Displayport-connected monitor not displaying anything

Currently, I have a desktop using an EVGA RTX 2080 GPU. My setup is one monitor connected to its only HDMI port, and a Dell S2417 using one of the card’s Displayport inputs. Over the last few days, I had noticed the Dell monitor would not work after waking up from sleep mode, but rebooting would bring it back. To that end, I bought a replacement cable hoping for an easy solution.

Today, however, the Dell monitor altogether has not displayed anything after boot. The best results I have gotten were when it would display the KDE login screen and a loading screen after a login, then it would stop displaying altogether.

Further, the Manjaro display settings menu recognizes both monitors, however I cannot enable the Dell monitor, shown below.

Steps I have taken:

  1. in my Windows partition, I disabled G-SYNC on the monitor (and updated drivers, which I understand is not directly related)
  2. reinstalled the “video-nvidia” display controller drivers within the Hardware configuration hardware panel.
