Set higher resolution than screen?

My laptop has full HD, that should be 1920x1080p. Now does it make sense to play games at a higher resolution? Regardless of whether I set a higher resolution, the maximum possible resolution should be 1920x1080p?

You can only play with Full HD or worse. But I don't understand the question.

Correct, full HD means 1920 × 1080 screen points.

With so-called "downsampling", games can actually be rendered internally by the graphics card with a higher number of pixels than the screen has pixels. At the graphics output, the card will still output 1920 × 1080 pixels for the screen.

To do this, however, you would first have to fool Windows into a fictitious screen with more pixels than it actually has, and the graphics card itself has to support this.

Downsampling can help as a kind of full-screen anti-aliasing in games that do not offer (higher-quality) full-screen smoothing by themselves. The game itself must then also offer the higher resolution modes.

Of course, downsampling also costs additional rendering performance from the graphics card.

Hmm… That means that by rendering with a higher number of pixels, a better quality can be achieved…

I haven't tried it, but as Paroto92 has already written, I have in my head that even though you e.g. Only a full HD screen can set higher resolution in games. And my question was whether it would be useful to play with a higher resolution setting, because in the end my screen only shows full HD.

In a game like GTA IV, this was definitely the case with regard to real full-screen smoothing, as it more or less only offered anti-aliasing, but the options for the textures themselves were quite limited.

However, it remains a double-edged sword, because downsampling on the one hand requires more graphics performance, but on the other hand does not deliver the same quality as on a monitor of the same size with a physically correspondingly higher pixel density as on your notebook screen.

Yes, but what he wrote can't work at all, if your monitor only has a certain number of pixels then it can't simply (is now exaggerated) display 4 k. This is not possible from the point of view of the pixels.
