Dual Display support for MacBook Pro 2019

I have a 2019 MacBook Pro (Radeon Pro 555x 4 GB, Intel UHD Graphics 630 1536 MB) and am having trouble connecting two external displays to it. One of the displays is an Apple Studio display, and the other an LG 4k 27". Separately, they work. Together, they do not. I have tried many different ways and cannot get them to work together. So as of right now, i am only using the studio display. I am guessing the MacBook just doesn't support two external displays? Can someone confirm this for me, Thanks!

MacBook Pro (2017 – 2020)

up to TWO 5K displays. MORE if using only 4K displays.

ONE 5K display to a Thunderbolt port, and one to a SIDE as well, because they likely share a Thunderbolt controller on each side, and you need both controllers for this enormous data rate.

More recent versions of MacOS are far less tolerant of data transmission errors when sending data to displays.

Please describe what cables you are using, how long those cables are, and how you are connecting everything together.

After doing a bit more research, apparently its either ONE 5k studio display or TWO 4k displays. I believe that is where the problem lies for me. So for now, i think ill just use the 5k display until i figure something else out or upgrade my 2019 MacBook Pro.

google lol. Well either way, that method is not working for me. However, i tried connecting the two displays to a newer MacBook Pro, and it worked first try.
