i had that problem too with cs but fixed now.
you can fix that in nvidia control panel > adjust desktop size > use nvidia scaling.
it is related to screen scaling.
hope that helps.
Might it be flatron w1941s rather than FLATRON W1941S
i know c.s can fix already , go option , video , display mode , set as widescreen , if still have a bit black side bar , go resolution to set it .
I don't know what you mean :/
I just wondered if you made a mistake reading the model number. One has an s and the other has a 5
is a same neither use old or new driver is still the same , the problem is window 7 . mayb nvidia can fix the driver problem or Microsoft of window 7 driver.
