Monitor fails to activate after powering down the machine.
You're experiencing a "no signal" issue after waking up from sleep or suspend. The keyboard and mouse work, audio returns, but the screen remains off. This is happening on your Windows 10 64-bit system with ASRock X470 Taichi graphics, running the High Performance Power Plan, and the screen is set to turn off after 15 minutes of inactivity.
