HDMI keeps losing signal and the display image is grainy.

Connected my Nitro 5 to an hdmi and the 2nd display is not being detected or shown by the multiple display settings for both nvidia and intel as well as the windows display settings. The projector shows a very grainy, basic colors display for a while and keeps resetting. I know it a weird problem but there was not problem with my friends laptop when he connected to the same cable.
