Brion, thanks for the help and the links.

After much fiddling around I have come up with the following xorg.conf
that gets me a hell of a lot closer:

Section "Monitor"
    Identifier     "Monitor0"
    VendorName     "Unknown"
    ModelName      "Unknown"
    HorizSync       30.0 - 110.0
    VertRefresh     50.0 - 150.0
    # Option         "TVStandard" "HD1080p"
    Option         "TVStandard" "HD1080i"
    # Option         "TVStandard" "HD720p"
    # Option         "DPMS"
    Option         "DPI" "100 x 100"
EndSection

Section "Device"
    Identifier     "Device0"
    Driver         "nvidia"
    VendorName     "NVIDIA Corporation"
EndSection

Section "Screen"
    Identifier     "Screen0"
    Device         "Device0"
    Monitor        "Monitor0"
    DefaultDepth    24
    Option         "metamodes" "1920x1080 +0+0; nvidia-auto-select
+0+0; 720x480 +0+0; 800x600 +0+0; 640x480 +0+0"
    SubSection     "Display"
        Depth       24
        Modes      "1600x1200" "1280x1024" "1024x768" "800x600"
"640x480"
    EndSubSection
EndSection


Couple of items to note (using ASUS M2NPV-VM Mobo nVidia GeForce 6150):

1. Connecting via DVI - HDMI cable does not work.
(WW) NVIDIA(GPU-0): Unable to read EDID for display device CRT-0

2.  Using component cables does work (EDID).

3.  My TV is capable of HD1080P, but adding:
    Option         "TVStandard" "HD1080p"
- Results in a fall back to 800x600 or such resolution and washed out colour.

    Option         "TVStandard" "HD1080i"
- Provides me 1920x1080 resolution

    Option         "DPI" "100 x 100"
- It wanted 75x75 DPI, but I was able to up it to 100x100.


Running in "Unscaled" mode on the television results in a very
annoying line of the far left of the screen about 1 cm wide that
almost looks like the screen has wrapped around (though it has
different text in it).  Not sure how to get rid of that.


Some some final questions:

1.  Is the GeForce 6150 capable of powering a HD1080P picture?

2.  I thought DVI-HDMI (digital) was superior to Component (analogue).
 Is this true and should I be able to see a difference (assuming I got
it to work) between the two?

3.  Should I take up these problems (EDID with DVI and so on) with
nVidia on their forums (http://www.nvnews.net/vbulletin)?

4.  If I am taking the plunge into HD content, was is a suitable
amount of RAM?  I currently only have 1 Gig, which I was planning on
increasing to 2 Gig.   I do a lot of transcoding (for the PSP and
xvid).  Should I make it 4 Gig?

TIA,
Dave
