Monitor display

[Stephen]

I'm sure this is an easy one. Sent computer in for
unrelated problem and when it came back the display on
the monitor is too small i.e. there's a half inch black
border all around whichever window is open. Went to
Display Properties, Desktop, and tried switching between
Center, Tile and Stretch but nothing happened. Thanks
for your help.
