Monitor not displaying native res full-screen

Can someone help me out? I've run out of ideas.

I'm running Win7 with a Sapphire Radeon 7870 and a Samsung 27-inch monitor. The native resolution on my monitor is 1920x1080, but I can't get it to display to the full screen size; i.e. it has black edges all the way round. It's the same in some of the other resolutions, but others, e.g. 1680x1050, display full-screen.

I've uninstalled/re-installed repeatedly Catalyst apps and drivers, also the screen driver. I've also tried re-installing with a previous version of Catalyst.

If I go to screen resolutions via the Catalyst icon in the lower-right taskbar (the little up-arrow that gives various icons) and go to available resolutions, it doesn't list 1920x1080. The highest one listed is 1680x1050.

If I right-click desktop and go to screen resolution, it shows the highest res as being 1920x1080, but like I say if I activate it, it doesn't go full-screen.

If I open the Catalyst app itself, it happily identifies the monitor and that the highest available res is 1920x1080. But I can't try switching to it within the Catalyst app (which they seem to have renamed and doesn't have that option anymore).

I've tried the scaling option within Catalyst, although AFAIK it shouldn't be necessary. But no go anyway.

Any ideas/suggestions?
