ELI5: How do screens smoothly scale resolutions that aren't multiples of each other? E.g. playing 1080p or 720p video on a 900p screen, or reducing my phone's resolution from 1440p to 1080p?

There are complex algorithms that will combine pixels with their neighbors in certain ways. If you have a higher resolution screen being scaled down such that a pixel should be 70% one color and 30% a different color, the calculation would yield a combined color of the appropriate proportions.
