 Provide the display with a 12-36V DC power supply only. Higher or lower voltage can
permanently damage the display and is not covered under warranty. Also take care that
you do not mix polarity.
STARTUP:
Please note: After you switch the display on, you may have to change the input mode
(HDMI/AV/SV/VGA) in order to receive a signal. If there is no signal source connected, the
display will show "no signal" and go off automatically after a short period of time.
Display remains black
 Connection error:
Please check again to make sure that all cables are properly connected.
 Resolution / activation errors:
Using the right resolution and activating the display is a common problem that is often not the
fault of the display itself. The monitor supports the resolutions given in the technical data.
Sometimes during simultaneous operation of two displays on a PC or the connection of an
additional display to a notebook complications can arise. Usually these problems need to be
resolved in the hardware and software of the PC. It is always best to use the display initially as
a single display with a resolution of 800x600 at 60Hz. Try to start with this resolution then
experiment with other resolutions and other combinations of displays to see which work best
for you.
Please note that extended desktops often are black in the beginning. In this situation your
display may be black at first if you configure it as an extended desktop.
Tip: It is often best to use the display at the following resolutions: 7” 800x480 or 800x600,
8” 800x600, 10” 1024x768, all at 60Hz. If the display is used as a second display with a
PC, which is already connected to a display with a much higher resolution, configure
resolution profiles. With an ATI graphic card, you can set up profiles in the advanced
catalyst control center under profiles. Activate a hotkey, so that you can change the
profiles of each display (one is the touch display, the other is the higher resolution display).
Also you can configure the profiles using a software tool such as powerstrip.
 Power supply error:
If the display has no signal input, there might be an error with the power supply. First please
check the connection with another power supply before you return the display. We're happy to
exchange the defective power supply if necessary.
