Windows 7: Black border around screen

23 Apr 2010   #1

Black border around screen

Hi there.
Just updated from W7RC, where I was running both of my monitors (Benq 24" + 19") on extend desktop - had no problems at all.
I am now running Windows 7 Ultimate (OEM), and I have the same graphics card (ATI Radeon 5770), same RAM and same CPU. I have a new motherboard and new HDDs.

I've managed to get it so that the desktop is extended the right way, however, this black border was not around last time and I can't figure out a way to get rid of it.
The settings I was able to use last time (in the monitor's menu) are no longer accessible, and Catalyst gives me no options to brute force override.

How the hell do I get rid of this black border!?

Hi rsjabba,

Could you please upload a screenshot so we know exactly what you're seeing?

This actually looks nothing like what im seeing. I have a feeling a photo would better show it... unfortunately right now I haven't the means of acquiring one. When I've installed everything, inc. my webcam, I'll take a picture.
Basically, the black line under the left window is a part I've never been able to access - its the dead space resulting from two differently sized monitors.
Around the screen on the right is actually about a 1cm (1/3in ish) on the bottom and top of black border and about 2cm on the sides.
The monitor and GPU report that it is on 1920*1080, its native res, but it looks like it is at a lower res, with the text being slightly blurry as it is when you run your monitor at a res that is not native.
But I have absolutely no idea why it would do it in the OEM but not the RC?

Actually when I look at it now the black lines on the right are somewhat visible.
Still, how do I get rid of them?

You may be describing ATI's OverScaling. Depending on which version of Catalyst you are using, the setting is not easily found.

Right Click one of the displays. Choose configure, Scaling Options. Drag control to happiness.

Thanks for the screenies, but no luck. I can't drag that bar, as it is disabled. I never had to do any of this in the RC version, everything just worked.
I've even reinstalled Windows to see if it was just a crap install, but it wasn't that either.
Im stumped.

Casca, It might be that Its 5am and I've had a long day (and a longer night) but slowing down and rethinking what you showed worked.
Black border gone - it was the overscan thing.
Now that this issue is sorted, I'm going to bed - but thankyou so much for your help!
