My brand new AMD Radeon RX 7900 XTX 24 will not send video to Ports 2 and 3. The monitors are not displaying as connected in Device Manager. In addition, Port 1 will drive one monitor but does not recognize the other two monitors. If I connect Monitor 1 to either port 2 or 3, there is no signal. When monitor 1 is connected to port 1, the mouse, app windows and utilities act like there are three working monitors. For example, Google Chrome opens by default in Monitor 2 when the three are running. Although there is no video on Monitor 2 and it doesn't show on Device Manager, Google opened on that monitor but does not display.
