title: Advantech IDK-2121WR 21.5" Full-HD dual-LVDS panel

description: |
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).
