I don't see many people using a perfect fit display for double-din. Why is that?
I have been looking into buying 8-8.1" 16:9 lcd/panel/display. The active area of such screen matches double-din size (180mm*100mm) almost perfectly.
Sadly none of the panels I looked at have capacitive touch screen, and those that do have a terrible 800*400 resolution.

One of the candidates is ZJ080NA-08A which is listed on panelbook with all the specs.
Second one is HSD080IFW1-A00 which is too listed on panelbook.

Is no-one insterested in having a screen that fills out 7"x4" double-din area?
