ClickMonitorDDC 3.5


Click taskbar notification icons to adjust the real monitor-backlight-brightness/contrast
or use mouse-wheel over notification icon to increase/decrease corresponding value,
much more comfortable and faster than manually messing around with monitor buttons,
works with external monitors (DDC-protocol) and laptop-LCD-Display.
The notification icons inform you about the monitor values,
you simply look at the icons to check if the wanted values are already set.
Changing values can be done by sliders or buttons, but you can also use command lines,
assign hot keys, create context menu popup entries, use batch files
or append arguments in icon properties shortcut target.

You can use multiple arguments, for instance  b 20 c 30
sets monitor brightness 20 and contrast 30.
b + 6  c - 8 increases actual brightness by 6 and decreases contrast by 8
optionally you can prepend monitornumber or monitorname or serialnumber
2  b + 10 increases brightness of second monitor by 10
PL2779Q   b 36 sets brightness 36 for monitor with name PL2779Q
use for monitorname or serialnumber at least two chars.
select monitor-color-profile, for instance   p  6500K
change user-profile-colors, r for red, g for green, bl or l for blue, range 0-255
select monitor-input  s HDMI1  s DisplayPort1  s DVI1 (or HDMI2  DisplayPort2   DVI2)
v 90 sets volume to 90%, v + 10 increases volume by 10%, v-8 decreases by 8%
m for mute volume, u for unmute, x for shutting off monitors, q quits program.
t  b 0 c 0   t  b 90 c80 toggles between b 0 c 0 and b 90 c 80

The portable file can be run from any location without installation, needs windows 7/8/10

more Information

ClickMonitorDDC can adjust brightness and contrast of external monitors
by using DDC-protocol over monitor-cable (DVI, HDMI, DisplayPort, VGA).
Nearly all monitors support DDC-protocol, but some monitors may not work
because of faulty or no DDC-protocol. A few monitors allow to deactivate DDC-protocol,
this is not recommended, also windows makes use of DDC to find out about best resolution.
Some monitors offer special modes with fixed brightness/contrast for games etc.
In this case adjusting values will fail.

ClickMonitorDDC is managed by its notification icons, therfore make sure that
these icons are not hidden, but shown on the taskbar notification area.
windows 7: right click taskbar, click properties, click customize notification area,
windows 10: right click taskbar, Settings, Select which icons appear on the taskbar.
If you want to change the sequence of taskbar icons, simply drag and drop the icon.

ClickMonitorDDC can create menu-popup-entries for executing command-lines,
if you enter an additional comment, you can show or hide the corresponding commandline.

If you don't specify a monitornumber, monitorname or serialnumber in command-lines,
then the commands affect the default monitor, which is the selected monitor
in ClickMonitorDDC-window, you can select another monitor as default.
If you run multiple monitors, then ClickMonitorDDC automatically sets the monitor
under the cursor as default monitor, you can disable this feature in settings.

ClickMonitorDDC offers in settings an option named 'Hot key notification'
If you set values directly in ClickMonitorDDC-window, this option has no effect,
but if you press defined hot keys and ClickMonitorDDC-window is invisible,
then setting this option gives you an optical feedback, what the pressed hot key did.

ClickMonitorDDC also offers volume control, but this is not done by DDC-protocol.
Adjusting volume can be very complex, because of different devices and formats,
stereo, compressed, uncompressed multi-channel and so on.
Best thing is simply to use the windows-functions. Windows offers sliders to do this,
nevertheless I added this feature because you can define hotkeys for adjusting volume.

ClickMonitorDDC supports easy to use command-line-arguments,
maybe the rarely used toggle-feature needs some extra explaination.
for instance define a hotkey with this commandline
t  b 0 c 0   t  b 100 c 100
first time you press the hotkey, you set first monitor brightness 0 and contrast 0,
second time you press the same hotkey, you will set brightness 100, contrast 100,
third time behaves like first time and so on.
this way using one hotkey, you can execute two different profiles in turn.

Monitors have many inputs, you can select monitor-input by for instance s HDMI1
usable input-names are listed at the bottom in ClickMonitorDDC-RGB-area,
but some monitors do not correctly support selecting inputs,
you can try to select an input by number, for instance s 17 should select first HDMI-Port,
but I do not recommend doing this, I disclaim any responsibility for any harm.
MCCS-Standard defines monitor-inputs by numbers:
1 VGA1
2 VGA2
3 DVI1
4 DVI2
15 DisplayPort1
16 DisplayPort2
17 HDMI1
18 HDMI2

ClickMonitorDDC also allows setting brightness of laptop/notebook-LCD-Displays.
Laptops have special FN-key-combinations to do this, nevertheless I implemented support
for laptop-brightness, because laptops allow to add an external monitor,
and it would be irritating if ClickMonitorDDC would not show both displays.
ClickMonitorDDC shows values between 0 - 100, which is fine with external monitors,
but the internal LCD-display supports normally only a few levels,
for instance 16 levels, for instance 1 3 4 5 6 8 10 13 17 22 29 38 49 63 80 100,
so setting brightness 70 would result in setting brightness 63
Windows hides this irritating numbers from user, and offers only a few positions.
