I have two issues with the following triple monitor setup and my RX 560 card under Win 10/64:
LG 27UD58B 4k Monitor connected DP - DP
Samsung 28UE590D 4 Monitor connected HDMI - HDMI
Panasonic TX-L40EX34 FHD TV connected with DVI -> HDMI cable
Probably since the last few driver updates under some conditions (e. g. rebooting, sometimes after sleep) the system hangs with black screen. A
fter unplugging the TV and rebooting, Windows starts up normally. When windows has booted, I am able to plug in the TV and all three screens work fine.
As I have exchanged one Monitor (from an LG 22" FHD to 27" 4k), it might only be an issue with both 4k screens. With 4K/FHD/FHD TV it worked fine.
Second issue is HDMI Sync on my Samsung 28UE590D: The Monitor regularly loses sync (1 second black screen), when connected to its HDMI 2 port (HDMI 2.0), connected to its HDMI 1 port (HDMI 1.4) it works fine, but only with 30 Hz refresh rate. I currently have changed the LG's and Samsung's connections (LG HDMI, Samsung DP).
Until now, no sync issue @ 59.9 Hz.
Is there a perspective to get fixes for these issues?
