If I switch on monitor first then switch on raspberry pi, it works fine. But if I switch on raspberry pi and then monitor or switch on both pi and monitor simultaneously no display is shown on monitor.

** I use age old hp v194 18.5 inch monitor with a HDMI to vga converter.

I had the exact same problem. Solutions are:

  1. Turn on the screen first. I give it 4 seconds. Slower SD cards won't have this problem, since the Pi waits longer before checking for a monitor.
  2. Add/uncomment hdmi_force_hotplug=1 in /boot/config.txt.
  3. Turn off OpenGL. sudo raspi-config --> Advanced Options --> GL Driver --> G1 Legacy.
  4. Get a HDMI screen.
