While messing around in ADB, I found where the screen resolution values are stored (allegedly) persistently:
  • Connect to vehicle via ADB (default port 5555 for wireless)
  • Enter `adb shell`
  • `su`
  • `cd /data/property`
  • `busybox vi persist.sys.NV_DISPXRES`
  • input `i`, then delete default value `800` and replace with `1600`
  • input `ESC`, then `:x`, `ENTER`
  • `busybox vi persist.sys.NV_DISPYRES`
  • input `i`, then delete default value `480` and replace with `960`
  • input `ESC`, then `:x', 'ENTER'
  • `input keyevent 26` (screen should turn off)
  • `input keyevent 26` (screen should turn back on)
  • If above doesn't refresh, exit the shell terminal and try `adb reboot` (or just reboot the unit manually)

That's a worthy endeavor indeed, thanks! Can you post a picture of the result?
