I have updated the chart.

I do not want to recommend particular resize methods or go into the subjective differences between them. The bar graphs in madVR already do a good job of that. The reason it might look messy on a mobile device is only because it uses bilinear, nearest neighbor, or similar which are also options in madVR.

Resizing methods are not codecs. Codec is short for "coder decoder" and usually referrers to software which codes images, video, or audio in a different format like JPEG, H.264, or MP3 and can then decode it back to the original format.

No. Imagine you start with an image at 3840x2160. You scale it down to 1920x1080. Now you want to upscale it so it looks as much like the original 3840x2160 image as it can. Nearest neighbor does not get very close. You want it to look as if it was the same content but at 2x the resolution, you do not want to represent the lower resolution source perfectly.

Also it is 2x the resolution, not 4x. 4x would be 8K or 7680x4320. A scaling factor of 1.414213562393095 is not a 2x upscale.

Image doubling generates 4 times the number of pixels. Image quadrupling generates 16 times the number of pixels.

I think I'm a layman and it's not oversimplified to me. Each bubble is an entry point to a discussion.

I want to collect feedback on it for a bit before adding it to the end of the first post.
