AMD Raedon RX 7900 XT
Driver Version: 31.0.23013.1023
ASRock z490 itx/tb3
Latest firmware, drivers up to date
I use the RX 7900 XT to drive and power a USB C monitor. It is my main display in Windows. 2nd Monitor connected via DisplayPort.
Any power cycle POSTS and boots through the DisplayPort monitor all the way to Windows sign in. It is not until I unplug and replug in my USB C monitor that it powers back up and becomes the main display again.
In certain situations like bench testing I only use my USB C monitor so no display after power on seems kind of odd. I have not tried powering it from an external source, yet. I would rather avoid the extra cable on my desk and the monitor cycles like it is getting power.
