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.
