Make sure the 12V power is plugged in the back of the unit.
Check to see if the power LED light is on.
1. In case your video source is HDCP enabled, make sure your
video display (HDTV) is HDCP compliant.
2. If you are using a copper based HDMI cable, overall length of
the cables (length of the cable from video source to switch and
length of the cable from switch to display) should not exceed
20ft. Exceeding 20ft. with copper based cables will result in no or
poor picture quality. To extend beyond 20ft, please use fiber
optic HDMI extension cables such as the Purelink HDX II series
3. Use high quality HDMI cables.
4. If you are using computers, try other refresh rate settings.
Most HDTV's have refresh rate of 48Hz and computer's video
cards are usually set at higher refresh rate. Try lower refresh
rates.
5. Make sure all HDMI connectors are tightly secured to all
HDMI ports. Loosened screws on the HDMI connectors will
result in no or poor picture.
6. Turn off all equipment (video source, switch and HDTV) and
restart all equipment.
Please remember that your video source will only transmit one
resolution setting. To connect varying resolution displays
(1920x1200 resolution display and 1024 x 768 resolution
display) the resolution setting of your video source must be set
to the lowest resolution setting (1024 x 768).
