Question about Apple MacBook Air – Late 2020

The Apple Macbook Air 2020 has an M1 processor, but as far as I know it can only be used with an external display. With such a dual screen solution, I would definitely switch to a high-resolution 4K UHD display.

A very cost-effective solution would be this screen, for example, because it offers a 4K 3840x2160 pixel resolution and also a USB-C port, so that the Macbook can be charged at the same time. It's available in black, but perhaps a white model would also suit the Mac?

Samsung Smart Monitor M7 S32BM701UU (3840 x 2160 Pixels, 32 ")

1 x 32 inches takes up much less space on the table than, say, 2 x 24 inches with 1920x1080 pixels and a 4K 3840x2160 pixel screen would be able to use twice the number of pixels, so you would see twice as much content in less space.
