Do not use Forceware 16x family drivers if you want to connect HDTV on Vista

I got serious trouble when trying to connect my new Quard Core machine to my new 1080p HDTV.

I recently bought a Samsung 40inch 1080p Full HDTV and also built a new desktop with Intel Quad Core Q6600 CPU + nVidia Geforce 8600GTS. Meanwhile I also have an Acer 19inch LCD connected as dual display.

The dual head output with 1920x1080 to HDTV and 1280x1024 to LCD monitor simultaneously works fine on Windows XP. But when I installed Vista Business version, I can't get it work correctly.

I downloaded and installed the WHQL ForceWare driver version 162.22 from nVidia's website. To my surprise. When I enable Clone mode in the nvidia control panel, the maximum resolution for both output becomes 1280x1024, which is somehow acceptable though not reasonable, because I remember I used to be able to set different resolution in even clone mode.
While I set the display to desktop extend mode, it allows me to set the HDTV to 1920x1080. But here comes the problem: now it suffers serious overscan. Tthe actual display area on the TV screen is much smaller than the the screen size and you can't let the TV to compensate this.

There is one way to compensate this, but I don't think that is a good idea: compensation means down-sampling thus blurring. I did some investigating online and found some others suffering the same problem. Someone pointed out that the 16x series driver is the killer. So I switched back to an 158.xx driver and it works as it should be!

PS: Seems both nVidia and AMD(ATI) still have long way to go to offer superb solution for Vista. Why you guys don't work hard and fast? Vista is a good way to attract non-gamers to buy expensive new video cards, but you want to earn the money, you have to provide good product. Hey, Haitao! I'm saying to you:-D
