How to connect more than one monitor to a laptop?

Question

Monitors

Good day. Faced a problem. There is a laptop, a monitor is connected to it via VGA, everything works fine. There is also HDMI. I connect another monitor through an adapter. It turns out a laptop + vga + hdmi. Both on linux and windows, the third monitor is detected, but the black screen is on, it is also black in the settings, there is nothing on the monitor and only two that were connected before work. laptop + one of the connected. Is it possible to connect more than one additional monitor to a laptop?

Answer 1

The problem is in the video card, it can only work with two monitors at the same time, if you turn off the monitor of the laptop itself programmatically, then 2 connected ones will work, but if all 3 screens are needed, then the issue can be solved either by installing an external video card or by installing a usb adapter on the monitor, looking what do you want to do with this monitor, usb is enough for work, for games and movies in high resolution you need a video card.

Answer 2

I connect another monitor through an adapter

What adapter? What monitor? Which monitor input?
How does it behave if you disconnect the monitor from VGA?
Find a monitor with HDMI - and you will be happy!!!

Answer 3

2 displays are the maximum capabilities of old video cards (and with a VGA port, the video card is definitely old), find the docks for the video card, everything is written there. In general, rico has already written everything, you need another monitor, connect an additional video card via USB or miniPCI-e if the ports are divorced.
Another option is to buy a thin client and output video via Ethernet cable via RDP, but there will be lags (although lags will be everywhere)
