Because my monitor has no HDMI connection and my laptop is not one for this cable.
Can you do.
Only works then not synonymous.
Buy a VGA HDMI adapter.
Aha. For THIS cable… And now we should know what that cable is?
First of all: No, you can't solder a HDMI head to it.
You can certainly buy an adapter if you know what your monitor and your computer have for a connection.
Rather "HDMI => VGA", I suspect… Because the monitor probably has no HDMI.
