A recent update has fixed it! 18.04 as released comes with kernel
4.15.0-20-generic, which has the bad video effect. Latest update
(2/7/2018) includes 4.15.0-24-generic, which does not (it works
perfectly).
Thanks for your interest!
** Changed in: linux (Ubuntu)

Title:
Dell Inspiron 17r 5737 Ubuntu 18.04 Video Looks Very Strange
Status in linux package in Ubuntu:
Fix Released
Bug description:
When booting 18.04 on my Dell 5737 built-in screen the colours are incorrect
and the display looks to be of low resolution. This is true whether booting
from a fresh distribution copy on a memory stick or the subsequent patched
install. A screenshot:

The image on an external monitor is fine, and unplugging the external
monitor doesn't change anything.
WORKAROUND: Use kernel parameter:
nomodeset
