My post is more of a question than a problem.  I picked up two Acer S230HL monitors to replace my 37" television/monitor I am now using elsewhere.  The monitors both use HDMI cables but I had to use a DVI converter for one of the monitors since I only have one HDMI port.  The graphics card I am using is a ATI Radeon HD 5800 Series and am running windows 7 x64.  

 

My original problem was a "black border" around the screen image on both monitors.  I thought this was due to a resolution issue of some kind from the source, but I found a setting called scaling or underscan/overscan that has removed the black border and given me a full picture.  I now have the scaling option set to 0%.

 

It seems as though my picture is fine now, but I am trying to understand why the default for amd catalyst control center is 7% for scaling.  Is this going to cause any performance issues.  Should I resolve this problem with a different method?  The picture still looks great but I would like to have the best possible image.  Full HD 1080p etc etc.  

 

Any knowledge or suggestions would be much appreciated.  Thanks in advance.
