Sun monitor

[mai at ms.uky.edu]

I have a 19in BW monitor. But the screen leaves more than 1/2 in at each
margin. (I have seen some worse than that). My question is: how do I
adjust the size of the image? I cannot find H size V size and/or center
adjustment usually found on back of a TV set. (Only a brightness
ajustment) The monitor is made by Phillips of Canada, in March, 90.  I
would guess it can be done by take off the cover and find some adjustment
inside. But I would like to hear from experts before doing that.  I
noticed the image is not as sharpe on the edge but I do not care.
