External monitor turning off and on
I have a precision 3551 from work and it's been working great. I hooked up an external display via HDMI. I have to follow some udemy courses for work and when I start a video or pause a video it will randomly turn off, display no signal, and go back on again having moved all applications to the laptop's display. I have tried to make the nvidia card the main card to use, but seemingly nothing works. The only thing that changed is that before I changed the card it would turn off stay on no signal until I turned off my laptop, unplugged the monitor, turned back on the laptop and after it was on plug back in the display and it worked again.
Anyone know what I can try, or a possible fix.
Any help would be appreciated.
