Monitor not detected, only non-PNP monitor used

I have been using Windows 7 and an external monitor, an Acer AL2216W, for several weeks.  The monitor res of 1680x1050 was being used.  I rebooted and now 1680x1050 is no longer a choice.  When I use the Screen Resolution widget, it lists the monitor as Generic non-PnP Monitor.  I get a choices for various resolutions only some of which the monitor will display.  I elected to use 1600x1200 but the fonts are blurred and at 1680x1050 the characters are crisp.  I have tried to install the monitor driver for the Acer AL2216W monitor, but windows tells me that it likes its current driver more and won't install it.  Do you know what I could try to have this monitor properly detected?

Thanks!

This is resolved.  The monitor had to be unplugged, powered down, and then replugged.  Having done that the monitor is again detected by all the computers.

Thanks
