My AN515-57-520Y drops performance when playing plugged into monitor

I have a gaming laptop which runs games smooth and fine, but since I bought a monitor it became most likely impossible to play anything, since after about 10 to 20 minutos the game and my entire system drops performance to like 13FPS (the GPU usage drops from 100% to 10% and CPU usage spikes from 10% to 90%) and the only fix is rebooting Windows, otherwise my system will run utterly slow. Sometimes the game only crashes, sometimes my entire system crashes, and even sometimes I get a Blue Screen of Death. Can anyone help me with that?

Already tried:

  1. Capping monitor to 144hz, and then to 60hz
  2. Turning off laptop's monitor to show only the external's
  3. Disconnecting HDMI dock

Laptop: Acer Nitro 5 Windows 11 Home i5-11400h RTX 3050 4GB VRAM 16GB RAM FHD 144hz

Monitor: TGT Altay TS4 FHD 180hz FreeSync
