[macguru9999]

Is anyone using the
LG 27UL600-W UHD FreeSync IPS HDR 27in Monitor with a cMP 5,1 and Sapphire rx580 ? How does it go ? I would think just fine but thought I would ask before purchasing .....

Nice monitor. I've been using an LG 4K monitor (27UD88-W) with a Pulse RX 580 graphics card without issues... until recently. Since macOS 10.14.4, I've had to power cycle the monitor to get it to display an image after wake from sleep. This happens when using the DisplayPort; HDMI is fine. Booting into previous macOS versions confirms that the problem is software.
