How do I get rid of black/gray frame around picture?

[bovinda]

Just finished upgrading my HTPC. Problem: on the TV display, there is a small black frame surrounding the entire picture, so the full display space is not being used. On my older HTPC (with a BFG 6800 OC), it made full use of the screen. How do I get rid of the frame around the picture?

I've tried: messing with the resolution, but the frame is always there even if I lower the resolution. The TV is a SD, old school, cathode-ray tube TV using an S-video input.
I've also tried: zooming in on the media center settings, but it doesn't change the frame.

My new hardware:
MSI 8600 GT 256 in dual display with TV and Viewsonic LCD (which is fine, no frame)
E2180
Foxconn P35A mobo with 2 Gb RAM
Vista 64 Home Premium

Any ideas are greatly appreciated! There must be some way to fix this.

My previous HTPC used Windows Media Center 2005 with a BFG 6800 OC out, also via S-video, to the same TV, and it made full use of the picture. What do I do?

EDIT: in case I wasn't clear, the black frame is around the picture on the TV at all times, whether I'm in media center or not.

I'm going to take a guess and say it might be a TV setting. Look in the TV's menu instead and see if there's any zoom or resize or whatever option in there.

Is the aspect ratio correct with your television, and also, is the output signal equivalent to the maximum (or at least a supported) resolution?

Clickynext -- there's no resize or zoom option on the TV. What makes me think it's not the TV is that it displayed perfectly before I upgraded the graphics card and other components on my HTPC.

Syntax -- I'm assuming the aspect ratio is correct, mainly because the black borders are even all around and the picture doesn't look stretched either way. I'm not sure about the output signal though--how do I find out about that? I've tried adjusting the resolution from within nVidia's control panel, but it does nothing to affect the borders, just the amount of the picture that's displayed within the black frame.

Any other ideas?

It's a shot in the dark, since I don't have a similar setup, but isn't there an option to "stretch" to Full Screen, regardless of the resolution...?

I believe I've seen the setting called "use my monitor's built-in aspect ratio", or "fill the screen" from within the driver...

Good luck!
