ddccontrol-db's Introduction

DDC/CI control database

Project ddccontrol-db contains database of monitor descriptors, which are used by ddccontrol and gddccontrol utilities to control monitor parameters using DDC/CI protocol.

Installation
- Installation from official packages
- Installation from sources
Usage
- From GUI using gddccontrol
- From command line using ddccontrol

Installation

The most convenient way to install ddccontrol-db is to use packages from official distribution repositories.

Manual installation is more complicated, but contains latest monitor profiles.

Installation from official packages

On Ubuntu based distrubtions ddccontrol-db, along with utilities, can be installed using apt:

sudo apt install ddccontrol ddccontrol-db gddccontrol

Instructions for other distributions will be prepared later.

Installation from sources

Install build depedencies (on Ubuntu):

sudo apt install intltool libtool m4 automake autopoint

Instructions for dependecies installation will be prepared later.

Latest repository can be cloned and built by:

git clone https://github.com/ddccontrol/ddccontrol-db.git
cd ddccontrol-db
./autogen.sh 
./configure --prefix=/usr/
make

Finally, the build can be installed using:

sudo make install

Usage

Monitor database is used indirectly with ddccontrol and gddccontrol utilities.

From GUI using gddccontrol

gddccontrol is a graphical utility for monitor configuration. It is called Monitor Settings in list of applications.

Currently, root privileges are required to control monitor parameters, therefore the launcher automatically asks for a password.

Utility can launched directly from commandline:

sudo gddccontrol

From command line using ddccontrol

ddccontrol allows monitor configuration directly from commandline. To probe I2C devices to find monitor buses use:

sudo ddccontrol -p

To read value of control 0x10 (brightness on VESA compliant monitors) for device dev:/dev/i2c-4:

sudo ddccontrol -r 0x10 dev:/dev/i2c-4

To set value of control 0x10 (brightness on VESA compliant monitors) to 75 for device dev:/dev/i2c-4:

sudo ddccontrol -r 0x10 -w 75 dev:/dev/i2c-4

See ddccontrol -h for more information.

LG 27UD58 (with reverse-engineered codes)

Hope this helps someone. These are some codes I reverse engineered for the LG 27UD58. I suspect they may match codes of other LG monitors as well. For some reason, I couldn't get i2c/DDC working through the HDMI ports so I only got VCP codes pertinent to the DisplayPort connection (the HDMI has some extra features like black level and deep color in the OSD). :(

LG 27UD58 (GSM5B09) VCP codes

0x15        PICTURE MODE (11=custom, 1=reader, 32=photo, 48=cinema, 9=dark room 1, 10=dark room2, 6=color weakness, 28=fps game 1, 29=fps game 2, 13=rts game, 14=custom (game))
0x87        SHARPNESS (0-100)
0xf5        RATIO (1=wide, 2=original)
0xf6        SMART ENERGY SAVING (0=off, 1=low, 2=high)
0xf7        RESPONSE TIME (0=off, 1=high, 2=middle, 3=low)
0xf8        FREESYNC (0=off, 2=basic, 3=extended)
0xf9        BLACK STABILIZER (0-100)
0xfe        GAMMA (1=gamma0, 2=gamma1, 3=gamma2, 4=off)

NOTE:
    - picture mode preset may not change all settings the same way as OSD does: sometimes have to change brightness/contrast, or other things, too
    - game modes may disable DSP to reduce input lag, so certain features like super resolution or DFC are not available in game modes
    - generic VCP codes like brightness, contrast, red, green, blue gain, audio volume seem to be working
    - haven't checked if input source works

Not detected in VCP codes...

????        SUPER RESOLUTION
????        DFC
????        COLOR TEMP
????        SIX-COLOR RedHue/RedSaturation/etc
????        POWER LED (not 0xfd as reported)
????        AUTOMATIC STANDBY

Other (don't recommend changing these... may malfunction)

Add support for Dell P2314H

Hi,

I have a Dell P2314H here. The version 0.4.2 of ddccontrol that is shipping with Fedora 23 as well as the DB with version 20061014 (release 7.20120904gite8cc385a.fc23). It does not seem to work with the monitor, even after doing modprobe i2c-dev and modprobe i915 as I think the latter is the Intel HD Graphics driver.

What can I do to support my monitor?

I cannot register in the Redmine. I registered with an email address but could not log in. Resetting the password tells me that the email is not known. Trying to register again tells me that the email address is already taken.

some controls may not work as expected.
Please update ddccontrol-db, or, if you are already using the latest

HP L2245wg

probably very similar to the HP LP2475w described in #31, but I figured i would keep that split out since the model numbers are different. i suspect it will end up being the same configuration because it's looking for the same file, namely /usr/share/ddccontrol-db/monitor/HWP26FB.xml, but i'll let you call the shots on that. :)

LG 29UM69G-B

Here follows the info I've collected:

Output of the "LANG= LC_ALL= ddccontrol -p -c -d" command considering the factory settings: https://gist.github.com/lucasPV/5f46c7ca89bc7acdb3294926a035e0de
The addresses and values that I've documented and tested until now: https://gist.github.com/lucasPV/e9736b949a67777947feb85dce444963
The XML file I'm temporary using for the gddccontrol: https://gist.github.com/lucasPV/460f523b735bdaad2db8e0a2c9e79543

I think that part of these settings are also valid for similar display models (like um67 and um68).

Hope this helps.
Thanks!

AOC I2276VW

Weird, it seems that it doesn't work at all, although DDC/CI is enabled in the monitor itself.
