video hardware issue

[minudome]

Hello Community,

during a meeting today, the screen became black. When restored (automatically) some images like icons and the desktop were blurred (in my laptop, not only in Zoom). Not all the text like the clock and the icons' names were clear, as if a shortage of pixels came into place. After the Zoom, all ok. 

Could someone help me with that and how to prevent it?

Thanks,
