|
The IDK-2121WR from Advantech is a Full-HD dual-LVDS panel.
|
|
A dual-LVDS interface is a dual-link connection with even pixels traveling
|
|
on one link, and with odd pixels traveling on the other link.
|
|
|
|
The panel expects odd pixels on the first port, and even pixels on the
|
|
second port, therefore the ports must be marked accordingly (with either
|
|
dual-lvds-odd-pixels or dual-lvds-even-pixels).
