Troubleshooting
of an image or poor quality images are often caused by the wrong connection.
Turn off the display and check each pin of the cable separately. If you think
you have a defective cable, we are happy to exchange it for you - you do not
have to send the display back.
Avoid short circuits! Please be careful before connecting power to the display
l
that there are no cables that have not yet been connected at both ends. If the
monitor does not power up, try another outlet or another power source.
Provide the display with a 12V DC power supply only. Higher or lower voltage
l
can permanently damage the display and is not covered under warranty. Also
make sure you supply only one power source.
Startup:
Please note: After you switch the display on, you may have to change the input
mode (VGA/AV1/AV2) 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.
1. Display remains black
Connection error: Please check again to make sure that all cables are
l
properly connected.
Resolution / activation errors: Using the right resolution and activating the
l
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.
It is often best to use the display at a resolution of 800x480,
Tip:
800x600 or 1024x768 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
l
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.
2. Stripes / errors in the image
Pixel error: Each faytech display has been thoroughly tested and sold with no
l
pixel defects. If there is a pixel error at your display, please contact us for
Support.
Text is hard to read, picture looks fuzzy: If the display screen is focused and
l
text looks good at resolutions of 800x480 and 800x600 at 60Hz, then the
problem is probably due to the interpolation the display performs at higher
resolutions. This can lead to inaccuracies in the representation and pixel
vibrations. Best performance will come at resolutions of 800x480, 800x600
or 1024x768 at 60Hz.
Stripes / errors in the image: When connecting the display using power from a
l
PC's power supply, the power supply can cause a light flickering. This is
because of the interference created by the PC's power supply. In order to
improve the picture, please try an alternative power supply.
