M2 Mac Mini Pro Display Issues

I'm wondering if anyone is having similar issues to me. I bought a m2 mac mini pro, base model 16gb/512gb. Got it last week and was working great with my 2 4k 144hz Dell G3223q monitors. Ran at full resolution with max refresh rate on both. Left monitor was connected via Displayport to USB-c cable, and right was connected via HDMI to HDMI cable.

I wanted to see if the mini was capable of running both monitor using displayport to usb instead of the right using HDMI, so I ordered the same cable again on amazon and hooked the right monitor up the same way as the left monitor. 

To my finding it could support 4k @ 144hz via displayport to usb-c on both monitors. Then about 2 days later, some weird stuff started happening on the monitors. 

Every time I would come back in the morning to use the monitors, the display settings would be all wack. I would wake my mac using the keyboard or track pad, and both monitors would be mirroring on the lowest possible resolution (1080p) @30 or 60 hz. Then when I would go to display settings, the max refresh rate I could select would now be 60hz, and to my findings the only way I could get 144hz as an option again would be to power off the monitor and turn it back on, only then would 144hz show up under refresh rate again. 

Really weird, it was working wonderfully the first two days, no issues at all. Didn't mirror the main display after coming back the next morning, always had the right resolution on the lock screen. I literally can't think of anything that changed except for me trying to use (2) displayport to usb-c cables. I even tried using HDMI again to see if maybe using both via displayport wouldn't work, and it's still giving me these issues. I dont know what else to change/try/do.

Any ideas?
