I have the same even though the images are fine. It is really the oculus that adds the fully black line. Only way that I know of to hide it is by having an image where the seam is supposed to be black. Pretty basic functionality for a VR headset. Hope this gets priority in fixing. Should not be too difficult since there is lots of video content that plays without a visible black line.
Hi I'm having the same problem with this new bought VR headset.
Before with my Oculus GO, and the Oculus gallery app I have never experienced this.
It's quite annoying, as we do use this headset for professional prsentations with 3D renderings for our clients.
Any other free an good possibilities?
