Unexpected screen flicker only when using my new USB-C monitor on my work laptop

I recently got a USB-C monitor to use with my work laptop (Dell XPS 13, Windows 11) because I wanted a cleaner desk setup without extra cables. The monitor works fine most of the time, but I’ve noticed a weird flickering issue that only happens when I’m connected through USB-C. If I use HDMI instead, the flicker disappears completely. I’ve tried updating the laptop’s graphics drivers and the monitor’s firmware, but nothing seems to fix it. The flicker is subtle but annoying during text-heavy work, and it gets worse if I move the laptop or the cable at all. I also swapped the USB-C cable with the one that came with the monitor and a third-party one, but the flicker persists. I’m hoping to avoid switching back to HDMI because the USB-C connection charges my laptop and supports touch controls on the monitor, which I want to keep using. Has anyone else run into USB-C flickering issues with external monitors? What troubleshooting steps helped you narrow down or fix this kind of problem?
