Emby for WMC is not displayed on 100% of the screen. How to troubleshoot overscan issues.

Recommended Posts

UPDATE (4th Nov 2013):

 

Sometimes you may have to edit the Windows Registry as WMC is configured with margins, which may lead to the "blue border" effect.

 

If you are willing to edit the Windows Registry, here is what is needed, but this is done at your own risk ! The MediaBrowser3 Team accepts no liability if your Windows Registry is unusable after the edit.

  • Run regedit and go to HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Media Center\Settings\MCE.PerUserSettings.
  • Change the Margin Saved value to 1 and change all the other margins (top, bottom, left and right) to 0.

This not only fixes the blue border seen on MBC but also fixes the issue with the margins of WMC being set in too far which is what makes TMT 5 not fill the screen when loaded as an external player from MB3

 

For XBOX issues, please see the following post.

 

If after changing the registry you still see the "blue borders", please follow the instructions below.

 

"Blue Borders"

 

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 MBCommonXml.config file there are several settings that can be used. The config file can be found in “C:\Users\username\AppData\Roaming\MediaBrowser-Classic\Configurations”.

Open the MBCommonXml.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.

First, if seeing the blue underscan border you can also try going into Media Center Tasks > Settings > TV > Configure your TV or Monitor > Change type to Monitor or Projector. Selecting TV will give underscan borders.

If the above did not rectify the issue 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.

If you see a blue border on your XBOX extender, the following may help (thanks to @@buddyweiser) .

Open regedit on the PC extending to the 360's

 

Navigate to the HKEY_USERS and take note of all of the users.

 

Then, go to one of your xbox 360's and open windows media center.

 

Leave it open, and return to your PC.

 

At the top menu, click on View, and Refresh. Note if any new HKEY_USERS appear. 

 

If you have a new one, that is the registry for the xbox in question (NOTE: You might have to do this for each of your extenders).

 

Once you have the registry for the xbox 360, you can then navigate to Software\Microsoft\Windows\CurrentVersion\Media Center\Settings\MCE.PerUserSettings.
