I have an RX580 nitro+ 8GB and I tried to attach a second "monitor" (really a projector) to watch videos while I use the main monitor to do internet surfing and other computery stuff. The problem is that both the monitor and the projector flicker when I do certain things, like moving the mouse arrow around or minimize/maximize windows, see this video for an example: AMD dual monitor flicker - YouTube The voice you can hear in the background is from a video playing on the secondary "monitor" (which also flickers when the primary monitor flickers).
What I'd like to know is if this is a hardware or a software issue (since my card is still under warranty).
P.S. My card is not overclocked (see the attached screenshot for the frequency details).
