Currently Being ModeratedMar 29, 2010 2:15 PM (in response to jordanfel)I have exactly the same problem after the 10.6.3 update. Using a Samsung 2232BW. Had this problem when I first bought the Alu MacBook and waited 4 months for a fix. Now my monitor does not work at all. I'm limited to the my Macbook screen. Apple's quality control is appalling. I need to use the external screen for photo & movie editing.
I think I'm moving back to PCs very soon. Getting tired of the hassle of it all. At least my PC does not render pieces of hardware useless!
Come on Apple sort this out it is not good enough!!Macbook Alu 2.4 + Mac Mini Core Duo, Mac OS X (10.5.6)
Currently Being ModeratedMar 29, 2010 2:36 PM (in response to prayme)Apple if this were a first-time problem I'd treat it as I did then with an "oops" and ask you to fix it. I'm seeing no difference between back then and now. I've even reset the PRAM and restarted the computer several times with and without the external connected. I've reset the monitors and made sure that they are gathered.
Now, when I restart with the monitor attached the white startup screen shows on the external, if connected, but beyond that stage the external monitor flickers in and out. The screen, I briefly see, fits to what should be there but becomes black. There is no difference between what I saw back the first time this happened and now. Why?MacBook Pro, Mac OS X (10.6.2)
Currently Being ModeratedMar 29, 2010 7:37 PM (in response to jordanfel)Same problem! I cannot get full resolution to work. Works with a lower resolution though, but that screws up my screen layout.

That's not a long term fix, just a data point that will help debug the issue.Quad 2.5 GHz G5, 5 GB | 15" 2.6 GHz MBP Penryn, 4 GB | 1 TB Dual-Band TC, Mac OS X (10.6.2)

Currently Being ModeratedMar 30, 2010 8:59 AM (in response to satcomer)I'm having the same exact problem with a unibody macbook (not pro model) and a samsung 20" 206BW external monitor hooked using VGA adapter.
One weird thing is that I've a double entry in the menubar monitor resolution list for the maximum resolution (1600*1050@60Hz). One of them gives a normal display, the other shows the same symptoms.
In clamshell mode, that I can no longer use with 10.6.3, there's no way to force the right setting, which I could do before, although not a fail safe process.
Will this be fixed at some point ??
Although, is there any chance that switching to DVI connection would solve the problem ?Macbook Unibody, Mac OS X (10.6.2)
Currently Being ModeratedMar 30, 2010 9:47 AM (in response to jordanfel)am having the same problem too..
Samsung 225MD. Worked fine until 10.6.3 update and now it flickers. Was running at 1680 x 1050 at 60Hz and now i have to run it at 1600 x 1500 at 60Hz to see the screen but its blurry
But reading other posts it seems to be mainly issues with samsung monitors...=SMac Mini & MacBook Pro, Mac OS X (10.6.3)
Currently Being ModeratedMar 30, 2010 10:18 AM (in response to satcomer)Thanks for the reply satcomer. Certainly my issue is not related to the recall. I have the first gen Macbook Aluminium not Pro. Also my issues are not the same.
This issue was resolved with an update around a year ago after many people were experiencing the same issue. Currently unless I am mistaken the reoccurring problem is affecting Samsung monitors only.Macbook Alu 2.4 + Mac Mini Core Duo, Mac OS X (10.6.3)

Currently Being ModeratedMar 30, 2010 11:59 AM (in response to d_raux)I have the same flicker problem since I went on Snow Leopard. Having Macbook unibody (not pro) + VGA + Hyundaï W220D. Before 10.6.3 I use to solve the problem by checking/unchecking video mirroring in the monitor preferences and the flickers stopped (And I had to do this EVERYTIME I turn on my laptop). But since the last update it does not work anymore. The only way I can get a fix image on the external screen is to use video mirroring all the time. But I'm stuck with the 1440x900 resolution on a 22"... My external screen is just unusable.MacBook UniBody (Oct 2008), Mac OS X (10.6.3)
Currently Being ModeratedMar 30, 2010 3:14 PM (in response to jordanfel)Have any of you made sure that your external monitor and LCD were set to the correct resolutions? I'm now not certain that I'm certain of that. If any of you are certain, that bombs out my feeble hope to correct the problem.MacBook Pro, Mac OS X (10.6.2), I'm back to 10.6.2
Currently Being ModeratedMar 30, 2010 9:46 PM (in response to jordanfel)The issue here is with a Dell 24" monitor. All OSX updates up to 10.6.2 had no issues. 10.6.3 now produces green pixel artefacts and flickers on the external monitor. If I drop the resolution to 1024 x 768, there are no flickers. Most recent MBP being used to drive the external display. Looks really bad and makes photo editing in Aperture useless. Need a fix Apple.MBP 4GB RAM, External Dell 24" Display
Currently Being ModeratedMar 31, 2010 12:22 AM (in response to jordanfel)Hello all,
Just to say i got the same problem as many users. Before the update 10.6.3 everything was ok but now I symply can't work with my highest resolution ( to know : 1680*1050 ). I have to work in 1600*1000 and that very weak...
I tried to reboot with or without the mini display port VGA pluged, delete monitors preferences, launched a full onyx clean, create a new user, reset the ram but nothing worked till now !
I got a macbook unibody ( 2008 ) and i use a Samsung T220 with a minidisplay VGA.
If anyone got a solution, please tell because im loosing my nerves on that...
Thanks.MacBook Unibody 2008, Mac OS X (10.6.3)
