Fix DisplayPort-to-VGA Monitor

My second screen suddenly went dark and I need an expert eye to get it back. Here’s the situation: the PC outputs through DisplayPort, the monitor only accepts VGA, and the whole chain—cables plus DP-to-VGA adapter—worked flawlessly until yesterday. I have already unplugged and reseated every connector and brought all GPU and chipset drivers up to date, yet Windows still refuses to detect the display when I try to run it as an extended desktop. I’m not sure whether my adapter is active or passive, so part of the job will be confirming that and ruling it out—or swapping settings—to pinpoint the real fault. You’ll connect with me over a remote-desktop session or clear step-by-step chat, walk me through diagnostic checks in Device Manager, Windows Display Settings, and (if needed) the GPU control panel, and help me test any firmware or BIOS toggles that could be blocking the signal. The end goal is simple and measurable: the second monitor should reappear and stay stable, whether we leave it extended or verify it can mirror as well. Deliverable • A live, working VGA monitor driven from the DisplayPort port with the configuration saved so it survives a reboot. If additional parts are required, let me know exactly what and why; otherwise, your expertise should be enough to bring the screen back to life.
