    So I know many people have either the low backlighting flickering issue or has the once in a while flickering (whole screen flashing black in a split second) issue and wanted to know if it has addressed their screen issues.

    doesnt help my low brightness screen pulsating/strobing. Not sure if it helps the split second blink . I rarely got those anyways, haven't seen that in a while.

    10.5.7 didn't fix the flickering when scrolling fast through long lists or websites on my unibody MBP 2,4 GHz. Although it's not really a problem for me i still wonder if it will be fixed at all.

    Man I've never seen so many problems in the mbp especially in the 17" mbp (which in the past usually have no issues).

    I really really really really really want a 17" unibody mbp but damn!!

    I get the pulsating when on the 3 lowest brightness levels ONLY when I am at 40% battery power or below.

    No improvement on the "black flash/redraw bar/screen" problem (not backlight flicker). The firmware update did help - I only have to switch to the 9400, then back to the 9600.

    It's still infrequent, and only happens on wake from sleep. Otherwise, no artifacts whatsoever (X-Plane runs fine, for instance).

    I'm still convinced it's a software issue and since everything else is perfect on this machine, I'll wait and see. I still have a ways to go on warranty (might even spring for AppleCare).

    Bummer

    I was just about to buy a MBP 15" until I started hearing of these screen issues. Fact that one bought as recently as May 14th has issue still occurring is very concerning. I refuse to play stupid games with exchanges, returns, and fixes to correct problems like this. I simply won't fall into that trap. So, Apple inc, for now, NO SALE. Get your problems fixed!

    hmmm..just noticed this as well (may version). I'll hold off on any repairs just yet until updates or maybe SL. But if it gets worse then i'll have to give in to the repairs.

    Yep! But I read something earlier that explained the cause of the pulsating. It's due to LED's inability to be dimmed which they overcome by causing it to pulse at a different frequencies (slower if dimmer, faster if brighter) and so some unlucky people do notice these pulses but the majority don't, sometimes the eyes do and sometimes the eyes don't. My eyes are extremely sensitive, I use to notice flickering of CRT TV's as well as fluorescent lights, when no one else could. I have to also mention that having it on battery power affects the pulses, they seem to get slower and therefore more noticeable. I think this is caused by low voltage from battery or something to that effect. If it gets worse and unbearable you should take it back as it's a risk and may actually be defective.

    is not a software issue is an hardware issue
    if you try another os ( I tested with ubuntu) that is able only to use 9600 the flickering is present
    I hope apple deliver a firmware upgrade for the 9600 but over 8 month has been passed from the release of this Macbookpro and nothing has been fixed, even the really bad performance of the 9400 :( I'm sad

    If you are talking about the Mini Displayport to Dual Link DVI issue, then it is a BIG YES!!!! :mad::mad::mad:

    Imagine having this problem from a $100 cable, needed to drive a $1300 monitor by a $2800 Laptop....

    Pathetic...

    there are 2 issues in regards to flicker:

    1) mild strobing/pulsating slight dimming in and out very quickly more noticeable at low brightness levels and solid white/grey backgrounds

    2) the one where the screen 'blinks/flashes' for a split second on and off very quickly.

    Mine is number 1. I've had number 2 on occasion but very rare and that doesn't bother me.

    Same :(
    Though luckily mine only does it in Safari, but it was distracting enough to make me switch to Firefox until theres a (hopeful) fix.
    I've only ever had the pulsating screen happen in Boot Camp (running Windows 7), and only periodically - it only does it when I'm pushing the processor and GPU to the limits (for example, for several minutes after coming out of a highest-settings-only session of Oblivion).

    mine does it on 9400 when computer is cold from startup, goes away after 10 minutes. But the 9600 is more constant, especially when computer is hot.
