Look like I wrapped the wrong text, maybe this copy came from vendor code. Yes, the datasheet mentioned this as WXGA resolution. Thanks for this.

Though JD9365DA-H3 itself is not a direct panel, we usually denote controller IC as panel driver as these are part of Linux DRM panel and as its own compatible "jadard,jd9365da-h3" Thanks, Jagan.
