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.
Change values by sliders or buttons, or use command lines, batch files,
create context menu popup entries, append arguments in icon properties shortcut target,
assign hot keys or mousewheel-combinations, which even works in fullscreen-games.
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

For controlling your monitor over monitorcable, a fully functional graphics driver has to be installed, (AMD, NVIDIA, INTEL should work)
and make sure your monitor has DDC/CI-protocol enabled, also your monitor must support MCCS (VESA Monitor Control Command Set),
but monitors differ in implementing MCCS, so not all arguments may work, besides some monitors offer predefined game and film-modes with fixed values,
which prevents some arguments from working.
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 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 some internal LCD-displays support less brightness-levels, the nearest level is chosen automatically.
If you don't prepend a monitornumber, monitorname, modelname 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 can create menu-popup-entries for executing command-lines, if you enter an additional comment,
you can show or hide the corresponding commandline.
ClickMonitorDDC offers in settings an option named 'show notifications'
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 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 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.
In special settings, you can define up to 8 times to auto-run-command-lines. Unchecking the corresponding checkbox deactivates the command-line.
If the time-condition is fulfilled then the command-line is executed one-time per day, not permanently like some other software-color-filter-programs do.
ClickMonitorDDC instead changes the real internal monitor-hardware-values. Monitor-values are stored in EEPROM inside monitor.
If EEPROMS are excessively written (at least more than 100000) they could lose storage-functionality, so more a theoretical issue.
But for safety ClickMonitorDDC does not continuously write to monitor.
Also executing auto-command-lines only one time allows you still changing values as you want.
07:00 AM b 30
08:00 AM b 40
09:00 AM b 50
07:30 PM b 40
08:20 PM b 30
08:40 PM b 20
If you boot up your computer at 02:00 PM then the nearest past time-command b 50 is executed one-time per day, at 7:30 PM b 40 will be executed one-time.
You can force executing command-line again by restarting ClickMonitorDDC, really exit and start again or use rescan monitors,
simply double-clicking ClickMonitorDDC will have no effect, because ClickMonitorDDC does not start again, if already running.
Alternatively entering and leaving ClickMonitorDDC-settings will also check and run auto-run-command-line.
You could also execute command-lines with multiple arguments
07:00 AM b 10 c 20 l 250
08:00 AM b 20 c 25 l 252
This would increase brightness, contrast and blue-luminance.
|If you are using multiple monitors,||b||+ or -||0 up to 100||sets brightness.|
|you can start command-line with||c||+ or -||0 up to 100||sets contrast.|
|selecting a special monitor,|
|the following arguments will be||p||6500K||select a color-temperature,|
|applied to this selected monitor.||possible temperatures are listed|
|If you do not select a monitor,||in ClickMonitorDDC-RGB-area,|
|the monitor under cursor||if you want to create your own color-temperature,|
|is auto-selected.||select User-color-temperature and modify temperature|
|You can select a Monitor by Monitorname,||by changing red/green/blue-luminance.|
|Modelname, Serialnumber or Monitornumber.||r||+ or -||0 up to 255||sets red-luminance.|
|Monitorname is listed in||g||+ or -||0 up to 255||sets green-luminance.|
|ClickMonitorDDC-window.||bl or l or i||+ or -||0 up to 255||sets blue-luminance.|
|If you pause the mouse pointer over|
|the listed monitor there will appear||s||HDMI1||select a monitor-input, usable input-names|
|a tooltip-window with Modelname,||are listed in ClickMonitorDDC-RGB-area.|
|Serialnumber and so on, but not all|
|Monitors deliver these informations.||v||+ or -||0 up to 100||sets volume|
|Monitornumber means position of the||m||mutes volume|
|listed monitor, but using monitornumber||u||unmutes volume|
|is not recommended, because sometimes|
|Windows changes positions.||x||shuts all monitors down to power-safe-mode|
|When specifying Monitorname, Modelname||q||terminates ClickMonitorDDC|
|or Serialnumber, omit spaces,||z||restarts ClickMonitorDDC|
|for instance HP w2207||?||notification about current brightness/contrast/volume|
|must be written as HPw2207|
|or use "HP w2207"||t||for instance t b 0 c 0 t b 90 c 80|
|toggles between b 0 c 0 and b 90 c 80|
|d||returns current Monitor-brightness,|
|e||returns current Monitor-contrast,|
|may be useful in batch files.|
|You can use multiple arguments in one commandline (maximum length 259 chars), for instance PL2779Q b + 10 c - 5 HPw2207 b 23 c 49|
This is the actual download version. ClickMonitorDDC supports multiple monitors, simply by clicking in the main-window, or by using commandlines
with monitorname/modelname/serialnumber/monitornumber, these commandlines can also be used for mousewheel + key-combinations,
but for easy use, you can simply use mousewheel alone over noctification-icons, but this way you cannot specify a concrete monitor,
now you can press key 1 up to key 9 while using mouse-wheel over icon to apply changes to this monitor.
ClickMonitorDDC realizes hotkeys by keyboard/mouse-hooks.
Now these hooks run in a separate thread, this way mouse/keyboard-handling should always be smooth.
Moving settings window around could sometimes cause some incorrect redrawing of settings window. Fixed.
ClickMonitorDDC shows all devices connected to graphics card, maybe you have a AV Receiver connected,
which shows up as a monitor, but cannot be controlled or there is an additional monitor connected, you never use.
You can right click an uncontrollable device (which is listed with brightness ? contrast ?),
then you can click 'Ignore this monitor for saving time', from now on ClickMonitorDDC-window should open a little bit faster.
Click 'Monitor gets checked again' if for instance you want to control a rarely used monitor.
Clicking 'Copy Debug-Infos of all monitors to Clipboard' can be used to email some debug-infos to the program-author.
These are only some special data, not a complete feature-listing of the monitors.
ClickMonitorDDC was primarily developed to control external monitors in the most user-friendly way, for instance use mouse-wheel over icons or define hot-keys and so on.
Internal Laptop-LCD have built-in brightness-support by using FN-keyboard-keys or windows-sliders, but ClickMonitorDDC can also speed up handling of internal Laptop-LCD.
This version comes with an unique feature for Laptop-Displays, activate this feature in settings by clicking 'same Laptop-Brightness for battery and plugged',
from now on Laptop-Display keeps same brightness ignoring power-source-changes.
Windows 10 comes with an additional Battery saver feature, which can automatically lower brightness, so for instance brightness 100 is forced down to brightness 70,
there is no way to set brightness back to 100 if Battery saver with lower brightness option is active,
therefore 'same Laptop-Brightness for battery and plugged' is temporarily deactivated if Battery saver is detected.
Battery saver also gets automatically activated if 'Power saver' plan is chosen and Laptop is on battery.
Monitor name should be defined in EDID using 0xFC descriptor, external monitors normally do this, but internal LCD-Display
often do not implement this 0xFC descriptor, instead sometimes there is a 0xFE descriptor, which means unspecified text,
ClickMonitorDDC now uses this unspecified text for monitor name if there is no concrete monitor name definition.
If a monitor is connected to graphics card, the monitor gets detected, that means EDID-information can be read by graphics-card,
the monitor can be switched off or even disconnected from power-supply, nevertheless EDID can be read,
because graphics-card delivers power to read monitor EEPROM.
Therefore a switched off or powered off monitor is listed in ClickMonitorDDC, but cannot be controlled.
Normally you should not plug or unplug devices during running your computer, but monitors are in most cases hot-pluggable,
therefore ClickMonitorDDC now detects at once if a monitor is hot-plugged, earlier versions also detected hot-plugged monitors, but maybe later.
ClickMonitorDDC shows values between 0 - 100, which is fine with external monitors, but internal LCD-display may support less levels, often only 16 levels,
for instance 1 3 4 5 6 8 10 13 17 22 29 38 49 63 80 100. Windows says every laptop must report a maximum brightness level of 100,
but there are old laptops reporting for instance 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15.
These numbers only reflect a corresponding hardware-brightness-level and different Laptop models often have different numbers.
ClickMonitorDDC now recalculates level numbers to 0 - 100 in a linear more user-friendly way.
Behavior of the 8 timers for auto-run commands was improved.
ClickMonitorDDC now uses for Laptop-Display-handling WmiMonitorBrightnessEvent, WmiMonitorBrightness, WmiSetBrightness, GetMonitorRawEEdidV1Block.
