XPS 7390 HDCP not compatible anymore but it used to be

Question

I used to be able to play Dolby Vision and HDR videos in the Netflix app on my XPS 7390.  Now, when I try to play them, I get Error code: U7361-1253-8004CD22.  Normal HD videos will play just fine.  I checked my Intel Graphics settings and it says it's not HDCP Compatible, but I know it used to be.  What changed?  I tried reinstalling the drivers.  Still won't work.  Anyone else having this issue that fixed it?

Thanks. I actually figured that out some time ago but I don’t think I should have to plug my laptop into a tv every time I want to use Netflix 4K content. Hopefully there is a real fix soon.

I had the same issue as you. I found the solution on Reddit. First make sure you have HEVC extensions installed/updated from the Microsoft store. Connect your laptop to a monitor/TV using the HDMI cable and then open Netflix. Then disconnect the cable and Netflix should start playing 4K content again.  Hopefully, this solution works for you as well.

Yeah, I just noticed today that it reverts back to the error messages when I restarted my laptop. Incredible.

It would be nice if a solution could be found for that soon. I also have had this problem for the past couple of months and made numerous Reddit posts, without any actual solution. Forcing the app to use the external GPU (1650Ti mobile), gets rid of the error, but also caps the video to HD.

If anyone is still wondering, I resolved this issue by changing the refresh rate in my laptop display settings to 48.000Hz.  It was set to 59.997Hz before.  It works perfectly now that I changed it.
