1080i vs 720p

[Shadow Conception]

So anyway, I notice that 1080i looks a lot sharper on the XMB than 720p. My TV is 720p/1080i only (native res is 1360x768). And I don't really notice any flickering with 1080i.

But is 1080i supposed to be sharper? I mean, it's a lot sharper and nicer looking in the XMB. In games like GTA4, it's completely unnoticeable (as it's supposed to be).

atm I have it set on 720p for smoother gameplay. Fact is I can't tell a difference between the two in gaming, and I doubt anyone else can either.

So the question: is 1080i supposed to be sharper than 720p? It's more pixels... but it's also interlaced and also downscaled by the TV to fit the 1360x768 native res.

First, what is the "XMB" ?

Second, use 720p.

XMB = Cross Media Bar or something like that, the GUI used for the PS3, PSP and some other Sony devices.

I'm not sure it matters if you can't tell the difference. However, 1080i seemed to die off pretty quickly... makes a lot more sense to just go with 720p for "low end" and 1080p for "high end."

1080i is supposed to refresh so fast that you don't notice it so it will provide more data than 720p. Not everyone's eyes are created equal though and some do notice flickering. If you don't 1080i will be sharper. Go with what looks better to you, don't worry too much about what is supposed to be technically better.

You have a 720p TV. If 1080i looks sharper, its due to processing being done by your TV, and youre probably going to experience input lag. Stick with 720p and turn up the sharpness.

Even if you have 1080i enabled, most games will stick with 720p anyway. It will stick to the native resolution and only upscale if 720p isn't chosen.

i leave mine on 1080i. Call of Duty 4 and the XMB look much sharper on 1080i than 720p......but that's just me

LCD TVs are fixed pixel progressive displays, regardless of source, you are seeing progressive output on the screen. How well a particular LCD TV does de-interlacing and scaling, is a another story. I doubt the PS3 is doing anything to affect it before it reaches the set. Sony even uses the XMB in some of their TVs, so I can't see how there would be any issues, like happened early on in its life cycle *before a firmware fix*, when games that defaulted to 720p would scale down to 480p on TVs that didn't support 720p.

i use 1080i over 720p on my 26 inch sony that is about 4 feet from my face.

I've got my Xbox 360 Elite hooked up to a 56" DLP via HDMI and I leave it on 1080i with no issues. On a recommendation here, I tried 720p for a week. Other than the obvious drop off in resolution, I noticed no discernible difference, so I switched back.

Here's looking forward to the next console generation's games that will start having native resolutions of > 720p.
