I have two displays connected to the desktop. The Dell monitor is connected by HDMI and the TV is connected with a DP to HDMI adapter. The TV is seen as the primary display. After waking from sleep, sometimes the Dell monitor doesn't connect and displays no signal. If I turn on the TV it displays correctly. Unplugging the HDMI/DP does not detect the monitor and a restart is required. More recently, when I turn on the tv (second display), Chrom will display black. I can open other windows fine but need to restart Chrome. Does anyone have any idea what is causing these problems? I didn't have these issues with my last monitor.
