The HDMI output port on the Raspberry Pi is compatible with the HDMI port of most modern TVs and computer monitors.

Raspberry Pi 4 works with either a micro HDMI-to-HDMI cable, or a standard HDMI-to-HDMI cable plus a micro HDMI-to-HDMI adapter, to connect to a screen. Raspberry Pi 1, 2, and 3 use a standard HDMI-to-HDMI cable.

When you get a No signal error or Missing HDMI output message on the monitor, it means that there’s a problem with the cable connection, the SD card, or the power source.

Assuming that the cable is OK (meaning it works when connecting another device and your monitor), see below some solutions that proved successful.

  3. Use a shorter or better quality HDMI cable.
  4. Make sure your device’s power supply delivers 1A, not less.
  5. Remove the SD card and reboot.

  2. Open the boot/config.txt files with a compatible reader (nano or vi)

    • #hdmi_force_hotplug=1
    • #hdmi_drive=2
  4. Remove the at the beginning of each line
  5. Save and remove the SD card
  6. Mount the card in the Raspberry Pi and the monitor should work.

If you’re using a classic monitor, not a TV monitor, you can leave out the line hdmi_drive=2.

Additionally, if the above steps didn’t work, repeat them, also removing the # from the following line: #hdmi_safe=1. This is only an alternative, as this might also affect the display quality.

This second solution can also be done directly on the Raspberry Pi, but you have to connect to the device via SSH. The modifications are the same.
