Problem wIth mac
Hello,
I am using DELL P2723D and an I-tech device. My macbook pro is late 2016 with i-5 processor. I trying to watch Udemy courses, but most of the videos can not be seen. The voice of the video is coming, but I can't see the video. I have no idea why this is happening. When I tried several other browsers, the problem still appears. When I don't use the display, the video works perfectly. I couldn't find a way to solve the issue. If anyone help, i will be very happy. Thanks.
