In a laptop the hdmi plug on the side is the only way out. Respectively only outputs are hdmi on a desktop.

When you have two monitors and two graphics cards (as in a desktop one on the motherboard and one additional) then the connection is simple. Connect each monitor on one of the graphics cards. But if you only have one graphics card, such as the motherboard in a laptop, then if you want to connect a second monitor to it you will have to use a KVM switch (Keyboard - Video - Mouse).

A KVM switch is a physical switch that you can turn to switch your system to another network. For example, in the old days, you might have to turn on such a switch to connect your system to a non-network printer.


Similarly, to use your laptop as a second screen, you can do it with KVM software. You install the software on your desktop and laptop and the local network creates a bridge between the two devices.

You can control your desktop and laptop with a single keyboard and mouse, turning your laptop into a second screen. Prerequisite, deskop and laptop to be at same network.

Note that while on a dual monitor machine one monitor works as an extension of the other, on KVM systems you cannot drag and drop an active window from one monitor to the other. It doesn't work that way. However, some they allow you to drag and drop one to open it on the laptop you are using as a second monitor.

It's not quite the same as two screens on one machine, but it's better than nothing and often faster than using a cloud drive (and especially a flash drive ). Και εν γένη, αν δεν έχετε χρήματα για την αγορά μίας δεύτερης οθόνης, τότε η a free KVM software is a good solution.

In fact the whole system consists of two (or more) computers running and you can transfer files from one computer to another and work on both at the same time, with a common keyboard. If you coordinate your tasks the system can work as if you had a second screen.
