This might not be a problem at all if not using a UPS, but I haven't tested it.

I've no clear idea why, but suspect it might have something to do with stored charge in onboard capacitors having to dissipate before it will work again. But a few weeks or months set aside is all it needs to resume normal operation. I found it worked fine.Ī handful of thunderstorms later, I've come to the realization that *disconnecting power from the ASUS monitor* is all it takes to cause it to stop working. After a while, that monitor developed problems of its own, so I put it away and tried the ASUS again. I put it into storage and hauled out another (Acer) monitor to replace it. When I powered everything back up later, one of the monitors was dead. The problems began during a thunderstorm a few years back, during which I powered down the machine and then powered down the UPS serving it and the monitors.

I have two ASUS VS247 monitors, purchased years ago (new), which I initially used in a dual-monitor setup. If nothing else, I might be able to short-cut troubleshooting for others with the same problem. I realize this is a pretty old thread, but this is something I've encountered a number of times and in my case, the solution is pretty simple, albeit time-consuming.
