MacBook Air :: (10.9.3) Grey Flickering Screen After Connecting To External Monitor
Jun 2, 2014
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.
Info:
MacBook Air, OS X Mavericks (10.9.3)

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.
Model: PowerMac6,1
CPU-Type: PowerPC G4 (3.3)
and
the gfx chip is a GeforceMX4 with 32mb.
The display is a mode 9c27, manufacturer 610, serialnumber 00000, manufacture date: B84D7200.

I have a 28" inch display attached to newest version of Air. Works ok except when I have a full screen on plain dark grey background, then I see a waviness or flickering effect. Like the dark grey in Iphoto background. Other than this, the other colors seems ok. Pictures are fine, even when dark. Maybe there's a slight flickering with dark blue. Any explanations for this.
using mini display port to dvi. Tried with a friends dual link display, was a little different, but still unstable looking in dark grey when it fills the screen.
Could it be just what it takes to make this color, or the Hertz, which is 60. Other than this, no problem with the screen.

So, 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 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.

I have a Macbook Pro 2.16 Core Duo, and I'm wanting to install 10.6, but about a year ago, I cracked my screen to the point that I cannot make anything out on it, and haven't replaced it. Instead, I have just been using it in clamshell mode, which has worked out fine so far. My problem is that I cannot get the 10.6 install to show up on my external monitor.
I searched around, and could only find one other similar thread that just ended with the author putting it in clamshell and having it work fine. When I boot to the install and close the screen, I just get a grey box on my external display with a black bar on either side of it. I can't seem to find any other resources, so I'm not entirely sure what to do at this point. Any help would be greatly appreciated.

I just got a Samsung 2333sw monitor. When I plug into my 128GB SSD Rev B, it automatically uses the samsung as 2nd monitor. The screen is fully covered.
But when I select mirror (using the samsung as primary screen and turned the brightness of my MBA to the lowest), the samsung LCD picture is not clear and the screen is like 4:3.
Does this means that MBA can't support ext LCD as primary screen at 1080 resolution?
How about for those who has the new Apple 24" Cinema display? Can you use that as primary screen?

I've had my Macbook for about 3 years and have always been able to connect it up to my external monitor using a mini dvi cable.
A couple of weeks ago my hard drive died and since using the new one I cannot connect.
The external monitor shows my wallpaper but nothing else, no desktop, no dock etc...

I have been using my MBP (2010, i7 17" model) with a 24" HP external HDMI LCD monitor. The connection is via the Apple's Mini DisplayPort to VGA Adapter. It was working perfectly the first day I tried. However, when I connected the external monitor to the MBP yesterday, I found that the LCD screen of the external monitor was blinking. It lasted for about 5 minutes and then the problem was gone by itself. I have just reconnected my MBP to the monitor again. The problem reappears. Anybody knows what is going on and how to fix it?

I have used my ultimate 11" on usual mirrored display on battery power and in clamshell mode.
A few hours ago, I was running many apps in mirrored mood and my air just began to lag so badly after an hour. Expose is slow as well as surfing and clicking. I wondered what happened. Then I plug back power supply and close the lid of Air, hence running in clamshell mode. It then returned to full speed.
Please help explain to me if title is true. It is disturbing to learn that plugging into to ext monitor could lag.

I have an 15" Macbook Pro (Lion) with external HP monitor, which has been working fine. It is connected to Thunderbolt port via DVI.Today I connected the MBP to a Sony TV using Thunderbolt port via HDMI, which worked. When I switched back to the external HP monitor, colors were reversed on the HP monitor (you can read the contents but the colors are mostly green and pink). The MBP internal monitor displays correctly. I've tried rebooting the computer, resetting the HP monitor to factory settings, and deleting the HP monitor profile. No change.

I just got my Sammy HDTV/Monitor, which is a 23" 1080p HDTV. However, when I connect my MBP via my mini-displayport to HDMI adapter, the screen gets cut off on the top and the bottom. I have tried to switch the resolutions from 1080p to 720p, but it still does the same thing. It gets off both when I use the external as a secondary monitor and when I mirror the displays and use it as a primary monitor. When I turn overscan off in System Prefs, the 1080p image shrinks and there are black bars around all sides (however, it does show the entire screen). Does anyone know how to fix this? I want to get the most out of my recent purchase, and I know this is possible because I've seen it.

I've recently bought my first MBP and since I also have a Dell 27' monitor, I'd like to hook the MBP up to the big screen for movies and photo processings.
So given that mini displayport is the only video-out option on MBP and my Dell monitor only has a soundbar speaker (powered by the monitor but not built in), even if I got a mini displayport to HDMI cable (with audio capability) I would still need to connect that soundbar speaker to my MBP via the audio cable to get the sound right?

I bought a MBP and now want to create a office setup where I could use larger monitor, an external keyboard, and mouse for using the same MBP.
1. How to do this setup ? Is hooking an external monitor to DVI port to MBP good enough ? Can I use usb keyboard and mouse to connect to MBP ? Anything else ?
Can you please share your setup and anything that I should take care of.
What's a good place to buy these accessories ?

Hi- I have an ibook G4 (mid 2005). I'd like to be able to connect it to my new 22" external display so that I can have dual monitors. However, the external display plug obviously does not fit into the slot in the ibook.
Does anybody know the name of the converter cable I would need to buy in order to connect the external display to my ibook? And roughly how much these cost?

Macbook Air 13", Early 2014, 1.7 Ghz Core i7
120 SSD, 8GB Ram, OS X 10.9.4
External Monitor Compaq W185q
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.
Info:
MacBook Air, OS X Mavericks (10.9.4)

I am looking to connect my macbook pro to an Acer G24 monitor, but am not sure what best way to do it.The resolution of the monitor is 1920x1200, and it is a 24" screen, with VGA, DVI, and HDMI ports.My macbook pro is the late 2011 entry model.
Will there be a difference in the quality of the picture on my external monitor, depending on whether I connect using a HDMI cable or a DVI cable? I will have to buy an adapter for each of these, to plug into the mini DVI port on my mac, will this alter the quality of the picture at all? If I were to buy an Apple Tv, would I be able to plug it straight into my monitor using a HDMI cable? If so, how would I manage the audio, as my monitor does not have speakers. Would using a thunderbolt cable (with HDMI adaptor) increase the quality of the picture of my monitor?

MacBook Pro (13-inch Late 2011), Mac OS X (10.7.4), Apple TV, Thunderbolt, Monitor

I have connected my Aluminium Macbook (2008) to my HDTV via a Mini Display to HD port.This works fine when I mirror the image from my macbook. When I turn off mirror image however (IE effectively having two seperate screens) my internet slows down drastically. In some cases it also disconnects. This issue is resolved by turning on the mirror screen button, or unplugging the cable from the laptop.

I work on the macbook between 90min-2 hours throughout the day. At home, I hook up to a twenty-four inch monitor that I had calibrated through a Windows based system and complete my work. Now the files that I am working on are being processed through the macbook but viewed on the external monitor. I don't really care about the calibration of the macbook because the work that I am doing on it without the external monitor is really not color related i.e. removing scabs off of children, removing hair off of the face ect, but I need the final image to be accurate before it is sent off to the lab.
So, what do I need to do? Calibrate the macbook and the monitor or just the monitor and if just the monitor can anyone walk me through this? I know I could "search" but switching over from windows has been an experience and honestly, I am tired of "searching". Speaking of searching, I am still trying to figure out a way to sync my Dell x50v to the macbook, anyone? I know the x50v is old but it is the most solid piece of windows hardware I have ever owned and it still "just works".

I have a white MB (early 2008). I'm going to be getting an external monitor soon with a native resolution of 1920x1200 - the highest that the MB's Intel GMA X3100 will support. I know that I can open System Preferences > Display and then click the little menubar and drag it to the other monitor to make it the primary. Here is the thing: I want to just use my 24" monitor and not use the MB's screen with it (I have an external keyboard and mouse).
Should I...
1. Use the two displays as an extended desktop and then (leave the MacBook lid open) just turn the brightness on the MB all the way off so the screen is black (no back light)?
or...
2. Just close the MacBook and use it in clam shell mode? I watch Hulu and YouTube a lot which causes the CPU load to increase and fans to spin up.... do I have to worry about over heating? I would be using the 24" monitor exclusively all the time and then take the MB when I go to class. Will this just ruin my MB pre-maturely?

My 2006 mMcBook is dead and parted out. I still have the case and screen, but no HD, RAM, battery, or working logic board. How can I take the screen and make myself an external monitor out of it? I am presuming it's possible. I can solder a little and I love messing with parts from radio shack. So, has anyone heard of this? I tried googling it but couldn't find any search terms that brought me what I wanted.
Basically, I want to convert the video cable to DVI or even better, Display Port, and then figure out how to solder in a power source to just plug into a wall (since I'm assuming it'd be too big of a job to have it powered off of the FW800 or USB from the macbook pro). Is this possible? Since the computer is dead and gone, it won't hurt to experiment. Anyone have any links or guides to this?

I am attempting to use an external DVI monitor using the mini port port and the mini port DVI adapter sold by apple. However the screen display on the external monitor does not match the Mac book display. All I get is a color Mac opening screen with no icons.apparently there is more to getting an external monitor going then just plugging it in.

Has anyone noticed a very slight flicker on their new MBPs? I have a new 13" and, every so often, the screen brightness dims and then brightens very quickly (happens in less than a second).The option for auto-adjusting the screen brightness is off so it's not that particular function.It's most noticeable on all-white backgrounds both on AC and battery power. Hard drive access doesn't seem to coincide with the dimming.

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?
