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.
Fix Mojave flower screen thanks to the resolution parameters provided by @Steeeve
System Preferences
Run script in Terminal
$ sh -c "$(curl -fsSL https://raw.githubusercontent.com/xzhih/one-key-hidpi/master/hidpi.sh)"
If you cant boot into system, or get any another issues, you can use clover -x reboot or into Recovery mode, remove your display's DisplayVendorID folder under /System/Library/Displays/Contents/Resources/Overrides , and move backup files
In Terminal:
$ cd /Volumes/"Your System Disk Part"/System/Library/Displays/Contents/Resources/Overrides
$ VendorID=$(ioreg -l | grep "DisplayVendorID" | awk '{print $8}')
$ Vid=$(echo "obase=16;$VendorID" | bc | tr 'A-Z' 'a-z')
$ rm -rf ./DisplayVendorID-$Vid
$ cp -r ./backup/* ./
