I have a 3rd monitor (dell UltraSharp) I use for a live feed out of Resolve and screenshare that. I tried the above recommendation for discord, which I find has better color quality. However, if you upgrade to nitro, you can output HD. Downside, Client needs to upgrade as well to actually view in HD.
With the deck link, are the clients able to view the higher rez or they are seeing the mpg version of it. I guess it depends if they are using the paid Zoom, no?
