I have an HDMI to VGA connector and a Samsung LED screen. The screen is fine, the VGA cable is fine, the connector is fine (tried with different laptops running Ubuntu and Windows).

The Problem: I'm plugging the HDMI-VGA connector in my Macbook Pro 2015 but the display doesn't show on the external screen.

What I've tried: I went in Displays and tried all given options like extend screen and more. The window also shows the name of the screen "SMB2230" on my Macbook and when I plug-in the HDMI, the screen flickers for a second and dock (on the right) disappears from the built-in display and I can move my mouse to the right and it also disappears but the external monitor shows the message "Check signal cable". I have tried restarting it as well but no luck.

Note: The screen is working with other laptops running Windows and Ubuntu with the same connector and the same VGA cable.

Please don't tell me that I have to use MiniDisplay port/wire from Apple.

Try a PRAM and SMC reset. Usually helps.

Also try replugging in the connectors on both ends

  • Thanks for the answer, tried it but still no luck. – Robot Boy Mar 1 '16 at 19:45
  • Could be a driver problem – user173581 Mar 2 '16 at 3:24
