Ok, richman. I can afford a desk for 80 euros, anything more than this is a not justified purchase.
Yeah, there are industries where a 40-inch monitor would be needed, like at airports with hundreds of flights each day, but that is not very usual, especially in smaller countries/towns/cities.
Swealp, it isn't clear but are you definately running those screens at 4k and using dpi scaling in the OS?
