Back in November last year, it finally became possible to stream Netflix to your PC in 4K. But in addition to requiring a monitor or TV capable of displaying the resolution, it was revealed that a Kaby Lake processor was a necessity. However, you'll soon no longer need one of Intel’s seventh-generation CPUs to enjoy Netflix content at 3,840 x 2,160 on a PC; a Geforce GTX 10 series graphics card will suffice.
Nvidia is testing a new GPU driver that supports UHD playback on its newest series of GPUs. While the CPU in your PC won't matter, you will need a GeForce GTX 1050 card or better with at least 3GB of RAM to stream Netflix’s 4K videos. As there’s only a 2GB version of the GTX 1050, that means the minimum requirement will be a 1050 Ti (unless another version of the 1050 is on its way).
Additionally, you’ll need a monitor with HDCP 2.2 copy-protection technology, an internet connection of 25 Mbps or faster, and Microsoft’s Edge browser or the Netflix app from the Windows Store. And the feature won’t work on PCs with multiple graphics cards, so if you’ve got an SLI setup, you’ll have to unlink your GPUs if you want 4K Netflix.
“In case of a multi monitor configuration on a single GPU or multiple GPUs where GPUs are not linked together in SLI/LDA mode, 4K UHD streaming will happen only if all the active monitors are HDCP2.2 capable. If any of the active monitors is not HDCP2.2 capable, the quality will be downgraded to FHD,” writes Nvidia.
You’ll still need to use Edge, too, as no other browser natively supports Microsoft’s PlayReady v3.0. GeForce 10 cards also support the copy prevention technology and are able to decode 10-bit HEVC video.
Right now, the “beta” driver is only available for those on the Windows Insider Program. There’s no word on when it will get a public release.
