Adding a display over network !

You are doomed if your laptop has only one HDMI Port & you are running Linux in that box.

Unlike windows – where there are tons of easy to run solution, & there are still tons of solutions if you have big numbers in your pocket.

Certainly – I neither wish to spend money on external VGA/HDMI extender or docking station nor to change OS. So after googling a lot I discovered a solution which utilized a different machine to act as the streaming client. You can use RPI or an old p4 machine.

Below is how it works.

  1. Adds a virtual display on your machine, usually all graphics card support at least one virtual display.  You do all this using xrandr
  2. Create a VNC Server to stream that display – but since you cannot each time run two commands just to connect display – we are running VNCViewer in listen mode
  3. Connect to vnc viewer & keep running it in the background.

You Laptop —[Display Data]—> Network —-> VNCViewer

As suggested above you data is being streamed over the network  – you cannot run 4k data. But if you have good Lan speed you won’t face any problem.

I have also optimized settings for best experience – so far I can use terminal, watch videos – the only drawback is you feel the lag when you use keyboard or mouse for realtime feedback.

In Client Machine, i.e. your laptop.

You will need to install x11vnc & screen

In server Machine (LAN address 10.0.0.2)

You will need to install VNC Viewer in client side.
