| |
Hardware: Dell Latitude 7400 2-in-1, Whiskey Lake, Intel 620
5120x1440 fails to display.
Next available mode 3840x1080 displays fine.
Is this a kernel, or a driver level issue? It fails both in Xorg and Wayland, so seems something at the lower levels. This 49" monitor worked fine on Latitude 7480 (Kaby Lake), so I'm thinking something with `i915` module layer.
What should I try next?
