Not possible. The U2421E does not have the DPBS (Dell Power Button Sync) feature. The U2722DE USB Type-C is the only monitor currently that has that feature and it only works with OptiPlex 7090/3090 Ultra platforms.
@dellchacha On my XPS 13 9350, there's a BIOS option called "Wake on Dell USB-C docking station" that causes the system to wake up when connected to a Dell USB-C docking station. The same behavior might occur with a Dell USB-C display, since it's essentially a display with a built-in dock. However, if you have a system that's shut down but already connected to the display and simply want to power it up, I don't think that's available. And come to think of it, I guess that's a rather surprising omission given that the latest generation of Dell USB-C displays that provide Ethernet otherwise seem to be full replacements for docking stations, at least for lower-end setups that don't require things like Thunderbolt.
