Can you play video out of a 9 pin serial port

According to a quick check on Dell's website - there are no video outputs on the Dell Inspiron 19.

The 9 pin serial port is for old printers/modems, and would not provide nearly enough bandwidth for video.

Also it appears to be non-upgradeable since it is an AIO desktop. You will not be able to get video out on this AIO desktop.

It cost 80 bucks and it may or may not be worth it depending on what you want it for.

Thats all i can think of. Im not sure if it works well or not, so don't take my word.

Note:Even USB2 has limited bandwidth for video output.
