Screen flashed green while starting up pc

I had my screen flash green right after the starting windows animation finished. It was before logging into windows. Event log did not show up with anything unusual. Does anyone know what it is?

It could be a glitch in your monitor. One of my old monitors used to flash green or red sometimes but otherwise worked fine. Since I replaced that monitor it hasn't happened.

That might be what's happening to you? Is it happening on a consistent basis? Like each time you boot? Or only once in a while?

The occurrence has only happened once. I have seen it happen in a window for an internet explorer program a few times. The monitor is connected using a display port adapter.
