Hello Satish. Would you please delete three of your four posts. Someone will reply to the last one in due course.
Duplicate posts have been deleted, this will be the main post.
Reguarding this question it almost sounds as if the Satish may be trying to connect the LCD to their Serial port. If this is the case you will not be able to do this, the LCD or any display is only going to connect to the Video port (VGA/SVGA/Etc.) If you're trying to connect a Apple or other type of monitor that is not a IBM compatible monitor you will need to purchase an adapter from the LCD manufacturer (if compatible).
