I noticed that when my dell inspiron 15 running windows 10 is plugged in recently the colors will disappear from any video I watch. If I unplug, then the color returns instantly. Plug back in, the color disappears instantly. It looks like black and white almost. I tried plugging my laptop into another outlet, but the same thing happened. Please don't say motherboard because I had that replaced by dell about 2 months ago. What is going on? Thank you.
