Only a single external monitor works with GPU, however my main laptop display and second monitor are blank?

Was trying to get the GPU setup and had some troubles with the versions of gcc, cuda and the nvidia drivers. Got it working after some trial and error, however only a single external display works. Leaving the main laptop and second monitor (connected via usc-c) displays blank.

Machine info:
Laptop: Asus PX13 HN7306WI-LX038XS
OS: Ubuntu 22.04
GPU: 4070 with 560 drivers

Any help is appreciated :)
