I have a 3rd gen Intel laptop with only Ubuntu 19.10 installed, and a monitor attached via DisplayPort. The monitor has a native resolution of 2560x1080. When I power on my laptop, it is seemingly random whether one of the three following situations occurs.
1. Displays at the proper native resolution of 2560x1080,
2. Displays at 1600x1200 but not let me select a higher resolution in display settings, or
3. The display will fail to connect and stay blank (when I enter display settings it will be on "Single Monitor" mode, but from there I can enable Join Displays and set it to its native resolution).
Please note I selected "I don't know" instead of gdm3 or lightdm since i've been having this issue since before installing/switching to lightdm.
Please let me know what additional information I can provide at this time.
