EDID Editor inspects and edits EDID, the data a display sends to describe itself: its name, size, timings, refresh ranges, color and HDR support, and audio formats. It is written in C++ with GTK 4 and libadwaita, and is based on wxEDID by Tomasz Pawlak.
It reads the EDID base block, CTA-861 extensions and DisplayID 1.x and 2.x blocks, from
binary files, from hexadecimal text as printed by edid-decode or xrandr --verbose, or
from a connected display through /sys/class/drm. The display itself is never written
to. An overview sums up the whole EDID, every field can be edited with its value named
and its bytes marked, detailed timings have a visual editor, data blocks can be added,
duplicated, moved and deleted, and two EDIDs can be compared field by field. Saving
recomputes the checksums and keeps data the editor does not understand.
edid-editor-cli does the same from a terminal, without a display: it lists and reads
every field, sets fields, adds, duplicates, moves and deletes groups, and compares and
converts EDIDs. It prints JSON for scripts, and comes with a manual page and completions
for bash, zsh and fish that read groups and fields from the file being edited.
An edited EDID loaded with drm.edid_firmware or a compositor override can leave a
display blank or out of range. Keep a way back, such as a second output or a boot entry
without the override. EDID Editor comes with no warranty, see LICENSE.
Fedora 44, 45 and Rawhide, from the Copr project sachesi/software:
sudo dnf copr enable sachesi/software
sudo dnf install edid-editor
openSUSE Tumbleweed and Slowroll, from the OBS project
home:sachesi:software; for
Slowroll the address has openSUSE_Slowroll in it, and on aarch64 openSUSE_Factory_ARM:
sudo zypper addrepo https://download.opensuse.org/repositories/home:sachesi:software/openSUSE_Tumbleweed/home:sachesi:software.repo
sudo zypper install edid-editor
Debian testing and Ubuntu 26.04, from the same OBS project; for Ubuntu the addresses
have xUbuntu_26.04 in place of Debian_Testing:
sudo install -d /etc/apt/keyrings
curl -fsSL https://download.opensuse.org/repositories/home:sachesi:software/Debian_Testing/Release.key | sudo gpg --dearmor -o /etc/apt/keyrings/sachesi-software.gpg
echo 'deb [signed-by=/etc/apt/keyrings/sachesi-software.gpg] https://download.opensuse.org/repositories/home:sachesi:software/Debian_Testing/ /' | sudo tee /etc/apt/sources.list.d/sachesi-software.list
sudo apt update
sudo apt install edid-editor
Debian 13 and Ubuntu 24.04 ship a libadwaita older than EDID Editor needs.
Arch Linux: the AUR package edid-editor, built from
packaging/aur/PKGBUILD, which each release tag updates.
The same packages are attached to each release.
just build
sudo just install # or: just prefix=$HOME/.local install
just gui=disabled build # only edid-editor-cli, without GTK
just uninstall # with sudo if it was installed with sudo
just run [FILE] # a debug build, uninstalled
builddir/cli/edid-editor-cli --help
just runs Meson; meson setup, meson compile and meson install work as well.
Building needs Meson and a C++17 compiler, and for the application gettext and the
development packages for GTK 4.22 and libadwaita 1.9 or newer. Without them, or with
gui=disabled (-Dgui=disabled for Meson), only edid-editor-cli is built. The tests
of the interface also need Weston, Xwayland, xdotool, the session bus and the Python
bindings for AT-SPI, and are skipped when those are missing.
