2407 A01 - I still see banding...

Hi,
 
Having gotten my A01 monitor 2 days ago, I decided to see how good 1080i clips would look on it. So I downloaded some from the Microsoft WMV page. To my surprise, I see quite noticeable gradient banding, especially for certain clips where there is a lot of blue sky. In this clip:
 

http://download.microsoft.com/download/6/1/c/61ca6316-a44f-46ef-9e8c-074c3dd813c0/To_The_Limit_1080.exe

The first few seconds of this clip, when the camera rotates to show the rock-climber, the sky shows quite noticeable gradient banding on my screen. Same for the other clips and other some other videos I've watched. Will those with the A02, A01 revisions with FAST connections try this out and see if you spot the same thing I did? (Its a 100+MB file) When I ran the banding test application, it was ok, not that noticeable in Desktop mode, but in the clips its really obvious.

Running on Leadtek 6600GT, 2407wfp A01, NeroShowtime & VLC Player @ 1920x1200 @ 32-bit colour.

    I think it might just be the video. I just played it on my Mitsubishi Diamond Pro 900u CRT, one of the best CRTs and CRTs are not known for banding to begin with and I also saw a bit of banding in the blue sky in that scene at the start of that video. Especially farther out towards the corners of the sky where it got brighter, could definitely see some. So I think that sample just has some banding intrinsically encoded in it for whatever reason.

    Have you at least checked the source on a monitor that is known not to have banding issues? Anyway, I didn't really notice too much banding although I have A02.

    Ah, ok.. Well I tried it on my office 17" Samsung LCD, and although I saw very faint banding, it wasn't as obvious as on my 2407.. maybe the large screen compounds the problem and makes it more obvious, I dunno. But since skibum5000 says he notices it on his CRT, then the source probably is the culprit

    I'm sorry, don't understand the question... was it directed at me?
