I think those screens are probably just fine. I don’t see any sunspots, which would be actual damage to the LCD screen itself.
The optics on these goggles have to pull off a pretty tough trick. You only get good focus when your eyes are lined up perfectly and the right distance away from the screens. Not everyone’s eyes are the same distance apart. I have HD1’s which have an even wider FOV than the HD3’s and I find that if they shift even a milimeter off-center, I lose a bit of focus.
Consequently, it’s tough to get a perfectly-focused photo of the LCD’s. The seller did a pretty good job of capturing a decent image. I’ve seen a lot worse.
