720p to 1080i

1080i looks better to me...

anyways dont forget 360 can do 1080p now via component...is there a list of tv's that accept 1080p via component?
 
720p looks better depending your set. Ony my TV interlaced images look bad, thus I'd rather use 720p.
 
Guys, this is all about display type. Which you should use is just dependent of your display. Fixed-pixel displays (LCoS, DLP, LCD, plasma) only display progressive scan. If you have a set with 720 vertical pixels, you can input 1080i all day, but only 720 vertical pixels will be displayed. Likewise, tube-based sets (CRTs, tube projectors) will only display 480i, 480p and 1080i. You can input 720p, but it's going to display 1080i, artificially creating the extra lines. It will not display 720p, no tube can.

In short:
Fixed pixel displays ONLY display their native resolution, regardless of the inputs they support.

Tube-based projection sets ONLY display 480i, 480p and 1080i, regardless of whether they support 720p or not.

If you have a CRT or tube RP, use 1080i. If you have a fixed-pixel display that's not 1080p, use 720p. If you have a 1080p fixed-pixel display, use 1080i (or 1080p, if available).


As far as which source is better, that's the only question of preference. 1080i will offer more detail and clarity, while 720p will have smoother motion.

The newer Samsung TVs can do 1080p over component.

That is great news. Thanks a lot. I guess I will pick up a new Samsung then.
 
Though plenty have mentioned that they prefer one or the other, it's only an accurate comparison if you compare a 720p TV to a 1080i TV. The picture will always look better when set to the TVs native resolution. If you set it to 1080i on a 720p TV the TV will scale the image to 720p and it will look worse than when set to 720p in the first place. Vice Versa is true of a 1080i TV.

Going along with this, I haven't seen anyone mention that almost all 360 games are developed in 720p. So why would anyone want any resolution different than that, forcing a conversion?

From what I've heard the 360 has an excellent scaler built-in. It's far better than what most TVs have in them. The primary reason to buy a 1080i TV is because they are cheaper, so if you can get a pretty damn similar image for much cheaper, why wouldn't you?
 
I'm running 1080i on a 32" CRT and I always, always get a big WOW out of anyone that comes over and doesn't have an HDTV. I wouldn't let native resolution of the TV affect my decision. I'd check reviews of any specific models I was looking at to see what 360 owners said.
 
Now I have a HD projector and I am getting ready to connect it now. I was wondering how it stacks up against HD televisions. I have a Hitachi CP-S318 and I don't really know anything about it. It is in working condition, but I just wanted to know if it will give me good quality compared to a 720p LCD screen.
Could anyone help me? I'm trying to find more info on my projector, but I'm not having much luck.

It's not an HD projector. It has an 800x600 resolution, HD is 1280x720 or higher. It will be downscaling the 360s 720p down to 800x450 (to keep the widescreen ratio).
 
thanks man because i was really wondering about that and I have almost no HD knowledge. It will still make a fairly decent picture for the 360 that's better than regular tvs right?
 
You gain a few more horizontal pixels and lose a few vertical pixels, or you can display it at 600x480 (standard definition). So no, you don't gain any picture quality from standard definition.

800x600 projectors are made more for business presentations than they are media and games. That projector is not HD.

Get a HD projector or get a different set. If money is a huge issue, check Craigslist for a cheap rear-projection set.

Why?

You have no idea how many projectors have been purchased because people have come over and seen the image my InFocus 4805 that only does 854 x 480 can do.

I am retiring it this week though, as I just bought a Mitsubishi HD1000u 1280x720 projector, which just dropped $500 and I was able to get it for $860. Where else are you going to get a plasma like 108" HD image for $860?! I'm stoked.
 
does the x360 require the vga cable to output better than 720i/p resolution? and if you go with just the component cable do you need to switch a setting on the tv too or does the tv just display whatever is coming out of the 360?

Depends on your tv, but usually no.
 
I would suggest listening to the Major Nelson podcast where he breaks down HDTV. For once it's not littered with MS propaganda and spin - it really makes sense. Here's the link:

My advice - try to set your Xbox 360 to display in your TV's native resolution. For example, if your TV is a native 720p set and you set your display to 1080i, your TV will have to convert the signal and can cause a slight lag. Not enough for movies and television broadcasts to notice, but it could mean life and death in Geometry Wars.

seconded. if in doubt, i'd set it at 720p and forget it... since most games are (supposedly) optimized at 720p, that's where you'll probably get the best results for a smooth framerate anyway.

plus, in general terms, 1080i is best for still scenes (little movement), 720p is best for fluid action (the i is for interlaced/not every line is drawn on the screen at once, the p is progressive/every line on the screen is drawn). I don't know about you, but I don't play many games that have no movement.

I have to second this. I have a Panasonic AE900U which gives me 720p native at 16:9. Nobody can touch the screen size I have for the price paid.
 
Great info. Just to bring this up again it really depends on the TV. Everyone told me not to use the VGA cables on my 360 becuase it will wash the colors out, but on my Samsung DLP the VGA running at 720p looks ten times better then the component at 1080i.

The talk about "native resolution" is really interesting. I need to try running my HD cable box at 720p and see if the picture looks better than 1080i.
 
Depending on your set, 720p looks better. If you're buying a set don't get a set that just does 1080i unless its REALLY cheap.
 
Has anybody tried any aftermarket (Monster, Psyclone, etc) cables and if you did could you notice a difference over the MS cables that comes with the 360.
 
I've got the X360/HDDVD hooked up to my Samsung HL-S5687W with VGA set at 1080p ....all the games and movies are running at 1080p and look absolutely badass....

Be careful on that "extra lines" business -
If ONLY my HDTV created artificial lines (ie, had an upscaler). My Sony HDTV is a POS that downscales 720p to 480p. This, combined with the PS3's lack of an upscaler (and most of the games being 720p) is pushing me towards actually buying a 360 so I can finally have some HD content. I've had my HDTV now for 3 years (I did get it fairly cheaply at the time, about $1200 for a 51" in Oct 2003). To this date all it has been is a nice big SDTV, with some 480p gaming with the PS2 and GC thrown in (and of course pro scan DVD playback). I'd like to finally see some HD on it! That was *supposed* to be via the PS3, but now, who knows (if they revise that hardware or start mandating all games be 1080p, and thus i, I will be OK). But I'm seriously considering a 360 now.

Completely off topic - I waded into this forum looking for info on a revision for the 360 I heard about - a new chipset or something? Is this something I should wait for?

revision for what?
 
This isn't directed to people who can't get either one, or would just like to brag that they can get 1080p. This is to the people who can get either one. Which one do you prefer? I currently use 1080i, but I don't even know if 720p would be any better.
 
1080p baby!!

Oh wait...my tv doesnt do 1080p.

Honestly, I can't tell the difference between them...nor do I even know which one my tv is currently set at :lol:
 
I really do not know. My TV supports both so I just throw it on at 1080i.

I can tell the difference easily between 1080p and 720p but not 1080i compared to 720p. It's weird.
 
My TV's an HD.. but it's not widescreen.. so 720p and 1080i automatically go into widescreen but I get the edges of the screen cut off. :(.. but I leave it at 1080i.
 
this has been done to death, but its a fun discussion


in 720P there are 720 vertical rows of high def pixels

in 1080I there are 1080 rows of pixels but only every other row is HD the ones in between are interlaced SD. therefore only giving you 540 (half) rows of HD pixels, while the other 540 SD rows appesr almost blurred compared to the HD ones.

720P looks better.
1080P looks best though.
 
I voted 1080i but you can't see a noticeable difference outside of still text between 720p and 1080i.

Oh and I have a 1080p TV (just don't have a 360 with HDMI out yet) so if I remember correctly the pixel mapping is easier on my TV than it would be with 720p. I could be wrong but whatever.

That doesn't make any sense. A pixel is not high or standard definition. You cannot have "high definition rows" and "standard definition rows" mixed in some sort of bizarre Frankenstein signal and you certainly cannot interlace "every other" row while somehow not interlacing the other half.

How it really works:
A 720p signal consists of 720 rows of pixels that are 1280 pixels wide. 60 times a second, all of these rows are updated.
A 1080i signal consists of 1080 rows of pixels that are from 1440 to 1920 pixels wide. However, these rows are updated in alternating fashion; first the odd rows are updated over 1/60th of a second, then the odd rows are updated over 1/60th of a second. Ultimately the entire frame is updated 30 times every second.

So after saying that, what do YOU think is better?
 
For now I gotta go with 1080i. Before it was 720p for me but I recently got a 1080p set and with 1:1 Pixel Mapping enabled, the image looks very good.
 
Wow,... a lot of talking out of the old asses up there.

720p is ALWAYS going to look better than 1080i for games and movies.

The interlaced 1080 is for photos, still shots, webpages, and anything static or not moving.
When you stop your character ingame in 1080i, it will appear to look better, but when you're playing it's obvious that somethings not right.

Unless your set upscales everything into a progressive mode, you will notice the difference.

Progressive scan is a must for games, dvds, and anything else that moves faster than a normal pixel can be refreshed. If you seriously can't see ghosting, smearing, and oddities playing a game like Gears of War in 1080i, then you probably have a good set.

There is no debate,... just a placebo effect spawned from seeing 1080, knowing that it's bigger than 720.
