Help for 1080p (1920×1080) black border full screen issues over HDMI

Some HDTVs leave a black border around an HD 1920x1080 image

There seems to be an issue affecting many people whose HDTV does not display a full screen 1080p image when connected to a computer over HDMI.  It goes something like this…

  • Excited person buys 1080p HDTV with dreams of experiencing PS3/Xbox/PC/Mac 1920×1080 viewing heaven
  • HDTV duly arrives and gets setup
  • HDTV connects happily over HDMI and displays 1080p but with a black border around the edge of the image
  • Excitement fades as the 42 inch TV is only displaying something like a 38-40 inch image

I’ve seen this on many LCD TVs, and not only those offering 1080p resolution.  I used to have a 32 inch screen with a native resolution of 1366×768 and it would do this.  My current 42 inch LCD screen, which is a Vizio SV420XVT1A does this too.

If you have spent hours playing with video card or game console setting to no avail, do not despair – there may be an easy solution!

The image now fills the screen

Most LCD panels have settings buried in their menu which allow the user to move and stretch the image being displayed.  These menu settings are sometimes described as Horizontal and Vertical Size and Horizontal and Vertical Position; often in the menus the orientation words are reduced to H and V, which helps to save space but not confusion.

In both of my cases I have found that by increasing the horizontal and vertical size of the image I was able to fill the panel with a pin sharp full screen image.

Some TVs have zoom settings which allow the image to be resized in broad steps, but I find the small increments of horizontal and vertical resizing can deliver a more accurate image fit to the panel.

Check out the gallery below for the steps I followed on this Vizio SV420XVT1A.

    • Yes this overscan/underscan solution will work if your graphics card has those options. As you mention these settings are available for some ATI cards in Catalyst Control Center and I’ve used them myself in the past to resolve this issue.
