Problems
I HAVE DIGITAL
CABLE AND AFTER
SCANNING FOR
CHANNELS I GOT
NOTHING!
MY VIDEO IS BLACK
AND WHITE UNDER
YPBPR
I DON'T SEE AN
OPTION FOR THE
RESOLUTION 3840
x 2160 WHILE
CONNECTED TO
HDMI
This display does not support QAM. You'll need a cable
box in order for the display to work correctly. Make sure
you have a HDMI cable connected to the cable box and to
the display. Afterwards turn on the display and cable box
and make sure your display's source is HDMI.
Make sure you are not using yellow video cable connecting to
the YPbPr's green port. If you are you'll need to use AV as
your source instead of YPbPr.
Check and make sure your video card supports that resolution
and the cable you are using is HDMI 1.4 or higher. Make sure
the drivers are upgraded to the newest version possible.
