Re: S2721DGF, Ongoing Black Screen Issue

Today I contacted Dell Support for my S2721DGF going black after powersave, and would not show anything until I pull the power cord and reset the monitor.

The screen is black when this happens, it is no longer lit. The power button -is- lit.

The screen does not drop from Windows provisioning (e.g., my second and third screen does not start acting as the 'main' screen) until I press the power button. The sound of a device being disconnected also plays.

Things I have already tried:

• changing Auto Input to "no"
• Turning off G-Sync
• Turning off HDR
• Leaving the system and monitors alone and unpowered for 12 hours
• Re-seating DisplayPort plug on graphics card and monitor
• Trying different DisplayPort plugs on my graphics card
• Reinstalled Windows 11 Pro
• Installed new Graphics Card from an Gigabyte 4080 to an Asus Strix 4080
