Improving the Viewsonic monitor’s resolution

Upon reinstallation, I found my monitor's resolution (viewsonic va2038wm) was not as good as it should have been, even after installing all relevant drivers. (on Windows XP)

The problem was that I had gone to the My Computer > right click Properties > Advanced > Performance > Settings > Visual effecs > Adjust for best performance.

That's because the computer was misbehaving itself (a separate problem). 

By reverting back to the default (Let Windows choose what's best for my computer), the resolution has reverted to the very fine and hiqh quality one that I had seen in the previous installation of Windows XP.

All fixed.
