For anyone else who's sick of the crappy 768p screen on the Vostro 3460, I found a way to upgrade to 900p screen.
The TL;DR version is that the LCD cable H58TK works with 900p screens.
I figured out that that a similar laptop, the Inspiron 7420, comes with a 1600x900 option and shares the same motherboard layout, so the cabling should be very compatible. I found the part number H58TK for the lcd cable, tried it with a 900p screen (B140RTN02.1) and it worked.
The next step is to replace...
