MacBook Pro 17'' Early 2011 Screen Strange Horizontal lines in some colors

Question

Hello guys,
I've just got my new Flagrant MacBook Pro 17'' Sandy Bridge i7 2.3Ghz 8GB SSD512 with Glossy screen and is amazing.... But...
I am incredibly disappointed with the quality of the screen (or maybe the videocard?) I come from the previous generation MacBook Pro i7 15inches and the quality of the screen was superb. Now on this new 17'' screen I see some wired horizontal (very tiny) lines in bright colors (very difficult to notice by an untrained, not to hock to perfection eye). This was actually the first thing I saw when booting my mac for the first time as the gray apple appeared not to have a perfect gray color. First thing I did was going to an Apple Retail store we have here in Barcelona (Catalonia) and strangely the MacBook that was in there had a very similar issue. Is not something you can easily notice, but if you look close to the screen you can see this lines. I am not really an expert, so I don't know if this could be a problem of the videocard (does ATI cards have less image quality than nVIdia?) or is a reduction of quality of the 17'' screen compared to the 15''?
I am very annoyed by this, and I am considering to return my laptop as I'm really not getting used to it. Does anybody know if this affects all new MacBook Pro's 17''?
I'll try to get a camera with a macro to upload a picture and give you an example.
Thank you guys.

This guys is having EXACTLY the same problem that I detected:

And his explanation is quite clear 
(copied from this post)
Description: Every other horizontal pixel row appears brighter than the alternate, creating a scan-line style effect that also contributes to the washing out of the display. In seemingly random "luck of the draw" machines, lines can either be highly visible or not be present at all.
In displays where it is faint, you may not notice, but once you become aware of it is a real problem if you work closely with your computer, and graphics.
This appears to be the same issue that has been widely reported in the past with Macbook Air computers.
The three computers that I have had this issue with:
1 - Glossy, 9C99, lines visible even from three feet away.
2 - Glossy, 9C99, lines about half the visibility
3 - Matte, 9CAC, lines again about half the visibility of #1
I have also had 3 glossies and 1 matte that have not had these lines at all. 3 Unibody 15" MBPs have also not had any such lines. I have also been unable to detect these lines on any non-Apple computers I have observed, nor any of Apple's other models or displays.
I put a 17" Matte without the lines next to one with the lines and attempting to take photos, but could not get them to turn out at all for a variety of annoying reasons (unclear image, moire effects, etc). I was however able to take extremely close macro shots and there is a difference visible in the pixel arrangements, apparently.
Who else has this one their display?
Thanks
