Hi,
basically what happens is that, sometimes, when I let the pc being in standby for some time or when I just turned it on, the monitor starts to do this thing (shown in the attached video). The bug, as also shown in the video, fixes itself once I turn off >> turn on the monitor, as of right not, with 100% success rate.
I just bought this RX580, it's still under the Amazon's warranty so I would like to know if I should replace it or keep it, hoping for the best.
