How can I make the zoom recordings the highest resolution possible?

hi, Atep

So you want to record your video in high resolution?
Are you setting up a meeting and turning on HD video?

If you want to increase the resolution of the shared screen, it is better to remove the cause of the low resolution.
1. Don't check "Optimize for vide clip" when you share screen
2. If your own display is low resolution, use a high resolution display ex)1,920x1,080.
