I am very curious about this.. I am hoping to set up my PC in the living room this weekend to try playing oblivion on the big screen... I was surprised that they recommended 1024x786 in the manual when I *thought* the native rez was 1280... I would prefer to do it through the HDMI rather then the VGA.
The native res of the set is 1280x720. I imagine they recommend 1024x768 to eliminate any concerns of overscan from the outset.
To answer the original question, use your video card drivers or Powerstrip to do a resolution-within-a-resolution. In Nvidia drivers, you can go to the custom resolution page and set the timings manually. Basically you end up with a slightly lower resolution being sent in a 1280x720 timing. If you were able to turn your overscan down to zero (I haven't looked in the service menu to see if this is possible, but it's really not highly desirable), you would be fine with the 1280x720 res.
As for the VGA working, this is because the Samsung is doing something similar (although in a lossier way), in that it is scaling the signal it's receiving to a slightly lower res as you change the image size with the controls.
I think the only thing you'll really lose from using the HDMI input for the PC is the ability to control the image on the TV side. Luckily there are more than enough tools to do this on the PC side, including most current video card drivers.
