# Display Overrides for macOS (Big Sur)
This repository is for display overrides to make (my) monitors work better on macOS.
For Catalina and older, see [catalina](../../tree/catalina)-branch.
## Goals
- Force HiDPI modes for screens that are not supported (by macOS)
- Force picture modes on misbehaving screens
- Fix displays detected as TVs
- Make sure Night Shift works on external displays
- Allow picking HiDPI modes in Display preferences like for retina displays (less realiant on RDM)
- Custom icons for displays
## Usage
1. Create overrides (`DisplayVendorID-*/DisplayProductID-*.plist`) or use the existing ones
2. Run `./install.sh`
## Notes
- Since macOS Mojave we no longer seem to need RGB edid overrides, they seem to be ineffective
- We can use `DisplayIsTV` => `false` instead
- Tweak `target-default-ppmm` to enable selection of HiDPI modes in System Preferences -> Display
- Also requires adding the appropriate HiDPI resolutions
- How do we calculate optimal ppmm for display x resolution?
- See [DELL U2715H](./DisplayVendorID-10ac/DisplayProductID-d066.plist) override for an example
## Dumping display EDID
Create a dump for each display connected to your Mac.
```bash
n=0; \
ioreg -lw0 | grep "IODisplayEDID" \
| while read line; do \
((n++)); \
name=display-${n}.edid; \
sed "/[^<]*$name; \
echo "Created $name"; \
done
```
