The modes in BOLD face are all VESA modes at 60hz. 1920x1080 is not a VESA mode, that's probably why it's not "recommended" but I guarantee it works, assuming you have the right horiz/vert frequency.
When I say it's "1:1", the SXRD panel on this TV is 1920x1080. If you feed it a 1920x1080 signal, that's exactly what you get, 1:1 pixel mapping. YES the edges are cut off by the bezel/frame (that's what "overscanned" means). If you choose the "Normal" Wide Mode (pg 22 of the manual), it will shrink the PC screen so you can see the whole thing (ie "underscanned") - it does put pretty significant black borders around the image though. If you want the image to come closer to the edges (less black border, there will still be some border though, that's unavoidable because this TV naturally overscans the SXRD panel, nothing you can do about that... well short of internal modifications..) you can use the Nvidia/etc drivers to create a custom desktop like Hughmc talks about. Note this is pretty much the only way to see the whole PC desktop, if using HDMI input.
Hope that clears that up..

Thanks, Walk... that does indeed clear up the question of whether or not 1920x1080p is functional on VGA, albeit with "issues". (I'm aware of this set's 1920x1080 panels and what those benefits are, moreover.) But I have to take exception to the notion that the VGA input is giving you 1:1 pixel mapping. By virtue of the fact that the VGA input is deliberating zooming the display out (underscanning, thereby creating black bars on all sides), it negates any benefits of 1:1 on the A3000 (same as if there was a service menu control similar to the A2000 that would allow us to eliminate the overscan in the HDMI inputs.) This is what I meant when I said that there was software available (such as Media Center) that will allow one to retain 1:1 pixel mapping when playing BD or DVD while only adjusting the overscan of the desktop.
I'll concede that the specific Xbox mentioned earlier could possibly be displaying improper horizontal/vertical frequencies, though I have seen up close other Xboxes display 1080p via VGA into the A3000 fine, save for the deliberate, permanent, and irritating windowboxing and some intermittent drop outs at that input. Looks like TreyS will have to explore those settings further. But what you're describing (the initial overscanning of 1080p info and using software/drivers to underscan the desktop) is attributable ONLY to the OTHER inputs on the A3000 and NOT the VGA, which is where the initial discussion was. The windowboxing (underscanning) on the VGA input is permanent and can't be fixed. So, not only is there no 1:1, again I do not see how you're able to accomplish an overscan (let alone a full border-to-border screen) on that input no matter what adjustments are made or software that's used. Even the manual indicates that this is not possible.





















With a straight face, even.
