--- Comment #13 from Coleman Kane (ckane@xxxxxxxxxxxxxxx) ---
Interestingly enough, the description of a problem attempting to be addressed
with this fix sounds similar to behavior I experience with this system:

Namely, the Radeon RX 580M connected over DisplayPort advertises 3840x2160@60Hz
but I've never gotten the card to successfully link up to the monitor at that
resolution. In console mode, this results in the "black screen" where only the
built-in display for the laptop works and the external monitor just stays black
(falls asleep). In Xorg, if I set it to 3840x2160@29.97Hz, it works however.
Additionally, setting the higher resolutions can take a noticeable moment to
display.

I have another laptop with another graphics card and was able to test that the
display does work at 3840x2160@60Hz.
