Monitors not working. Help? - sh.itjust.works

Hi everyone. I’m just getting into Linux and went with Kubuntu as my first real distro. its worked pretty good out of the box and I haven’t messed with it much but I’m having problems with my monitors. I have a three monitor set up using my laptop and two external monitors, they are a set of paired docking monitors from Targus connected by usb-c. it worked fine at first but then every few days they started turning off and I had to hit the button on the monitor to turn them back on and now its at the point where turning them on only connects for a couple seconds before they both say no input detected and turn off. but I’ve also discovered that one monitor will still work fine if i disconnect the power from the second monitor. I’ve tried updating to the latest nvidia driver as well as going back to a previous version but honestly i don’t know if I’m even looking in the right place. Does anyone have any advice? I’m using a Dell G16 7630 with RTX 4060.
