I've encountered a strange problem. I have an Acer V247YBI IPS LED monitor attached to my Dell notebook via HDMI. It is working fine, but every time I try to start a Netflix or an HBOGo video the monitor losing the signal. If I unplug and replug it, then it works for that one video, but for the next video it is black screen again. Never experienced anything like this. Any ideas why this is happening?
