From what I can find on this monitor online, the HDMI port on the monitor is HDMI 1.4. You're limited by the lesser port between the video card and the monitor. HDMI 1.4 can do up to 144 at 1080P, but this can be further limited by the manufacturer. It should be able to run up to 4 monitors at the supported specifications. How well it'll run whatever you're doing is another matter. If we're doing triple display setup for iRacing, that might be rough on a GTX 1650.
I'm going to point you towards this monitor: https://www.microcenter.com/product/614584/asus-vg27vq-27-full-hd-(1920-x-1080)-165hz-curved-screen-gaming-monitor
It clearly states in the specifications it is HDMI 2.0 and that it supports up to 165Hz via HDMI.
