ATI Radeon HD 3200 (HDMI) + Samsung 3d LCDTV (1920x1080) underscan

Hi,

I have been building media centers (since XP MCE) for about a year now. Last month finally purchased my first big LCD TV. Last week, I bought an AV HDMI receiver (Pioneer VSX-520-K) and have spent the last week trying to finalize chaining all the components together into the best possible config. I am at 15m from the top of the mountain, but stuck there.
Bit of history...had an NVIDIA Geforce 7300 (DVI/VGA/Svideo) in the Mobo before, and this card was capable of using the full resolution of the TV, through VGA. Activating this PCIex card in the BIOS disabled my onboard ATI Radeon audio/video output. When I bought the AV HDMI receiver, I wanted to make use of the HDMI outbound sound, so took out the NVIDIA and activated the ATI HDMI onboard.
So config at that point is
Mobo send Audio/Video to Samsung TV over HDMI, sound is forwarded by the TV via fibre-optic cable into the Pioneer receiver.
Woohoo! Great sound - 5.1 in my speakers...but at first I noticed that the image quality was not as good as with the NVIDIA VGA, and them I noticed the underscan, 1inch black border lost across all sides.

In a lower res the underscan is gone, but the icons and edges are less clear. I know the TV can do better in its recommended res.

I did a clean W7 install to start with a clean system.
I think I have installed the correct ATI radeon drivers and CCC versions. Found lots of forums on the internet about this. An overview of what I already tried without luck...

ATI-CCC:
adjusting the underscan/overscan slider...the slider moves, but there's no change. When pressing okay - slider is reset to "0".
ironically, (can't remember how I opened it) there was a windows where I could make underscan/overscan changes in a white screen with 4 arrows in the middle (clikcing on the arrows would make in white area bigger/smaller and a blue border would appear around it, graphically showing the underscan/overscan change effect - THAT white window took the right size of the TV.

Samsung TV...
I read on a forum that setting the TV IN port's identifier to "PC" iso "HDMI/DVI" would solve this - FAIL

An option I will try tonight is buying a new HDMI cable, and setting up the following...
Media center -> both audio and video via HDMI through the receiver and receiver forwarding the video to the TV. Reason why I want to try this is that I have the impression that the TV is "telling" the ATI CCC console to perform the underscan, maybe with the receiver in between, this will not happen (will update this post tomorrow with the results)

Please help. I know I have a decent system, compare it to a high-powered WRC race car, got mud on my rearview window, and my wipers are broken...

Thx for all your input...

Hi all,

Just to let you know my problem is solved.
The way to do it was to use a freeware tool called "Driver Sweeper". ATI apparently is poor on the garbage-collect capabilities when removing drivers during CCC un-install.
I ran Driver Sweeper and removed all drivers and CCC stuff. After reboot, graphics seemed horrible, but after re-installing the latest 10_11 ATI suite all was fine.

Now got a crystalclear screen at 1920*1080 @ 60Hz
