This script can simulate macOS HiDPI on a non-retina display, and have a "Native" Scaled in System Preferences.
Some device have wake-up issue, script's second option may help, it inject a patched EDID, but another problem may exists here.
Logo scaling up may not be resolved, cuz the higher resolution is faked.
