• If the source device not be able to convert the encoded Video toYCbCr
(4:2:2) as the receiver requests, the source device is not compliant with
HDMI fully. The problem is on the source device.
• Some TV monitor’s HDMI input accepts any kind of encoded video, if
connect this source device to TV directly, it seems no problem at all.
• Some brand Receivers accept more then one video formats through
HDMI input.
