I thought I read that there was an update to the 360 that allowed 1080P mode.

I have a Sony V2500 TV thats 1080P but it says that it only supports 1080i over component. The TV has VGA input but it doesnt say 1080P through that, but instead some weird resolution like 1800x 1055 or something just below what 1080P would be (1900x1080).

I dont have the disposable funds now to buy a VGA cable just to test it out - but whats the deal with the 360 and 1080P?

Also I was looking at HD-DVDs yesterday and a lot said 1080P on the back. Thats pretty damn friggin worthless if the 360 is only going to do 1080i.

1080p works over component and vga just fine, a lot of the issues are with the tv not accepting the signal. I suggest you try the vga cable as others people have had success with 1080p. The resolution is limited in the manual but some people have gotten 1080p to work. I have a 47" Wesinghouse and 1080p over vga looks amazing.

Trying it involves wasting money at the store. Unless Best Buy sells them and will take the return without restocking maybe?....

Just to note, HD-DVD's are limited to 1080i over component. But your tv should de-interlace the signal properly.

Probably a newbie question for another forum here but if the TV deinterlaces the 1080i signal does that make it just as good as a 1080P signal? Or is it like a half-assed 1080P signal?

For that matter, does that mean even though the TV says 1080i, its actually deinterlacing it automatically anyway?

A properly de-interlaced 1080i signal will be every bit as good as 1080p. That tv's native resolution is 1080p, so all input signals are scaled/de-interlaced to 1080p. Sony's are known for there excellent video processing, I think you will be ok.

For HD-DVD purposes, 1080i is 100.00% identical to 1080p.
The movies are stored as 1080p24 and are converted to 1080i in the player during playback. (Google up "telecine" for details.) Setting output to 1080p means the deinterlacing is done in the player instead of the TV. This might make a difference if the TV had crappy deinterlacing but 1080p displays appear to have uniformly good deinterlacers so it doesn't really matter where the deinterlacing takes place.

For games it might make a very slight difference on games that run at 60fps. For games that run at 30fps it should make essentially none.

The primary reason to prefer 1080p via VGA is that VGA ports don't normally get overscaned, whereas component (and HDMI) are by default overscanned by most TVs.

The Sony Bravia 40W2000 will accept the XBox 360 1080p output via VGA component only, and not via Component. Initially it says "Unsupported Resolution" but you can remove this message, and it displays OK. There is a small amount of "pixel jitter".

Sadly for us in Europe and Aus, the VGA link is 60Hz only, so if we want to watch 50Hz SD DVDs we have to use Component, where DVDs are replayed at 576/50p. If we use VGA we get them scaled and frame repeated to 1080/60p - which has unwatchable motion judder.

(And don't get me started on Media Center Extender mode - which in HD is permanently in 60Hz whether you use component or VGA...)
