Yeah, I don't understand why everyone is trying to invalidate their experience or suggest workarounds (implying that they are the problem); this isn't stackoverflow.
Every TV I have interacted with in recent years is slow and terrible, except for really old ones. The TVs are the problem, and we shouldn't be making excuses for that.
I've had the most success doing 3d scanning with Heges. The LiDAR works pretty well for large objects (like cars), but you can also use the Face ID depth camera to capture smaller objects.
I did end up getting the Creality Ferret SE (via TikTok for like $100) for scanning small objects, and it's amazing.
I did a test scan on a small object (1:12 scale doll), and it seems to capture fine details really well, but I can't say for sure that it would be suitable for things like car parts; you would have to try it and see I suppose.
