For those wondering if you can upgrade your pi-topCEED's display, the answer is YES! I wanted to install a higher resolution display, so I took a gamble and went over to eBay purchased a 14" FHD EDP LED LCD Screen 30 Pin for HP Chromebook 14 G4 and it works beautifully. It's a 1920x1080 TN panel.
It does have (as far as I know) one caveat, the CEED's case is pressing against the upper 2 corners of the screen resulting in somewhat noticeable dark grey blobs at the corners where there's pressure against the LCD. So depending on the display you source yours from, your mileage may vary. Good news is It's hardly noticeable if the whole screen isn't black.
