Just got a, new to me, Dell optiplex 760 PC with windows 7 Pro

I want to use it with my Acer AL2016W lcd monitor which has an aspect
ratio of 1.6:1 (20" standard widescreen).

16:9 is standard widescreen.

Although true there are plenty of 16:10 ratio LCD monitors about.

The native resolution of my HP2475w is 1920x1200 means a small letterbox
when it is displaying 16:9

None of the resolution options match the ratio I need so when drawing
circles, they come out oval shaped.

How are you drawing the circles? If using Excel then circles are only
circular iff you select a fixed width font - otherwise they get kerned!

Didn't a driver CD(etc) come with the monitor? Or go to the maker's site
to look for one suitable for your current OS. But if an old monitor, may
no longer be supported.

There should be a driver for the monitor but selecting a display with
the same native graphics resolution as the monitor ought to work
(although you might have to tweak aspect ratio if the display has
non-square pixels). The devil is always in the details.

I do see some issue on programs that *assume* a 16:9 display.
