I have a Sony Bravia tv and want to stream netflix from the computer but they always show up blank when i use the cable to connect them. Do i need to alter the properties on the computer or something?
 
Yeah, it might be on the function keys or in the control pannel but you have to turn the secondary moniter "on" or the output on.
