I just completed a clean install on a new build. Acer monitor's native display is 1920x1080 but does not appear as an option in LM "Display". The only choice is 1024x768 (4:3). The default display detected is "Laptop". The desktop notice appears regarding LM "running in software rendering mode" suggesting a problem with drivers.
I cannot find any resolution (pun intended) to this problem so any help is much appreciated.
