I just got an LG OLED CX and hooked up my Xbox Series X using the HDMI 2.1 port, hoping to stream Netflix in 4K HDR smoothly. However, the Netflix app on my Xbox keeps defaulting to 1080p, even though all other apps like Disney+ and Prime Video stream in 4K just fine. I’ve double-checked that my Netflix plan supports 4K, and my internet speed is more than enough (200 Mbps). I updated the Xbox firmware and the TV’s software, tried different HDMI cables rated for 2.1, and enabled all the UHD settings on both devices. Still, no luck with Netflix 4K. Interestingly, when I cast Netflix directly from my phone to the TV, it does play 4K just fine. Has anyone experienced Netflix stuck at 1080p on Xbox Series X with LG OLEDs? Could this be an Xbox app issue or something with HDCP settings? What else can I try to get proper 4K streaming on Netflix via the Xbox setup?

It’s pretty strange that Netflix alone is stuck at 1080p while other apps stream 4K just fine on your Xbox Series X. Since you’ve already updated firmware and tried different HDMI cables, I’d double-check the Xbox’s video output settings specifically for apps. Sometimes the Xbox can limit app resolution independently from the general display settings.

Also, you mentioned HDCP - Netflix requires HDCP 2.2 for 4K playback, so make sure that’s enabled on both the Xbox and your LG OLED CX. A quick way to test is to try playing a 4K Netflix title on the Xbox and then check the TV’s info menu to see what resolution and HDCP version it’s receiving. If it’s stuck on HDCP 1.4 or 1080p, that’s probably the culprit.

One more thing: some users have reported that uninstalling and reinstalling the Netflix app on Xbox can reset any weird
