2k/4k

[Acer2010]

I expect you all get tired of me talking about restorations; for that, I apologize. All I have to ask any of you is this: Who is good at telling the difference between a 2K and 4K restoration which can be the source of a 1080p standard Blu-ray?

If anyone is an expert at this sort of thing, please let me know. Thank you.
