creating market for themselves and other lawyers. A head of legal department at Netflix would have a better job and pay if ge has 50x more employees. Hence, the incentive to find ways to get involved in everything, even if it arguably hurts the company's revenue, let alone the rest of the market.

I've spent a long time wondering the same thing. The standard answer is that it's fallout from the anti-anti-piracy cat and mouse game. The more conspiratorial answer is that bandwidth is expensive and streaming sites will take any excuse to serve you a lower resolution than what you actually paid for, while still being able to say that they technically support 4K. There are sensible-ish technical reasons why they ca…

Bandwidth is only expensive if you're getting it from Amazon or Google. Cloudflare gives it away for free.

I believe the benefit for Edge is faking HDCP 2.2.

Then why does the extension try to fake a bunch of other properties, like the user agent and decoding capabilities, which should be redundant?

Is anyone else reading this like WTF I pay for 4K and I dont actually get and I didn’t realize it!?!?!

If you're paying for 4K and you never notice whether what you're watching is actually in 4K, then I have a suggestion for how you can save some $
