lspci was just so I could see the full hardware listing of what your laptop had, it will not tell you which is being used, since they're both seen by your OS at all times.
timothy brings up a good point. this is os agnostic hardware related. so from a cold boot do you you see the manufacturers splash screen or even the grub menu on the tv (before the os is launched) ? if not there mite be something in the bios that has to be toggled.

other than that i would try a different tv, cable and laptop to isolate which is faulty.

HI thanks. From boot I can't see absolutely anything on the tv, everything is on my screen. The thing is, it works absolutely fine in windows (my laptop is dual boot) but not at all from ubuntu. So,I assume there is nothing I could toggle in the bios if it works already (only) in windows?
