I have a Pioneer VSX 1021-K receiver and a Magnavox 40mf430b/f7 TV connected via HDMI to my Geforce GTX 560 Ti on Windows 7 64-bit Pro. When I first plugged them in I would get a horrible overscan problem so for the longest time I would just go into the Nvidia control panel and enable desktop resizing and resize it down to 1824x1026 to get the image to fit the screen. However lately I discovered that if I set a custom resolution in the control panel and use CVT Reduced Blank I could then get full 1080p and have an awesome picture. The downside to doing this is that I lose HD audio capability. For example with the resized desktop @ 1824x1026p I get DTS, DD+, DTS-HD, Dolby TrueHD, DD @ a max of 24-bit, 192khz but with CVT-RB @ 1080p I only get DTS, DD+, DD @ a max of 24-bit, 96khz. Mangix in the Guru3D forums pointed me here to this utility and I tried it out however with the HDMI audio extension I'm not even getting dolby digital. Maybe I am doing something wrong and you can help me out?

Audio data is transmitted during the blanking periods, so reducing the blanking reduces the amount of data that can be sent. You'll have to play around with the blanking/totals to see what the TV will accept without causing the overscan problem.

The hdmi-audio.dat file only includes basic stereo audio. You need a custom extension block that includes the other formats.

You can import this file as a starting point: http://www.toastyx.net/1080p-bitstream.dat

That includes the standard 1080p as a detailed resolution and the audio formats in the extension block.
