Reply to comment by TheLuminary in ELI5: how does rendering a video game resolution above your monitor resolution make the picture more crisp? by ItsSnowingOutside

Why doesn’t the game itself say the pixel should be gray instead of black or white? If the game renders in vectors, I’m assuming it can average for a specific resolution.

The game does.... But it uses these techniques to do it. That's why you have lots of antialiasing options, including super sampling.

Rendering higher resolution for your display, but turning anti aliasing off. Is just kind of manually doing what is built in

It can, but some now common graphical special effects and lighting techniques don't work because they need to know which pixel belongs to exactly which object on screen, while that gray pixel is part of both the black and the white object.

It's kind of complex, but generally thought the overall look with those effects without antialiasing is better than without the effects but with antialiasing.

There are workarounds that give something similar to real antialiasing that work with those effects, or if you have lots of GPU power but a low res monitor you can do what OP asks and Renee a larger screen that you realize down.
