Bought ViewSonic 2719-sh 27 inch monitor few days ago, I'm using it with PS4. When I plug headphones in the monitor's audio out, right phone makes noise but when I insert the jack only half way in then the volume lowers a little but the noise disappears. Same headphones work fine with my laptop and phone. I've yet to try another headphone, perhaps speakers with external power source. I was wondering what you guys think, could it be faulty audio out port, should I take it for replacement?
