1080i Vs1080p

[Osmo]

So I was playing around with my new t.v and xbox 360, viewing it in both 1080p and 1080i. And there were big differences.

1080p - Everything looked duller and darker, Pro Evo2010 - the game I tested it with, had a generally darker theme to it all. However there was motion blur still, but it was reduced significally, making the movement of the players and ball much less blurred.

1080i - Now when it came to contrast and colours from the xbox dashboard to the game pro evo 2010, it looked much more alive and more beautiful and just livelier, with a tinge of being slighlty over contrasted. The black shadows in the letters and players looked much better, and things just stuck out. In a still image the detail was there and it looked really good. However in a there was like a greater amount of pixelation and motion blur when players were moving fast, kinda made it look tv tube ps2, and the edges of general graphics were ...less rendered? they just looked more edgy.

1080i uses half the bandwidth of 1080p. Thats probably why. They can fit more data about the actual picture since it only renders every other line.

Is pro evo soccer a 1080p game? most xbox games are 1080i or 720p they are just upscaling them to 1080p. Same with the dashboard. Its not a native 1080p. just upscaled.

So what are you saying? that the games will lose quality when it's upscaled to 1080i? or that a 1080i/720p game will look better on a 1080i resolution?

1080i --> 1080p : De-interlace
720p  --> 1080p : Upscale

I really don't understand what that means

i know that 1080i doesnt show a complete new frame every second and that progessive does

When interlaced only half the lines are drawn at a time. It halves the amount of data required. If you fix the data rate, then there will be more bandwidth availible for colors. This results in the better coloring you mentioned in your original post.

Okay so if I'm right about the colours (i can clearly see that right now) then why is everyone banging on about progessive scan? is there like a pro that is reduces blur (i doubles checked and the blur reducation isn't much) and the con that the colours are more bland making it look more lifeless?

I believe the increase in overall visual quality with 1080i over 1080p in your case, is solely due to specific hardware and system limitations.
To produce a full frame each refresh (progressive [1080p]), is understandably more work than to produce, what sums up to be half a frame per refresh (interlaced [1080i]. So with 1080i there is a greater potential for extra effects than with 1080p.

In other words, the game developers may have decided to lower the quality of certain rendering settings when the game is forced to run on 1080p, in an attempt to maintain system stability and smooth performance. The same way one may have to lower shadow quality on a pc game, when trying to run it at a high resolution. Again, here it will depend on you system and the software.

Note: This is more of a simple way I would explain this to myself. I do not own a xbox 360 or any gaming console (I'm an pc-gamer ). This explanation just seems logical to me.

it makes sense, but what your saying is, xbox 360 can't handle 1080p right? because it's not only the game quality it's the xbox dashboard (xbox menu)

[Rebs]

Well, I do not really know about whether or not it can handle 1080p. I have heard it cannot, but this could again depend on what you are trying to render at 1080p.

But anyways, I do not know this stuff and will not speculate any further. I will however say this: not every thing needs to be rendered at 1080p. Sometimes it's just unnecessary...

The xbox dash native resolution is 720p or 1080i I cant remember off the top of my head. same as most games. What happens is they usually double each pixel displayed twice in a row to match your 1080p output. Now what these means is A if you have a good up scaler doing the work it turns out fine. Hence why some people still buy $300+ dvd players. Now if you have a crappy up scaler the results are a crappy picture. The xbox360 does this in different ways that use an internal buffer. for some games. Project Gotham is one of them that uses internal buffer and the output is 1024x600. Last I checked there was only really like 10 true 1080p games for xbox360. The lowest a game can be is 720p/ So keep the resolution set to 720p or 1080i. For the best picture from the xbox. You always want to try to match the native resolution of everything in the chain. just putting it to 1080p does not always result in a better picture.

What kind of cable are you using? Are you using an HDMI cable or the Component cable?

If you're using Component try switching to HDMI and see if that makes a difference.

What exactly are those games?

Native meaning original resolution of the game, t.v, dvd, console is?

Native meaning whatever the content is you are trying to play.  here is a list of native 1080p games for the 360 i dont know if they keep it updated anymore. http://www.makeyougohmm.com/xbox360-1080p-games/
So keeping your xbox at 720/1080i is your best bet.

If your content is all in the 720/1080i range you do not gain anything on a cheap up scale. to go to a 1080p.

[fohfoh]

If you're trying to test 1080p, make sure you're using something that is 1080p.

I remember a while back some morons running around going, ZOMFG! N64 LOOKS TERRIBLE ON A 50" TV!

[sdedalus83]

A modern LCD TV is going to have to convert a 1080i signal to 1080p while it can display 1080p as is.

You're just seeing the effects of the TV's internal deinterlacing, scaling, and image processing.

With the 360 the output resolution of the console is not necessarily the same as the resolution at which the image is rendered.  The system scales the rendered image(often the same no matter what the display resolution is) to whatever display setting you choose, and then the image is transmitted to the TV.  Use whatever is the native resolution of your display for the best image quality.  Use whatever you like to suit your preference.
