Just to start i never used this before, but seeing how my laptop can use extend screen feature, i would like to purchase one, but i want a reliable one. The thing i would not want is spending too much money. But that probably seem impossible. Having 5G connection, HDCP (So i can watch netflix or other copyright content) less delay as possible so is okay to play games with, and maybe widi, other such things. I dunno if i need a network connection instead of direct connection. I dunno if it makes a difference but i want best experience possible. I was looking for one and found too many with either more bad reviews than good, or not many reviews at all to help make it less suspicious. There many cheap ones from china, and past experience buying stuff from Chinese sellers is bad.
