Original title: 4K display HDMI and DisplayPort issues with RX 580
I just bought a 4K display (Philips 276E8VJSB) and it worked well on Windows 10 (version 1903). The display connected with an HDMI 2.0 cable will not have any signal immediately after booting into macOS 10.14.5, but the signal could be recovered by easily replugging the HDMI cable.
I also have tried a DisplayPort 1.4 cable today, and the problem mentioned earlier is solved. However, many of elements of the macOS user interface like the translucent sidebar would display only 4-bit colours (supposed to be 10-bit), resulting in colour banding, yet other things like images are not affected. Screenshots would not show the problem.
I used only MultiBeast to set my computer. Now I have to stay with HDMI as colours are more important than convenience for me. Although the issues are somehow minor, they are annoying to me. Sleep/Wake, however, always work well.
I would appreciate so much if one of them could be properly resolved.
Update: The DisplayPort colour banding issue is fixed via #19, and it may happen on different scenarios as well. The HDMI issue is on hold as it is currently not possible to determine where the problem is.
