4K low vs high quality textures?

Question

Monitors

Hello?

As you know, on PC games there are game graphics settings. On consoles, there are no such graphics settings, but the quality of the picture (on consoles) depends on the screen resolution. Let's say that I have a 4k monitor on consoles, the picture quality is, of course, very good. But the following question arose: If you put on a PC (4K monitor!) The quality of the textures is low and high, how much will the picture differ?

PS It is logical that with high quality textures the picture is better, but why can't you choose the texture quality level on consoles?
