I just bought and installed an RX 580 and I appear to be having an issue. I have 2 monitors, exactly the same and both connected through DisplayPort. Sometimes I will come the computer and only turn on 1 monitor when I just need to look at something real quick. If I find myself staying on longer, I will they turn on my second monitor. In most cases though, whenever I turn on my second monitor, both monitors will start blinking then they will both go black and lose signal completely. I would then try to connect an HDMI to the integrated video on the motherboard but I would still get nothing. This has happened a few times and has required a computer restart to fix.
At one point, the monitors was not receiving a signal at all even after I turned them on both at the same time.
What could be the issue?
I have updated the drivers to the most current.
I do leave my computer on for extended periods as well.
Exact video card is: XFX RX-580P8DFWR
