Is there a way to run more than two external monitors (without display link, which I find to be too finicky) on one of these by using 1080p monitors. If the machine will support two external 4k monitors, would it support 3-4 1080p monitors or am I bottle necked by a TB3 controller? I’m assuming there are two controllers (one for each port) or am I wrong?

I need the extra monitors for necessary, non-graphics intensive apps that are critical for workflow, and I need 27” for the screen space.

Otherwise, I’m stuck using a mini with a egpu for four monitors and and one more screen hooked into the mini. Given the gpu shortage/price gouging, the mini’s issues (i have one at home a like it but admit the connection issues are real) and older processors, I want to avoid the mini.

I wanted to stick with an iMac since I suspect it will receive support longer, I can upgrade the memory more easily than the mini, and because the multi-threading will help when I’m dealing with all sorts of crap I need to have running at once (browser with several tabs, acrobat editor with multiple large docs, word with multiple docs, outlook for mail and calendar, teams, ip phone, zoom, excel with some rather large files, large videos that I sometimes need to edit for exhibit purposes, iMessage, and at least one virtual machine or Remote Desktop access) without bogging the machine down.
 
I don't believe there is a way. Depending on GPU the 2020 iMac will support either up to two additional 4K or 6K displays. Using more than a total of three displays will require the use of DisplayLink. The bottleneck isn't the TB3 controller but rather the GPU itself.
