Windows does not show the desired display
settings
Should you have problems selecting display settings for portrait
oriented displays in the Windows Display Properties control panel,
disable the option
Hide modes that this monitor cannot display
in
the control panel (see below).
Information:
The display contains a special memory chip that contains information
about the display's scanning capabilities. When Windows starts up, it
reads the contents from this memory and presents a number of
display settings in the Display Properties control panel, based on this
information.
The memory of this display contains the information the display can
handle scanning systems up to 120 Hz. That is why Windows will
propose a display setting with a high refresh rate.
However, it is best
to select a refresh rate of 60 Hz.
The information that the display can be used in portrait mode, is also
stored in the display memory. However, Windows does not recognize
this and presents only default landscape modes if the option
Hide
modes that this monitor cannot display
in the control panel is
enabled.
Pixel Faults
Permanently dark or bright pixels can happen to TFT displays. 10 or
less permanently dead pixels do not make out a good case for
exchanging the unit.
Please contact our Customer Service Department if the number of
pixel faults exceeds the above-mentioned figure.
