--- Comment #2 from Leho Kraav (:macmaN :lkraav) <leho at kraav.com> ---
I'm not sure if this U4919DW monitor is true 5K?

> 5K resolution refers to display formats with a horizontal resolution of around 5,000 pixels. The most common 5K resolution is 5120 × 2880

Our target resolution here is 5120 x 1440.

Also, bug 97244 talks about dual inputs etc, while my U4919DW monitor ran fine
over a single USB-C cable on Dell 7480 KBL graphics.

But looks like people are testing drm tips as a general debugging process, so
I'll give that a shot first.
