"incorrect resolution" is because you have booted into recovery mode,
which disables proper resolutions via the "nomodeset" kernel parameter.
Please reboot and as soon as the purple screen appears tap "Esc". Now
select a normal kernel to boot that is not recovery mode.
If the problem still persists after that then please run:
dmesg > dmesg.txt
and send us the new 'dmesg.txt' file.
