I have a Syntex Olevia 32" LCD TV (model #LT32HVM) and it says it supports 720p and 1080i, but no mention of 1080p. This really doesn't surprise me as it is relatively 'cheap' for a HD set.
Anyway, I was reading this article comparing 1080i and 1080p (link) and near the middle it says: "As opposed to tubes, microdisplays (DLP, LCoS, and LCD rear-projection) and other fixed-pixel TVs, including plasma and LCD flat-panel, are inherently progressive in nature, so when the incoming source is interlaced, as 1080i is, they convert it to progressive scan for display."
So that does that mean my LCD TV really displays 1080i in progressive scan therefore making it 1080p?? But if so wouldn't they say that in the specs? And can you even tell the difference between 1080i and 1080p?
Thanks

There aren't that many 1080p TV's at the moment, but should have a bunch of them coming out soon and becoming more affordable. AFAIK, I don't think the Xbox360 supports 1080p, although the PS3 supposedly does.
Most people can notice the difference between interlaced and progressive.

A 1080p lcd display will have 1920x1080 pixels... Your lcd does not.

To asnwer your SPECIFIC question. Yes, LCD's are progressive in nature, and the image it displays won't be interlaced. But it acheives 1080i through a 1366 x 768 resolution... basically it will handle a 1080i source but it can't display 1080 lines.

Interesting... thank you for your response. So my TV basically displays a 1080i signal in 720p? It seems 1366 x 768 is slightly higher then 720p though.

I believe that the Fall Update gave the xbox 360 1080p resolution, but only if you use VGA cables (not through component, I don't believe 1080p is possible through them)
Component does have enough bandwidth for 1080p (my LCD accepts 1080p through VGA, component, HDMI, and DVI)
If your tv can "accept" 1080i but not 1080p, you most likely have a 720p native LCD. If that's the case, 720p should actually look better on your display than 1080i.
1080p does have its advantages, but the 360 doesn't really make much use of it yet, besides HD-DVD playback.

So what if I connect low-definition sources; like s-video or composite? Since its progressive in nature, do both of those render in 480p? Or do I still NEED to have component cables to achieve that resolution? But if the LCD does not display interlacing, is there a difference if say I connected a DVD player with S-video versus component? Would both cables display in 480p?
480p, 720p, 1080i, and 1080p are only possible through Component, VGA, HDMI, DVI, and Scart (<--not sure what exactly what that one supports, it's a euro thing)
S-video and composite (yellow plug) can only do 480i.
Even though LCD's are progressive by nature, they can display 480i images by de-interlacing them with their internal scalers. Some LCD's have issues with this however that make the image not look as good as on a CRT, so most of the time you want to be in progressive scan mode at the highest res your display supports.
The games for the 360 will always be rendered in their default resolution by the GPU (which most of the time is 720p) and then good 'ol Ana (the scaler chip) will scale the image to the appropriate resolution (downscale or upscale, depending on what res you are going to) and output the image via the the a/v multi-out port.

Very interesting... thanks for the insight. The nature of my question is in regards to the GameCube (dare I say it in this forum!) I was debating on just playing using S-video as I have been or shell out the $60+ on ebay for the ultra-rare component cables. So i guess component would make a big difference, now I just have to decide if its worth it to pay that much for the GC cables!
Component cables for the cube do significantly improve the overall look of the games (IMO) and I remember getting my cable for $30-$35 or something. That was back when Lik-Sang was still in business though.
