Is it possible to connect LCD,TV, or any electronic devices with computer parallel ports?

Not that I know of. Generally peripheral devices connect via serial or USB connections. TV and TV monitors connect via VGA or DVI.

Glad you could help somewhat Scott. I got a PM and had no idea what this was. If it is not about IVs (not TVs) I haven't a clue.

OK I just had to look.
The answer is NO to monitors but YES to some other devices, to an extent namely older lagacy devices.

Have a look here for a more detailed explaination: How Stuff works
