It's not as hard as it once was to procure content that takes full advantage of our beefy 4K televisions (and monitors), but to some, 4K is just half of the equation. The other half, of course, is HDR (high-dynamic range). With HDR, colors will look far more varied (hence, "range"), and accurate. In effect, colors will pop, and to borrow a tired phrase, make images "look more lifelike than ever".
Netflix hasn't just begun supporting HDR, but has just begun supporting it on the PC. If you've been on the hunt for 4K Netflix in the past on your PC, the solution is probably not going to come as a surprise: Microsoft Edge. Alternatively, you can also use the Netflix app available from the Windows Store, for an arguably more streamlined experience.
"But wait, that's not all!" If only the support requirement stopped at the software. As with Ultra HD content, HDR will require a 7th-gen Intel processor, or better, or, a current-gen NVIDIA GeForce GPU, GTX 1050 or better. In both cases, the latest version of Windows 10, Fall Creators Update (1703), is also required.
Unfortunately, Netflix HDR support on AMD platforms is non-existent, which is going to be quite a bummer for those running pure AMD rigs. If you do happen to run Ryzen, and manage to stream HDR content no problem, please let us know in the comments!
Up and running and want to find some HDR content? Since Netflix doesn't seem to have a dedicated section, simply searching "HDR" will bring up relevant content. You probably shouldn't be surprised to see that almost all of it is Netflix's own content. Sometimes, you just gotta get the job done yourself.
