I have a Sony Vaio laptop which screen had broken. I just upgrade the windows from win7 to win10. Since the installation comes to restart, the ext monitor(my tv) had no signal. I know the installation has completed but i can't see the screen or anything because i had chosen clean install so the drivers were all gone. Is there any method to make the screen shows on the tv through vga cable with fresh installed win10(not yet configured)?Pls help
