have a LC-M27-4K-UHD-144 monitor and use it with one displayport cable and get 4k 120Hz.
But as soon as I connect another external FHD 60Hz monitor (or my Hifi receiver), the refresh rate jumps to 60Hz and I can no longer select 120Hz.
Monitor vendor suggests that maybe the RX560 is not "strong enough", although it should be capable for 4x 4k 60Hz monitors.
Anyone who can confirm that the RX560 can handle 4k 120Hz plus an additional monitor?
Don't need eyefinity, desktop is in clone mode since the 2nd external monitor is my Hifi receiver and doesn't need to display a picture at all.
