Screen goes black when sharing PowerPoint
I've been having an issue where my screen will flicker and then go black whenever I'm sharing a PowerPoint. The laptop stays on and so does the Zoom meeting. Those in the meeting room can still see me but I can't see them or anything that's happening on my screen. When I try locking my screen, it appears to go back to normal but that I notice that the visuals on my screen flicker and get grainy. The problem continues until I somehow manage to stop screen sharing. It's happened a few times already and somehow only whenever I'm about 1 hour into a meeting. I've searched online and everyone seems to point towards the nvidia graphics card, but I only have the Intel graphics on my laptop. I don't have an additional nvidia card. Totally clueless as to what's causing this and completely annoyed too. Hope someone can help me out =(
