my white 13.3 inch macbook has developed like a flickering problem, its a good few years old, max memory on this one is only 2gb's. well anyways, the screen, it has only done it intermittently but when opening it for wake up, or when the screen dims, it ocassionaly does like a flicker thing, but only for a few seconds, then it stops. my guess, its the screen invertor.

i was working on my thesis in a completely dark room and realized that the screen on my macbook pro flickers even if the background is completely white. this annoyed me to no end since i have sensitive eyes, so i set out looking for a temporary fix before i try and get apple to replace my panel. anyhow, luck has it that there is a fix out there that at least temporarily stops the flicker (i havent seen it posted on nbr before, and my apologies if this is old news): press ctrl-shift-eject to reset the screen. once it goes blank, hit any key and your display should be good to go. worked for me and my screen has been flicker-free for ~30 minutes.

You are correct. Here is that thread.
At this point we are looking for common factors. Post up any other useful information you can think of.
Does anyone know the Hz of the backlights?
Does this flicker still happen on an external monitor?
Human vision factors:
Most people can see flicker at about 80 hz. This is most noticeable in bright light and in the peripheral vision areas. Most people adjust to the flicker rate of their local power so that they no longer notice the flicker.
Most people can see an animation as continuous movement at about 20 Hz. The brain tends to understand that it is seeing an animation and assembles it as movement. On things that are not moving, the flicker is more noticeable as your brain has nothing it can assemble the flicker into.
Some people have said that they can see the flicker while other people around them can't. This could be because some people are less sensitive to noticing flicker. This could also be because the other person is looking at the screen from farther away (say, over the shoulder of the owner) and the screen is centered in their vision, not in the peripheral vision areas. If you are one of these people please let us know it your test persons have actually sat directly in front of the laptop, just like you normally would be when you see the flicker.
I suspect the flicker is actually due to the Hz of the backlights, not the actual refresh rate of the screen.
On my Acer 5920, the screen flickers off and on when I plug up to my projector to give a power point presentation. I have called Acer NO-HELP; they said it was a 3rd party software issue, which was not true, because there is no software- it is plug and play. I called Epson; they suggested to chage the refresh rate to 60 and I did to no avail.
There final word was that it must be the Graphics Card.
I found a couple other reviews where people said they had a noticeable (more so on dimmer settings, for me) screen flicker with their timelines. I have the 1410 with su2300 proc. Anyone else noticing this problem? It's enough to distract me, which can be annoying, but I'm a bit of a perfectionist when it comes to the visuals.

View 10 Replies View RelatedI've been plagued with this problem for the past month and a half at least, so much so that the laptop has spent the last 3 weeks with Acer and their technical support team in Plymouth (I only got it back last week).
The laptop was sent off with a fault to the screen. It intermittently flickers, mainly when the screen is moved, but sometimes not. The laptop was sent off to Acer 3-4 weeks ago and was returned last week. A report was returned with the laptop and reads as follows:
Problem Description:
SYSTEM FUNCTION - SYSTEM FAIL TO FLASH BIOS
Repair Description:
STORAGE - OPTICAL DEVICE WILL NOT READ/WRITE
Diagnosis/Repair Details:
fitted new ODD and middle cover
Spare Part(s) Replaced:
ODD HLDS SUPERMULTI DRIVE 12.7
COVER.MIDDLE.W/MMN/EKEY-BD
As you can imagine, this report left me completely perplexed but I assumed that somewhere within that they had fixed the screen problem and left me with a fully functional laptop again. And of course I'd been without it for 3 weeks and just wanted to turn it on again!! lol (On a sidenote, I had asked them to check the disk drive also, because back when I first got it, it struggled to read any type of disk. This explains the apparent replacement disk drive)................
screen flicker when I turn my brightness to the lowest level, its a little but I didn't pay this much for something that could be broken,
View 7 Replies View RelatedI just received this machine, and so far so good.
There is some screen behavior that has me a bit confused though and I'm hoping someone here might have thoughts or advice about it.
Every now and again, the screen gets just a bit dimmer for just a very brief moment, not much, just a bit, and pretty quickly, and then comes back to normal. It almost looks like it wants to go into it's "power saving" mode or something, for a moment, and then back out .....
I have an Acer Aspire and it's been good to me mostly; however, I have an issue that I was wondering if anyone could help me with. My screen will flicker occasionally and it has only gotten worse. Sometimes changing the angle of the screen stops it, other times plugging it in stops it but sometimes neither work.
View 10 Replies View RelatedWhat is happening with the laptop, sometimes I noticed my laptop screen will flicker(or a bright flash as if someone was taking a picture). When I go to the event viewer it tells me Desktop windows service manager has been disabled by the windows system assessment tool. I'I have the nvidia graphics card + Intel(using optimus technology),running windows 7 professional 64 bit.
I forgot to mention when playing videos I think the graphic card makes a strange noise like there isn't enough power or something (Not 100% sure)
I have nvidia gt555 with intel Optimus
Intel 2670m
8GB of RAM
Windows 7 professional
I tried to do a fresh install of windows 7 but the problem still persists and I cannot test it since I have deleted the recovery Drive. How do I test if the graphics card is working properly
I use the latest Energy Management and the latest graphics driver, as well as the latest BIOS version, but the flickering issue persists.
View 9 Replies View RelatedI didn't upgrade my BIOS, it came with the latest BIOS because of the graphics card. The people that have fixed it by downgrading have a older version of the same laptop with a different graphics card.
View 2 Replies View RelatedMy x120e has been giving me grief recently. It started when, upon awaking the computer, my screen would be very distorted. It was mostly horizontal and was different from the known horizontal screen flicker issue. It would take up large parts of the screen, but no more than half. Now get this, the distortion changed totally depending on what was on the screen. I could even get it to go away completely if I just opened the start menu (with my task bar on the left side of the screen). Typically a restart would alleviate the issue.
I would get a screencap for you guys, but last night I shut down the laptop to 'fix' the issue and the screen never came back on. I can still use an external monitor so I'm not thinking this is a graphics card problem, or at least not entirely.
I don't think this is the same screen flicker that is experienced by the few others due to auto brightness problems...
It's flickering black and then the whole thing turns unresponsive after a while...and although the video shows it happening during a low light environment, i have had this encounter during a brightly lit area as well...

I'd like to get one of the new pros, either a 15" or 13". i don't need the 9600gt as I just web surf and do documents.
So its either
the 2.26 13" version
2.53 13" version
or 2.53 15" version.
What I'd like to know is which screen has more pixels per inch, ie a clearer/crisper screen.
I'm used to a full hd vaio screen, so which would be the smallest step down in terms of crispness of images?
I recently purchased the 15" macbook pro from apple online store. I immediately noticed that the screen was a lot less vivid/washed out than what I have seen from demo units at the store.
I did not find many similar complaints about the washed out screen so I was wondering if this is an isolated incident.
I have returned the unit and was thinking whether I should give it another shot (buying it in the store).

I've got the 9C84 which is the LG/Philips LP154WP3-TLA1 as far as Google says.
You can check your display manufacturer in System Preferences click Displays, go to Color tab and "Open Profile". In this list scroll down to number 17 which is "Apple display make and model information".
This is what Google says:
9C84 = LG/Philips LP154WP3-TLA1 (15" MacBook Pro)
9C85 = Chi Mei N154C6-L04 (15" MacBook Pro)
9C89 = LG/Philips LP133WX2 (MacBook UniBody)
Don't know about the Air, sorry.
There are quite a few people sharing their calibrations on Macrumors and other forums, I've tried some of them and frankly, they're either too blue or too bright...........
I have a question about the screen that is use on the Macbook Pro 13". Does the Macbook Pro 13" have IPS screen.
