Create overrides (`DisplayVendorID-*/DisplayProductID-*.plist`) or use the existing ones\n2. Run `./install.sh`\n\n## Notes\n\n- Since macOS Mojave we no longer seem to need RGB edid overrides, they seem to be ineffective\n  - We can use `DisplayIsTV` =\u003e `false` instead\n- Tweak `target-default-ppmm` to enable selection of HiDPI modes in System Preferences -\u003e Display\n  - Also requires adding the appropriate HiDPI resolutions\n  - How do we calculate optimal ppmm for display x resolution?\n  - See [DELL U2715H](./DisplayVendorID-10ac/DisplayProductID-d066.plist) override for an example\n\n## Dumping display EDID\n\nCreate a dump for each display connected to your Mac.\n\n```bash\nn=0; \\\nioreg -lw0 | grep \"IODisplayEDID\" \\\n    | while read line; do \\\n        ((n++)); \\\n        name=display-${n}.edid; \\\n        sed \"/[^\u003c]*\u003c/s///\" \u003c\u003c\u003c\"$line\" | xxd -p -r \u003e$name; \\\n        echo \"Created $name\"; \\\n    done\n```\n\n## Resources\n\n- [Adding/Using HiDPI custom resolutions - tonymacx86.com](https://www.tonymacx86.com/threads/adding-using-hidpi-custom-resolutions.133254/)\n- [Display Override PropertyList File Parser and Generator with HiDPI support](https://comsysto.github.io/Display-Override-PropertyList-File-Parser-and-Generator-with-HiDPI-Support-For-Scaled-Resolutions/)\n- [edid-decode](https://git.linuxtv.org/edid-decode.git/)\n- [avibrazil/RDM](https://github.com/avibrazil/RDM) - Easily set Mac Retina display to higher unsupported resolutions\n- [usr-sse2/RDM](https://github.com/usr-sse2/RDM) - Fork, supports editing, icons, etc.\n- [xzhih/one-key-hidpi](https://github.com/xzhih/one-key-hidpi)\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fmafredri%2Fmacos-display-overrides","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fmafredri%2Fmacos-display-overrides","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fmafredri%2Fmacos-display-overrides/lists"}
