You are doomed if your laptop has only one HDMI Port & you\u00a0are running Linux\u00a0in that box.<\/p>\n

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.<\/p>\n

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.<\/p>\n

Below is how it works.<\/p>\n

    \n
  1. Adds a virtual display on your machine, usually all graphics card support at least one virtual display. \u00a0You do all this using xrandr<\/code><\/li>\n
  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<\/code> in listen mode<\/code><\/li>\n
  3. Connect to vnc viewer & keep running it in the background.<\/li>\n<\/ol>\n

    You Laptop —[Display Data]—> Network —-> VNCViewer<\/p>\n

    As suggested above you data is being streamed over the network \u00a0– you cannot run 4k data. But if you have good Lan speed you won’t face any problem.<\/p>\n

    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.<\/p>\n

    In Client Machine, i.e. your laptop.<\/strong><\/p>\n

    You will need to install x11vnc & screen<\/p>\n

    #!\/bin\/bash\r\n#Run VNC server in remote device. 10.0.0.2 is my machine which has monitor connected.\r\nssh  root@10.0.0.2 \"nohup \/root\/vncserver.sh > \/dev\/null 2>&1 &\"\r\nxrandr --addmode VIRTUAL1 1920x1080\r\nxrandr --output VIRTUAL1 --mode 1920x1080 --right-of eDP1 # find your main display\r\nscreen -X -S vnc quit\r\nkillall x11vnc\r\n# adjust postion 1920x1080+3511+180, i.e. 3511+180 accordingly\r\n# i have different resultion display so had to move.\r\nscreen -dmS vnc  x11vnc -connect 10.0.0.2:5500  -display :0 -clip 1920x1080+3511+180 -wirecopyrect  -viewonly --nossl -ncache 10 -ncache_cr\r\n<\/pre>\n
    In server Machine (LAN address 10.0.0.2)<\/strong><\/p>\n
    if [[ $(ps -ef | grep -c vncviewer)  -ne 1 ]];\r\nthen\r\n    echo \"Running\"\r\nelse\r\n   export DISPLAY=:0.0;\r\n    vncviewer -listen 0 -fullscreen -owncmap -viewonly;\r\nfi\r\n<\/pre>\n
    You will need to install VNC Viewer in client side.<\/p>\n","protected":false},"excerpt":{"rendered":"
