I was just wondering, how does an LCD support 1080i and 1080P with a resolution of 1680x1050?

I just bought the Sceptre 22' and I would like to know if it would be beter to run it at 720P or 1080i from Comcast digital cable.

Also, what resolution should I output for a software upconvert on this display?
 
My hunch is that you'd be better off downscaling from 1080i rather than upconverting from 720p. I could also be completely talking out of my arse, though. Is there any reason you can't try both and decide for yourself which looks better?
 
I would say 720p because:

1) I think your monitor won't take 1080i.
2) I think hd broadcasts are in 720p to start with.
3) Interlace = bad

You should upconvert to 1680x1050
 
DVD movies are in 16:9 format, whereas my monitor's resolution is 16:10. IF I upconvert through software, I want to keep it 16:9, so I guess 1280 x 720 would be best huh?
 
the 16:9 issue would be if your monitor supports aspect modes like fill, 1:1 pixel mapping, or aspect mode (keeps video scale). It shouldn't make a difference between 720p vs 1080i for this because both are 16:9.

I would try both and see which gives you a clearer picture. 720p would have to be stretched to 1680x1050 so it won't look as crisp. 1080i will have to be line doubled to be progressive and shrunk to 1680x1050, again there will be some quality loss. So try both and see which one looks better
