Title: 360 1080i Scaling Question
Post by: darylzero on May 20, 2006, 08:59:00 PM

I have a Sony SXRD 1080p tv that will take a 1080i and upscale it to 1080p.

I am wondering if setting the 360 to the 1080i option may have any kind averse affects on games like slower framerates, etc.

Any help would be appreciated.

Id still go with 720p over 1080i. 720p is 60 frames, 1080i is 60 fields aka 30 frames. so your TV will basically display it as 1080p30. For slow games it would be good I would think but fast ones I think the frames are the important part.

720p, its a cleaner scale esp since most games are rendered in it and you tv is natively progressive.

I'd go with 1080i...

as paranoia4422 said most games are native to 720p however some games support native 1080i as well.

if a game supports 1080i natively that means it actually renders to that. other games that don't support it will render to 720p and be upscaled internally by the 360.

you'd only see "adverse effects" at 1080i over 720p if the game supports 1080i natively. However if a game DOES support that natively it's save to assume that it does because the console can handle it at that resolution.

So games that support 1080i and have some slowdown in spots might suffer a hair more at 1080i

I would imagine that the difference between 480p and 720p is far greater then the difference between 720p and 1080i in terms of how much processing power is required; and the negative effects moving from 480p to 720p are minimal at best.

I always recommend working at the resolution closest to your monitors native resolution. the SXRDs are 1080p machines so IMO 1080i will net you the best picture... and if it DOES have problems its just a switch in the dashboard...

thanks all.

i will mess around with it.  I haven't tried it in 720p yet, but my question was raised when I was playing King Kong @ 1080i and noticed some framerate issues...or so it seemed.  Now that may be an inherent problem with the game as like I said I haven't tried it in 720p.

Anyway, thanks for the responses.

I have the 50" version of that tv and I have my dashboard set to 1080i. To me the picture looks a little better than 720p and I notice no difference in frame rates or response times.

Games I've played on it

GRAW
DOA 4
FN3
PDZ
Halo 2

for the most part you'll be playing a game that's in 720p with the 360 converting to 1080i and then your tv converting again to 1080p. Less conversion is generally better so 720p directly to 1080p would be inherintely better. More so, going from progressive to interlaced to progressive is horrible. Stick with the 720p.
