I just purchased a Dell OLED monitor AW3423DW, and I was thinking finally I can enjoy Netflix 4K on my computer not.  But, things are not easy, Netflix can only play content content in HD (1080p). And I did some research and finally got Netflix working with 4K HDR.

Here are the steps you need to do:

1. Check your Graphics cards to make sure it supports HDCP 2.2, which means the video card need to have HDMI 2.0 or DisplayPort 1.4 or higher. I’m using old Nvidia GTX980, so I can only play Netflix with 1080p…. So Upgraded it to Nvidia RTX3070.

2. Enable HDR and Enable “Play streaming HDR video” in Windows Display settings.

3. Purchase and install HEVC Video Extensions from Microsoft Store.

4. Enable “Hardware Acceleration” in Edge via Settings – System and Performance – Use Hardware Acceleration. Only Edge or Chrome can play Netflix in 4K, Firefox or Netflix App can only stream 1080p content on windows.

5. Enter edge://flags in the URL bar and open,  Find PlayReady DRM for Windows 10/11 and select Enable. Then restart Edge.

For now you should be able to watch Youtube HDR content. But to watch Netflix in 4K, there is one more step…

6. If you have multiple monitors, you need to turn off any monitor not support HDCP 2.2. For example, my old Dell UP2716d monitor only has Display port 1.2 and HDMI 1.4 which both are not support HDCP 2.2. I need to turn the off before I start Edge, otherwise Netflix will only stream in 1080p.

After complete above steps, in Edge go to edge://gpu, and search for HDCP 2.2, you should be able to see it’s shown as true.

Once you completed all these steps, use Edge to open Netflix, and search a video, for example, Stranger Things, you should be able to see HDR logo. Once you start streaming it, press CRTL+ALT+SHIFT+S, then you should be able to see video resolution is 3440*1440. If you still see 1920*1080, then it means your video is still in 1080p.
