Reply to comment by BaLance_95 in ELI5: how does rendering a video game resolution above your monitor resolution make the picture more crisp? by ItsSnowingOutside
Assuming the time between frames are constant; there is no advantage. Having the GPU output more frames than the monitor can show, just means the monitor will ignore the extra frames. The GPU will do more work and heat your room up faster. So if your room is chilly it might be an advantage, depending what other kind of heating you are using. Most games have a frame limit, vsync or freesync setting, which in their own ways will limit the frame rate to something appropriate.

That's fundamentally wrong. More frames and the information displayed on your screen will be newer.
For the sake of simplicity, let's say you had 1hz screen and GPU producing 1fps. By the time a frame would appear on your screen, it's already 1 second old. You get to see the frame that was generated 1 second ago.
Now, if you had 4fps, the frame you see would only be 0.25 seconds old.
Linus had a video a while back, comparing 60hz and 60fps vs 60hz and 240fps. The difference is MASSIVE.

I think in your second example you would have horrendous screen tearing

With a 1hz screen, screen tearing would be the least of your problems:)
