Xbox 360 at 1080i help!

[yancy01]

Hello I have a Toshiba 26HF85 and when I play call of duty 2 and perfect dark zero there is a problem. When I look around and move there is a werid blackness or some type flickering when I move realy quick but when I change the xbox to 720p there is no problem. Please I need help!

[spottedfool]

ok..well if your TV accepts 720p...and there is no problem playing at 720P...what exactly is the problem?

[AdminJoe]

is the video cable set for hdtv?

Sounds like a common disadvantage of interlacing (1080i). At 1080i the xbox 360 does 30fps interlaced, while 720p will be 60fps and progressive. So depending on the TV and situation, 1080 will either look amazing or crap.

Try playing the game in a dark room. If that doesn't help, play 720p; it's still amazing even though you have twice as less pixels. But in 720p you get two big advantages: Progressive and 60fps.

Wrong, it's 30 frames and 60 frames... Not Frames per second... If you go by what you say then playing on a PC using interlaced display modes would only get 30fps which means I must be god and can get 80fps playing BF2...

[provoko]

Uh... ok, haha, 30 frames what? These frames just.. happen.. at no particular rate?

I think you're confusing how many frames a graphics card can produce and how many times that image is displayed on your TV or computer.

In 720p, on a TV, the image will be displayed at a rate of 60 frames per second; in 1080i it's 30 frames per second. If you didn't know this, now you know. (http://www.hardwaresecrets.com/article/123)

You also confused interlacing with 30fps. Interlacing will just look bad in certain situations to begin with, thats why I said interlacing has it's disadvantages.

There are ways to post information that do not slag another individual. Please all try to post in that manner.

or do you mean 60HZ?

Since that's 1080i refresh rate similar to a computer monitor.

Also your wrong Interlacing is'nt bad, it's actually good for still images, the only time Progressive is better is when there is fast movement on screen.But even then it's hard to tell the difference from 1080i and 720p, to me they look the same, albeit 1080i having the edge in overall clarity.I have noticed nothing of what you speak of, they are virtually the same, just that 1080i is a bit crisper overall.

I don't see the issue, they are both good, just use what ever your tv's native display is.

I haven't given one example... Haha. Why are people making assumptions of what I orginally posted? I'm only laying down the facts.

Here, base all further criticism on this example:
A fast moving object in 1080i (or any interlaced source) may leave trails or tearing.

I have nothing against either resolutions, but from what yancy01 stated in his topic:

When I look around and move there is a werid blackness or some type flickering when I move realy quick but when I change the xbox to 720p there is no problem. Please I need help!

The answer to why thats happening is because of interlacing causing tearing/flickering. The solution, if anyone has been following, is to put the game into 720p because it's progressive which will prevent any tearing.

This is not a discussion or argument to what is better or not, the topic starter asked for help, I laid down the facts (you can't argue facts) and I've given a solution.

If anyone has a better solution, please post it.

I have this same tv and mine goes wonkey in 1080i as well, exept in a different way. My set gets brighter at the top of the screen in 1080 and is uniform in 720p, however what gets me is that the toshiba in question does not actually support 720p, it upscales to 1080. I just play in 720p even though it just scales the image up to 1080i, I have gone back and forth and cannot see any difference in picture quality except for the uniform brightness when set to 720p. So maybe this tv just has some issues, or the scaler in the 360 is not to great. I'd just leave it set to 720 the scaler in the tv seems to work well.

[57U]

If the original format of the game is 720P and your TV will accept a 720P signal, I'd output the Box at 720P because the TV is very likely to be better at converting any formats than the box.

The native resolution of the TV in the first post is 1080i.

Thank you all for your help. All this info is starting to make sense.

I also have a 26HF85C (I think the C is for Canadian). When using
the Xbox 360 in 1080i there is color distortion even on the Xbox dashboard.
Also PGR3 looks absolutley horrible. All we need is a few people to concur
this problem and we can go to Toshiba and ask how they propose to fix it ;).

What does everyone think?


To make things clear:

The 26HF85 has natural scan rates of; 1080i, 480p, 480i, 720p.
The option where you can select 540p/1080i, only applies to 480i or 480p
signals. It will upgrade these signals to 540p or 1080i according to your
selection.

(480i/p is not true HD, therefore Toshiba converts it to HD)

[Klesk]

You get well over 30 fps in any hd mode on the 360.

Oh and, I have the same tv, it looks best in 1080i for call of duty, pgr3, and pdz. 720p, for me, flickers alot and more jaggies, so 1080i is better for me, but as ive learned every tv is diffrent.

Hi there. Maybe the solution here is to go back to what it says on the 360 site about High Def. 720 p was picked for the games to be built in to avoid the very problem that Yancy describes. For fast action games 720p does a better job that 1080i. Robin

[mgonzo2u]

Short and sweet.

Nice post with a relevant solution.

[Failsaved]

I have a Toshiba 26HF15, and I have the 1080i flickering issues as well. In turn I switched over to 720p, which looks great exept for the fact that an inch of the left side of the screen is cut off. Is there any way to adjust that?
