Let’s say I would like to use two external monitors and my laptop has only one port. Is there any hardware device that I can plug these two monitors in, and it would have one port going to the computer behaving as a single monitor from the computer’s perspective?
I realize that there is the question of how the two monitors will be “combined”. The two simplest ways that come to my mind are:
- The device literally slices the image coming from the PC into two halves, then sends the left half to the monitor plugged in at port 1, and sends the right half to port 2. All maximized windows span both monitors, without the PC realizing it.
- The device somehow presents two screens to the PC, which the PC treats as two monitors. Windows can only be maximized on one monitor, there is no easy way to make them span (disregarding special software like Wayland).
Either of these would be good enough for my purposes. Is there such a device and what is it called?
To be clear, I am asking about simultaneous, non-identical output to both monitors. So not a KVM switch or simply duplicating the same exact image across two monitors.
