VGA to Monitor signal lost cannot connect

I am getting signal lost when I connect laptop to external monitor through VGA cable. I have tried FN+F3 to switch and it just makes my laptop monitor black and the tv still signal lost.
I tried making resolution smallest and restarted, same result.
I tried going into windows setting and driver setting to output the external monitor or extend monitor, no result.
I tried the cable, it's ok, I used another laptop on the TV, it worked.
When I go into windows settings to see the monitor list, it shows me the same monitor name twice (name of laptop monitor).
Do you have any hints for me ? Could it be a driver issue ? Let me know is you need extra details.Thanks.
