Hi all,

I bought a unibody macbook pro shortly after their release. I've noticed lately that with prolonged usage I get some pretty weird eye strain that kind of reminded me of whenever i would use friends' CRTs that didn't have pleasing refresh rates. Then I saw this :

http://livescore.com/

Sites like this/ones with similar backgrounds give off a constant flicker without even scrolling the page. What I am seeing resembles low refresh rate pulsing or something like that; I believe I'm even noticing the flashing now slighty if the screen is a very bright white.


Could anyone with a Uni-MBP take a look at that and verify if they see the same sort of "problem"?

Result the same on either gfx card setting in Energy Saver.

Thanks!

Do you think it is normal though? I've had it happen on all sorts of other sites as well; pretty much anything featuring scan lines like that...

I had an Asus laptop that would have flickered on a page like that (as it did with other similar graphics). My current HP is fine.

It depends on which LCD you have. When I had my Macbook Alu. (regular), both AU Optronics screens I had were awesome and had no flicker. When I got one with the LG screen, it flickered on lower brightness settings and ssome backgrounds. Might not be annoying for some but it annoyed the hell out of me just knowing it was there. More proof that Apple does not equal quality.

Yeah. I think I might drive to the store this weekend to see if they'll exchange it or something while I am under warranty. It really bugs me, hahah

Don't have a MBP, but:

I have a Dell with a AUO3214 screen. It flickers while scrolling. Not that it annoys me much though.

It's not normal. I browsed the site on my 22" Samsung driven by an 8600GT and I get no flicker or moire patterns at all. Just the striped background.

Its common in TN screens, which all notebooks have. Don't worry about it.

LCD test

LCDs aren't perfect, and most of them will have problems like the one you described that are only noticable in rare situations (even high-end ones with IPS or PVA panels).

Its flickering slightly for me as well. I am on a old gen MacBook Pro. I wouldn't worry about it. Plus, I think you'd be hard pressed to find a screen that didn't flicker even if you got it exchanged.
