I have a cheap hand. I clicked to turn off the mirror, but the display on the secondary screen cannot be restored?

Dual-screen display, the secondary screen does not display, I clicked on the upper right corner to close the operation, and I couldn't restore it even if I replugged the monitor Action tried: * Find Settings-> Display-> Press and hold Option to detect the display, nothing happens * Both monitors can be displayed normally when displayed separately, but the other secondary screen cannot be displayed at the same time. Interface Settings for Display * Interface unplugging * I tried to restart the system, but it cannot be solved Ask an expert for advice.
