I'm using an external monitor (acer p235h) hooked up to my mini display port w/ an hdmi adapter. Before I updated I had no problems but when I updated to 10.5.8 it seems that I have some "flickering" issue. I'm not sure if it has something to do with the refresh rate but basically it looks like my monitor is slightly vibrating. Does anyone know how to fix this?
View 1 RepliesSo, I replace my MacBook Air Rev. A for a Rev. C (2.13, 128 SSD). I'm more than happy with the performance increase, not so with the graphics.
I got the lines. They do not bother me, as you can hardly seen them. However, I use the MacBook at the office, hooked to a 17" VGA monitor (Viewsonic 1280x1024, 75 Hz) with the Apple VGA-MiniDisplayPort adapter. I never had any problems with my old Macbook Air, but now I'm seeing flickering and I think the display is not as sharp as before.
If I use the computer in clam shell, only with the external, the flickering goes away. Also, I haven't detected any flickering if I boot in Windows 7 (although I haven't used it much).

I'm using an external Monitor (Compaq W185q) and everything's ok until I open certain webs, this websites have banners on both sides mostly, so I think that's important to tell. After couple seconds on those sites, the monitor starts flickering and then it turns black, completely. To make it work, I launch Mission Control and it starts working again, I drag the safari window back to my MBA's monitor, and problem solved.

I am trying to connect my Macbook Pro (bought Fall 2009) to a external monitor - an Asus VW222. I use a VGA converter which I bought together with the mac, I plug a VGA cable in the converter and then I plug it into the display port of the mac.
I do get an image on the Asus monitor, but it is not very useful. It is flickering between a yellowish color everywhere and normal colors. Moreover I cannot change the resolution. If I set the resolution to 1680*1050 (the Asus' native res) then the image still looks scaled/grainy and it doesn't fit on the monitor. The top menu for example is outside of the screen and the whole image is slightly moved to the right so I have a black bar to the left. If I set the resolution to the mac screens native res, 1440*900, the image fits on the Asus but is of course scaled. I tried go to system preferences and calibrate, but it did not help.
Recently I connected my macbook air (bought it in 2011, now on Version 10.9.3) with a Panasonic TV (TX-32LM70F) via Thunderbolt to HDMI adapter. After I disconnected the external device, the macbook air's screen still worked normal, but when i restarted it, it was only flickering grey.
I found out that it actually boots normally and i can use it with an external monitor (in fact I am using it right now), but that the built-in macbook screen simply doesn't work anymore.
I tried to restart while connected and while disconnected to an external screen, I have reset the SMC Controller, I have reset the PRAM Controller, but it hasn't changed.
This is actually the second time something like this happenend (it was another external device i connected it to), and last time, about a few weeks ago, it just worked again after a few days for no reason, all i did was wait until all energy was gone from the battery and the reload it. So might it be a battery problem? Or is it some controller i don't know? It was the same phenomenon two times: connect to external monitor - disconnect - built-in screen still works - restart - built in screen only flickers grey - macbook still boots and works fine with the very external monitor that might have caused the problem.

Thing is I got hold of a 1ghz 17" iMac almost for free, it had a dead logicboard (I checked it with a voltage-meter), but I figured I could fix it and have a small hobby project-thingie going on. Well I just got a new logic board today, for a 1ghz 17" iMac g4.
Things is I only get a bright grey screen from my Mac when I boot. I've tried connecting it to a external display and that works fine. Everything is there.
I then reinstalled Tiger on it, with the computer connected to my external screen. And I still have the same problem. (I have now disconnected the ext. screen and is controlling the iMac from my MBP). So at least it isn't the installation.
So what is the problem? I can via an Apple Keyboard control the brightness on the blank screen, which would indicate that it does react to input of some degree.
I've read that if the inverter is dead or anything else is dead, you would get a rolling grey screen, flicker or something like that and not a steady bright grey. One thing I'm thinking is. What if somehow this logic board was for a 15" 1ghz imac g4? Can I check this?
I read that long thread about guys buying hi-res displays for their MBPs, and they had to replace some display profile? Could I maybe fix it with a different display profile-file?
I'm really confused by all this, and would appreciate any help I can get.

Since I updated Snow Leopard to Version 10.6.8 on my MBP15, I can't use my SyncMaster P2770 HD (Samsung) in its highest 1920x1080 resolution anymore. I can choose 1920x1080 in the monitor-preferences, but having done that the resolution remains at 1680x1050 @60Hz (I can see it and even the monitor's info-menu says, that i still use 1680x1050 @60Hz). I use a Mini DisplayPort to VGA-Adapter and a VGA-cable.

Does your screen flicker too, when you watch this pattern ?

My white Macbook, the one i'm currently typing on; the screen keeps flickering. 've uploaded a video taken from my cell phone of the screen flickering. I love my white macbook but the screen keeps flickering until I keep adjusting the angle of the screen. Some days the screen flickering is minimal and I'll adjust the screen easily with minimal screen flickering. Other days i'll be adjusting for a few minutes until I can get it at an angle where the screen doesn't flicker.Here is the link of the screen flickering: [URL]I've noticed there is less/to no flickering at all the closer I adjust the screen downward, i.e., the closer it is towards the macbook itself being closed.
As for the Macbook itself, it was purchased in December 2006 and have had AppleCare since. In June of 2007 I took it in to Apple since I noticed the screen flickering very minimally only when the screensaver came on. I was then told a small soda spill was on the logic board and AppleCare would not cover it, though I was still covered regarding all cosmetic repairs, aside from that soda spill. It hasn't been till the past 2 months the screen flickers heavily and I'm just sitting at my desk adjusting the screen until there is no flickering so I can get my work started. I was considering selling my Macbook for anyone that wouldn't mind the screen flickering but i've upgraded this Macbook with a 500 GB hard drive and before attempting to sell it i'd rather fix the problem myself.
Everyone, I'm all ears. I'd love to fix this problem. If it means completely voiding my AppleCare warranty and opening up my Macbook, so be it. the warranty expires in 6 months anyway.
I did a quick search of the forums, and so I know there are previous threads about this. But my screen is flickering a lot lately and so I plan on either sending it to Apple, Driving 3 hours to Dallas since it's the closest Apple store, or taking it to an authorized repair place here in town. I just have a few questions for anyone that has either had this problem before or maybe just has dealt with repair issues before.1. Should I wipe my Hdd?2. Which of the three options would be the better bet?3. Anyone know if they would just fix it or if they would replace it?

View 2 Replies View RelatedApologies if this has been posted before, but rather than trawling through the thousands of threads, and before hitting the Genius Bar.... thought I would run this by the experienced MBP owners first.Got my first MBP (crossed over from PC back in April), and within the last couple of weeks, noticed that the screen is flickering intermittently.
Wondered if it's a glitch stemming from the switch from Graphics card as/when needed, or if it's an indication of something more serious and warrants taking it in to the Genius Bar... (don't want to part with it for days unnecessarily).
I went on a website only to noticed the black lines & columns on the page, especially at the bottom, gives off a noticeable flicker on my 13'' MBA.
Obviously with the issues of MBA screens, I'd like to check with you if the same thing occurs on yours? I'm finding it very worrisome that my screen could be faulty.

Searches say maybe logic board, but the guy I bought it from said it had a new logic board installed. Cables was a thought, but rotating iBook does not effect changes. I've shut it down for the moment, but am anxious to pinpoint the problem?

View 3 Replies View RelatedI have a 8x2.93 with 2 x 30" apple displays & the ati 4870.I have the displayport to dual-link dvi adapter to use both monitors.The monitor connected to the dvi port on the card is fine.The monitor connected via the adapter occasionally 'flickers' or kinda turns on/off very quickly.It's very intermittent. Often will go hours without doing it, but regularly does it 3-5 times a day.
I've tried swapping monitors around, and the problem follows the adapter.I've also got a 2nd adapter here spare (that I sometimes use for my laptop) that I swapped in as a test and the same happens.Smells to me like a firmware bug.I rang apple and amusingly they told me to run the vga firmware update. I told them it was not vga and they told me I still needed to run it. When I ran it of course the updating program said "no vga displays connected". Real smart advice there. They are looking into it and said they might be 5 days.

View 3 Replies View RelatedLast week I purchased a 20" Apple Cinema Display from Best Buy, it was a display model from the sales floor, looked amazing, I was actually looking for a 23" NOS but they gave me the 20" at a price I could just not refuse.
It was working great till last night, it begin to flicker certain pixels red where they should be black. Usually around the source of motion, for example the screen saver, the edges of the effect would flicker red instead of being black like the background. This was very minor at first but would progress to the whole black area flickering red, then go away, come back, so on and so forth. It actually did it once or twice when I brought it home but it was very minor and I dismissed it as being in my head, one of those "did I really see that?" type of moments.
Best Buy doesn't have any more in stock so they cannot replace it, they suggested I contact Apple for warranty support. Apple's website says the unit is out of warranty but I have sent them the sales receipt so they can update my purchase date, at which time, I should be covered and hopefully get my display repaired because I really do like it and it matches my office quite nicely.
My questions is regarding the worst case scenario, where my display is not repaired/replaced by Apple.
Has anyone had any luck determining the cause of these anomalies?
Apparently the flickering pixels is common among the older ACD family so I was wondering if the fix was out there. Maybe a revision "b" part of some sort that takes care of the defect.
My instincts tell me it's some sort of EMI/RFI issue, maybe improper shielding on something. Maybe a result of the power, dvi, usb, and firewire all being in the same sheaf. I'm sure the cable is shielded but maybe it's something that proved to be in adequate in certain environments and so a newer revised cable was released. I don't know, I'm just thinking out loud here.
I tested the display on my MacBook Pro, MacBook with the Mini-DVI to DVI adapter, and a Dell Desktop I have with an Nvidia card and the result is the same with all three computers so I'm sure it's the display.
The display is plugged into a UPS but it does the same thing when not plugged into the UPS in a different outlet in my home. I tired to move it around to different breakers to see if it was isolated to a certain outlet/breaker in my home, but they all give the same results.
I think I have an old ISOBar (power filtering power strip) somewhere I could try to see if it's a dirty power issue but my other monitors didn't seem to mind it if there is indeed a noise problem with my home's power.
I don't know... I would love to hear the thoughts of other users who have had and dealt with similar issues with their ACD.
im from Germany so my english is not the best =) But i try to explain what my problem is. I got a new MBP13 and im happy with it but there is something when i scroll down in this Forum here for exampe ... the text begins to flicker.
I dont know if it is the screen or a problem with drivers or anything like this. I tryed to make a video and uploaded it on youtube.
I want to know if you can see the flicker on this video or is it only me who can see this ?
Is this normal ?
