I don't suppose there is much difference:

vs
http://www.digitalyes.com.au/prodView.asp?idproduct=19872 (Same card, 
different branding - even has the same ugly green sticker)

Ok, this one makes sense.  As a matter of fact, I have this one as one 
of my modelines, only in the single line format, except for negative 
syncs instead of positive.

        ModeLine     "1080i" 74.5 1920 1952 2016 2208 1080 1084 1096 
1126 -hsync -vsync interlace

Now this one intrigues me.  It is named "1080i" but is in reality a 
1760x960 format.  I'm surprised that this is being accepted for HT1080i 
output.  Lines like that give me the "Not a valid TV Format" error.

This also intrigues me.  Not sure what this does...  I see it is for 
calculating DPI, so it should be the size of your TV.  This would give 
12.6" x 7.1", or 14.5" diagonal.  Somehow that doesn't seem right.

I also don't understand this.  True, the only allowable values are 
SVIDEO and COMPOSITE, but does this mean you must specify COMPOSIT even 
for component outputs?  Or is it simply ignored when TVStandard is HD1080i?

Looks like "in1080i" is a leftover from Jarod's guide.  
/var/log/Xorg.0.log probably would show this one being rejected, since 
there is no ModeLine for it.  Probably also "1600x1200" (should probably 
complain about being too tall).  "1280x1024" is the mode that I get 
stuck with when I have no modeline at all.  It is nearly the right 
height, but obviously far too narrow.  I wonder if it is also rejecting 
the "1080i" entry?

This is the virtual screen size.  It is probably being overwritten to 
the highest resolution that is accepted above (probably 1920x1080).

As it is, I'll give the positive sync version of 1920x1080 a try, as 
well as the "1080i" that is really 1760x960.

Thanks for passing this on!
