When you plug in the HDMI cable do you hear a sound from the laptop? When a new device is recognized by the OS it makes a noise. Same thing when you unplug it.
Hi! Sorry about not mentioning earlier. My laptop has only a mini display port that connects vga. it is 3 in 1connector for acer laptops. This connector was checked and is working great. I went to a place to have the connector checked with a newly opened laptop thats like mine.
My laptop does detect another external monitor. But theres no signal going to the external monitor or projector... since its just black on the screen of the external.
