So here's a weird one: for the past few years, I've had a desk with room for only one monitor. I finally got rid of my printer and dragged my second monitor out of the closet, and now I can't get it to connect. I'm running Windows 10 and an AMD Radeon 6800 video card with updated drivers. The monitor is an Envision G218a1.
So far, I've tried:
- Attaching the monitor to the second DVI port on the video card while the primary monitor is plugged in.
- Clicking "detect monitor" in the Display control panel.
- Turning the computer off, unplugging the DVI cable from my primary monitor, plugging that cable into the second monitor, then turning the computer back on.
- Unplugging the second monitor, waiting for 30 seconds, and then plugging it back in.
- Pushing all of the buttons on the front of the monitor to get some kind of menu to come up. Only the power button seems to do anything.
- Cursing god.
Early on in this process, I did get a split-second flicker of my wallpaper on the second monitor during a reboot, but since then it's either a black screen or a constant cycle of solid-color screens that goes Grey-Red-Blue-Green-Black and then repeats endlessly.
The thing that really baffles me is that when I unplug the power cable but leave the DVI cable plugged in, my computer appears to recognize the damn thing. I can run my mouse cursor into the dead monitor and it takes a few seconds to run it back, I can drag windows over to the dead monitor and lose them, and my device manager shows that a monitor with the proper model number is connected. But every time I plug the power in, my computer immediately acts like I disconnected the second monitor. It vanishes from the device manager and the Display control panel, and my mouse won't go off the edge of the screen in the direction of the dual monitor any more.
Thoughts? I'd love a fix, but I'm willing to buy a new monitor if you guys think the problem is with the monitor and not my video card.
