My Samsung is actually the 407W LCD RPTV, not a Plasma :-(
It only has a 480p-capable Component input - no VGA...
As for sending 852x480, I can't believe how this question never gets resolved... My ATI 7500 only supports multiple-of-8 horizontal resolution (and verticle as far as I know). Hence, 856x480 and 848x480 are the two closest choices. I've heard rumors that the 9700 card with Catalyst claims to support 852x480 - but I've also heard that the card actually doesn't output that. This is being discussed in the Plasma forum on trying to get the 1366x768 Native Resolution of the Fujitsu P50 Plasma in case you are interested...
As you said, there is an option under the Advanced Settings of the ATI Control Panel which gives you Powerstrip like sizing/positioning controls. But as I said, these are grey'd out when my VGA connection is populated by my KD Transcoder. As soon as I hook up my old 17" MAG VGA display, those controls become un-grey'd and I am able to tweak position/overscan as you suggest. My conclusion - this tweaking is actually telling the display to do it - i.e. I doubt it's a function of the ATI card itself. I could be very wrong here, but I think from my description you can understand my conclusion. Please tell me I'm wrong and how to enable this feature when connected to the KD Transcoder :-)
Finally, even w/ Powerstrip, I am unable to fully correct for overscan. There is a portion of the image, on all four sides, which is clipped. It's quite a balancing act for me to get just enough of the image displayed so that I can see enough of the TaskBar and Icons...
Fortunately, SageTV has the means to adjust it's use of the Overlay so that I can see it's entire output. Don't know if my other App, ZoomPlayer, has a similar feature - would be nice...
