i have seen many 80-90s movies on Blue-ray and i know that Blue-Ray movies are either 720p or 1080p, so the question is how is it possible to make thrm to HD (or look like HD) i suppose back in 90s there wasn't High Definition
If you take a blurry picture and convert it to 1080p, it's still just a blurry picture in 1080p. Putting an 80s or 90s resolution movie just means it's 80s-90s resolution in 1080p format.
