I have only use same size screen, the mother board is output LVDS, the screen also use LVDS signal, so only did a cable, and test, lucky the mother
board could support 1400x1050 resolution
about the keyboard, I have used a SK-8845 main board for it, the hard work is found define for each pin on keyboard. But forget it, I have found another easy way for keyboard , if you could find MONKEY controller, it’s very easy, it’s works on my another project 230CS (it’s delay about 1 year, because my work), and you could define WIN key also.
Finally, the track point ,I have use TP mainboard connected the sense on keyboard. I think you will know how to connect to mother board.
Hope it’s could help you
