Chalk this one up as mildly infuriating. In the past, we've covered Netflix's 4K streaming limitations and how the platform was limited to handful of televisions, even though PCs are easily capable of handling 4K. Now we know that 4K content is officially coming to the PC with the release of some Gilmore Girls episodes in partnership with Microsoft, but chances are you can't watch it in that mode. To view 4K Netflix, you'll need a Windows 10 PC, Microsoft Edge, and a seventh-generation processor from Intel.
Given that Kaby Lake is so new that neither Microsoft nor Apple could be arsed to include it in their own recent hardware refreshes, making 4K Netflix content depend on it is icing on the cake -- particularly given that there's going to be essentially zero benefit from stepping up to 4K as opposed to 1080p on an 11-15-inch laptop display. (As always, the benefits of higher resolution content depend on how close you sit to the display, but relatively small laptop and tablet screens won't see dramatic gains). It'd be interesting to see how Netflix's 4K compares with 1080p from Blu-ray, both native and upscaled to 4K, though that's a question for another day.
Microsoft's blog post(Opens in a new window) on the topic directs readers to check the Microsoft Store for more information on which systems qualify as 4K capable. The link redirects to one system -- the Lenovo Yoga 910. After Lenovo's disastrous security issues, I no longer recommend Lenovo hardware for any reason. It scarcely matters. This is one capability that may technically exist today, but it'll be months before hardware is widely available to take advantage of it -- and it'll never come to previous generation hardware at all.
