<pre>Hi
On similaire computer Dell Latitude 5490,
CPU Intel(R) Core(TM) i5-8350U CPU @ 1.70GHz
00:02.0 VGA compatible controller: Intel Corporation UHD Graphics 620 (rev 07)
(prog-if 00 [VGA controller])
Kernel modules: i915
fedora 27 , kernel-4.15.10-300.fc27
when in bought it comes with BIOS version 1.0.8
the display works correctly (multi-screens, etc.). Wayland is working properly.
And I decide to upgrade BIOS to last Version 1.1.9
Release notes extract :

Intel Reboot issue.
-Updated Intel ME Firmware to address security advisories INTEL-SA-00086
(CVE-2017-5705, CVE-2017-5708, CVE-2017-5711 & CVE-2017-5712) &
INTEL-SA-00101(CVE-2017-13077, CVE-2017-13078 & CVE-2017-13080).
