My main monitor works fine, it is a 240hz monitor by OMEN (i use displayport) . I have a 75hz acer monitor as my second monitor(hdmi). As soon as i plug in my second monitor with the hdmi cable in my graphics card (rx580) it just duplicates/mirrors the displays and it says the only monitor detected is my acer one even though my omen monitor is on and working. My system also keeps randomly crashing. Please help this is a fairly new build. I already tried all the driver fixes, like reverting to an old one or installing the most recent one.
