Thought i post here rather than the general porn section but i thought about upscaling my porn to 4k for better quality especially for the old pre hd ones. I know there are some expensive ones online to do this but for someone like me i can't tell the difference in quality.

I've just been using the free ones online to mess about with lil clips and pictures etc and i don't notice anything and i'm not sure why. Is it cause it's a cheap online one or something else .

I also spotted 2 types one being normal upscale and the other AI upscale? Whats the difference and using this as a focus point example what looks more pleasing to the eye. Hope using Ava Addams helps do it justice etc

Normal Upscale

AI Upscale

Her body looks amazing and meaty but again in terms of 4k upscale quality what shows it off better

Hope those who are quite tech savvy can tell the difference and point out what to look for
