Can I run TWO ext. displays on 27" iMac (2019)?

re: iMac19,1 (model # A2115); Retina 5K, 27-inch; macOS Monterey 12.0.1…

I'm already running ONE additional, external 4K display (Samsung 28-Inch U28D590D), via a Thunderbolt port, using a USB-C-to-HDMI adapter (60 Hz).

It works great!

So… The iMac has TWO Thunderbolt (USB-C) ports, so… can I add another, identical adapter, with another, identical 4K display – giving me THREE screens?

Many thanks.

iMac 27″, macOS 12.0

yes, you can run two displays but your resolution is lowered to power the GPU across them
