I have one monitor and a projector connecting to my computer, while the screen keep flashing after every 10 seconds, it seems the resolution keeps changing. The project is the a dual display for the monitor. They displays the same content. My current resolution is 1024*768, while after 10 seconds around, the resolution goes to something big, then after a few seconds, it goes back to 1024*768. I wonder if this is a problem about the resolution, or it's about the compatible of screen display?
