I’ve two exterior screens linked to my MBP 16″ and after I take the MBP out of sleep mode one of many two screens by no means connects again up. One monitor is linked with USB-C to USB-C and all the time connects when the MBP comes out of sleep mode. The second monitor is linked with USB-C to DP cable and this one stays black till I disconnect the cable for 2 minutes then plug it again in (< 2 minutes and the OS would not appear to see the monitor was disconnected and will not reset issues.) After I have a look at the shows within the system settings it is solely exhibiting the built-in and the one linked on USB-C. Every monitor is linked on to the MBP unfold between the 2 separate bus connections for the USB-C/Thunderbolt.
I’ve additionally tried utilizing a OWC twin DP adapter which solely made issues even worse as I needed to restart the MBP every time I reconnected the screens and solely may get certainly one of them to work at a time regardless.
I am working 10.15.four OSx and I’ve the AMD Radeon Professional 5500M four GB graphics card.
I am actually new to the Mac world and I am struggling to discover a working resolution to the problem apart from what others have posted for solutions which is disconnect the cable and reconnect it. One further reply that somebody posted was upgrading the drivers however that was for the docking station they have been utilizing.
Why would just one monitor restore after being resumed from sleep?
