Why does 1080p output to HDTV bigger than the screen?

post #1 of 14
Thread Starter 
I have my computer hooked up to the new HDTV I got, its 1080p but when I set the computer to output 1080p, it fills up more than the screen, leaving the outside edges of the image an inch or two outside the screen if that makes sense. I know about overscan on crt's but didn't think this would be an issue for the LG 47Le8500 I purchased.

Most TVs have SOME issues with HDMI connections that should easily be disabled.


Go to TV settings and disable over/underscan. If you can't find that, it might also be titled "Just scan"

If all else fails, use VGA or DVI.

Change your video cards over/underscan settings in your GPU control panel.

The TV is doing improper scaling of the signal, ergo to fix this you change the TV settings. Try the different 'fill' or 'zoom' modes. You need 1:1, or no scaling, basically.

I had fixed this by running a really strange custom resolution, but your solutions sound much more...professional. Thanks guys.

This phenomena is called ''Overscan''.
Link:http://en.wikipedia.org/wiki/Overscan

Different HDTV manufacturers have various methods to overcome this issue. For your LG 47LE8500, you go into the MENU (see picture 2 below taken from page 51 of the User Manual) and change the Aspect Ratio to Just Scan (marked by the red arrow).

This is what is recommended in page 128 of the Manual (see pic 1 below)

sweet! thanks guys! I saw that setting on the tv, but thought the issue was from my PC's side. Now I am wondering if there is a way to sync the games at 120hz refresh rate since my tv actually does 240hz!

unfortunately it doesnt do 240hz, common marketing gimmick, the most it will accept is 60hz and then from there its down to the tv manufacturer to add some effect such as backlight flashing to supposedly improve the motion, some people like the effect but your best off leaving all the motion plus etc features off

Well I can tell you one thing, with it enabled, the motion on the screen is super smooth and with it disabled its jerky and studdery. Why would it be best to leave it off? I disagree with it being a gimmick.
