Media Browser has configurable settings to compensate for overscan issues. This only affects a small percentage of people. If you have no issues then do not change any of these settings.
Overscan issues can be:
- GUI elements, such as buttons, shown partially offscreen
- A blue border visible at the screen edges
The correct settings, depend on your display. This guide acts as a starting point for troublehsooting overscan issues.
In the MediaBrowserXml.config file there are several settings that can be used. The config file can be found in “C:\ProgramData\MediaBrowser” (this folder is hidden in windows by default).
Open the MediaBrowserXml.config in notepad and look for the following settings:
<OverScanScaling>
<X>1</X>
<Y>1</Y>
<Z>1</Z>
</OverScanScaling>
<OverScanPadding>
<Bottom>0</Bottom>
<Left>0</Left>
<Right>0</Right>
<Top>0</Top>
</OverScanPadding>
Adjust the X, Y Z and Bottom, Left, Right, Top settings.
Examples
OVERSCAN
Here you can see the config icon in the top right is nearly offscreen. To correct this you would increase the values of the Bottom,Left,Right,Top elements until the backdrop appears properly on your TV/Monitor.
so for example you would change
<OverScanPadding>
<Bottom>0</Bottom>
<Left>0</Left>
<Right>0</Right>
<Top>0</Top>
</OverScanPadding>
to
<OverScanPadding>
<Bottom>27</Bottom>
<Left>47</Left>
<Right>47</Right>
<Top>27</Top>
</OverScanPadding>
UNDERSCAN
In this image there is an unsightly blue border visible around the entire backdrop. To correct this you would decrease the Bottom, Left, Right, Top elements until the backdrop appears properly on your TV/Monitor. If the value is already ‘0’ for an element, you would use negative numbers
to correct this you would change
<OverScanPadding>
<Bottom>0</Bottom>
<Left>0</Left>
<Right>0</Right>
<Top>0</Top>
</OverScanPadding>
to
<OverScanPadding>
<Bottom>-24</Bottom>
<Left>-45</Left>
<Right>-45</Right>
<Top>-24</Top>
</OverScanPadding>
CORRECT
This is an example of a properly adjusted image
What the numbers mean
When you adjust the OverScanPadding values in the MediaBrowserXml.config file, you can correct any overscan/underscan problems you are experiencing.
As you increase the number in one of the borders (Top, Bottom, Left, Right) it will stretch that edge of the background towards the edge of your screen. If you increase the value too much, you may have controls drawn offscreen. In which case you would just lower the number for that particular edge.
As you decrease the number, it will shrink the image away from that particular screen edge. You would do this if buttons or menus are drawn outside the screen edge.
