Connecting second monitor with VGA/cat 5 cable [Closed]

 Blocked Profile -
I have bought two VGA connectors that are supposed to connect my second monitor using Cat 5/6 cable. When these are plugged in the Laptop main screen shuts down. I normally use a 5ft VGA cable but want to use a longer cable so that it can be tidy. is there some tick box that I have not seen to correct this problem?

What Operating system? You should be able to press WINDWOS+p and select what display configuration you want.
