Socom Question

[sega4life]

Opening info:

Just got Socom and the Official Headset Combo for $39.99 at Circit City Closing Sale...

________

Problem:

Now the back of the box says it supports 720p, 1080i, and 1080p...

But when I play the game it stays in 720p?

I went into PS3 setting and I have 720p and 1080p selected under display..

I have a 61" 1080p TV..

What do I do to get the game in 1080p?

 

Thanks in advance
