Black line around screen edge

Clarkson · 23 Jan 2011 at 11:20

Hi, I have suddenly found myself with a black line around the edge of my screen, most prominent at the sides and bottom.

I use my HDTV as my monitor, and normally everything fills the screen right to the edges. However, I went to start up lost planet 2 but on the main menu screen my mouse/keyboard/gamepad all failed to have any effect, so I ctrl+alt+deleted and logged off. I then logged back in and the black line around the edge of my screen had appeared. I then restarted my computer to see if it would fix it, but no good.

I have a 6950 GPU and run windows at 720p for desktop use.

Anyone got any idea why I suddenly have a black line about 0.5cm around the edge and how to fix it?

thanks.

go into the catalyst control centre for your 6950 and there's a tab in there for screen size adjustment for a tv output

I find it looks best on mine when set to overscan rather than underscan - that puts the screen edges about 2mm past the edges of the tv screen

Yup its overscan you need and make sure you have an updated driver. It was an issue a while back and even enabling it would do nothing. Just update your driver then proceed to the overscan setting. AS MUCH AS I Admire ATI ... this option was made hard.

Howdy, yes I found through google it could be overscan and I think its back to normal now.

The settings for it were pretty well hidden, hiding behind the click of a small black arrow next to another picture. Not the best layout of settings there.

Not sure why it even went to underscan in the first place but at least I know how to fix it if it happens again.

Cheers.

It defaults to underscan just in case there's a faunt that would cause you to not be able to see your whole desktop area - that would make it near enough impossible to use the machine to fix the issue if you didn't know any keyboard shortcuts etc...

something like that anyway lol - it's more "guaranteed" to fit it all on the screen with underscan rather than overscan (you can make your own reasons up, like I did lol)
