I think I killed my monitor.
Here's what happened:
First, my little brother was playing some game. Something happened (he doesn't know) and suddenly the amount we could see on our monitor was very little. What I mean is, the actual amount of screen that was being used by the monitor was very little. So I went into the monitor menu using the keys on the monitor (It's a viewsonic E771) and adjusted the horizontal to the right amount, and I maxed out the vertical but it still wouldn't reach. Somehow, through fooling around I fixed it, kind of. It's not perfect, but it is almost done.
However, in doing so I created a new problem.
Now, my monitor only displays 16 colours. I've done everything I can think of, going through control pannel ->display and all that, and my only options are 16 colours or 2 colours, where as it used to have 4 or 5 options. Also, my screen area is now stuck at 640 x 480, when it used to be 800 x 600. This I also can't change, and looking through microsofts website I couldn't figure anything out.
Anyone know what to do?
