Image quality problem L’image du fond d’écran n’est
pas de bonne qualité. The transmission quality
deteriorates rapidly above 5
meters in length depending on
the quality of the HDMI cable.
HDMI signal quality is detected
when shadows appear.
HDMI amplifier adapters must be
installed.
For 10 meters lengths, XO offers
a PA-120 cable set (USB - HDMI
- Serial).
The screen background is of
good quality, but the image
transmitted from the Dürr HD
camera is greenish. If the background is correct no
distortion or shadows, but the
image transmitted by the Dürr HD
Camera has greenish, pinkish or
yellowish reflections indicates in
90% of the cases that
transmission problems are
affecting the image quality.
It is recommended to add a USB
amplifier adapter between the
camera's USB connector in the
terminal and the PC's USB cable.
