There is no display while connecting laptop to a HDTV or PROJECTOR

I try to connect my laptop to a HDTV either through HDMI and VGA but it doesn't work. There is no signal on my TV.

I've tried to look for the option called "connect to a projector" from "display" in control panel but there is no such option in display.

You are missing the graphics driver. Please check the display drivers in your Device Manager. Download the appropriate display drivers for your laptop
