Ask HN: Best monitor setup for online presentations?

Hi folks, those of you that do lots of online presentations - what monitor setup would you recommend?

I need to be able to see the video feeds (gallery) of meeting attendees, whilst doing a screen share presentation of my slide show, whilst also being able to see the next slide of my presentation.

Quite flexible with my budget, but before I invest in a monitor or two, I was hoping to first get some advice or recommendations from y’all.

Thanks!
