Rasplex Adjust Aspect Ratio or Zoom Level?

So my current setup is: 

  • Rasplex connected to my Panasonic with HDMI cable VIERA TC-L42E50 42-Inch 1080p 120Hz
  • My TV display is set to 16:9 aspect ratio

The problem is that the display is still zoomed in (it cuts off the text on the sides). Is there a way to adjust the display setting on Rasplex? I looked around in the settings menu with no luck. Maybe I just missed it, or can i change the setting if i ssh into my Rasplex?

 

Any Ideas would be appreciated!

 

 

You can adjust the zoom level in the Appearance settings, IIRC.
