MacBook Air :: External Monitor Flickering?
Aug 31, 2009
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.

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.

MacBook Air, OS X Mavericks (10.9.3)

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.

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?

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.

I have a Late 2011 MBP, just recently I also go an Xbox and wanted to hook it up to my external display that I have been using for a long time with no issues. I went and bought this: URL....to be able to easily switch between the two inputs. The xbox works fine, however when I view my Macs input the screen flickers a static image very frequently.
I know what you're thinking, it's probably an issue with either a cable, or the device. But when I boot into Windows via Bootcamp with the same exact setup, there is no flicker at all. The display is a dell s2440L, the HDMI adapter is a rocket fish.
Here are the troubleshooting steps I have tried: Resetting PRAM/SMCChanging out HDMI cables on both the Splitter output, and the inputs (I tried 3 different cables on both the inputs, and outputs.)Downgrading OSX to 10.7 (And then went back to 10.9)Lowering the resolution on the monitor (Lower resolutions flicker just as much, if not more.)Resetting the splitter by unplugging the HDMI cord powering it and plugging it back in.and of course, plugging my computer into the splitter input that the Xbox works fine on, as well as taking the xbox one out so the computer is the only input on the splitter.
Like I said, the Xbox works fine, and even the computer works fine in Windows, but whenever I boot into OSX my screen flickers with this static. I should add, the display works fine when not connected to the splitter on OSX.

I picked up a new MacBook yesterday and I noticed a weird issue when coming out of "monitor sleep" mode, not regular sleep mode.
When I move the mouse, the external monitor shows what you see in the picture, kinda like a TV with no signal. The MacBook screen works fine so what I just do is unplug and re-plug in the DVI plug and everything is good again.
My 24 inch Dell monitor worked fine with my M1330 and other computers so I know it's not that. Does anyone have the same issue or maybe give me some light on this?

I have a 22" Dell external monitor on my MBP. I know that I just close the cover to my MBP to shut off the screen. What do I do in those instances that I want to use both screens? There has to be something simpler than restarting the MBP?

As said, my current set up is an HDMI - DVI cable (HDMI to monitor and DVI to adapter) and my DVI - mini DisplayPort adapter, everything is connected fine but when I turn on the monitor, it says cable not found... and nothing is displayed on the screen but on the Macbook side of things, it sees the monitor is connected (I can extend the screen and leave the screen) but other than that, it appears I cannot get an image on the monitor, pressing every button on the monitor does not work either.
Any other information that may seem necessary, let me know. I tried clearing my PRAM and clearing the power and such but nothing seems to work.

I have a 27" i7. I have a 24" DVI Montior hooked up to it via MDP->DVI adaptor. When the 24" Monitor is on, everything is fine. When I turn the monitor off, the magic mouse tracking on the 27" screen stutters. I am not kidding - it took me ages to figure out that to fix I either need to turn the other monitor on OR disconnect the MDP->DVI adaptor.

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 G4 powerbook with an LCD that only displays the top 25% of the screen. I've been using an external monitor with it just fine. Today, I reinstalled the OS and ran into a problem. The main OSX startup menu (you know, where it asks for your location, timezone, personal info, etc) is prompting me for information, and I can't see the forms to fill them in! The external monitor defaults to "extended" as opposed to "mirrored", and the forms are embedded, meaning I can't drag them over to my external monitor. Obviously, if I can't fill out these forms and get to the desktop, the laptop is completely useless.
Does anyone know how to force the external monitor to be "mirrored" from startup? Is there a keycommand?

I have been using the latest macbook pro 13.3" since April 2010. Over the last week the monitor suddenly goes completely white and the external monitor goes black. The laptop becomes unresponsive although the programmes opened continue running (e.g a skype voice call would continue without interruption although the monitor is all white).
The only solution at the moment is to press the turn off button for a few seconds then switch the laptop on again. It will then work normally until for no apparent reason this happens again.

I have my MacBook Air hooked up to a 46" HDTV so that I can play games on the big screen.
Problem is, I notice a slight lag with the mouse when looking around in the game on the big screen.
When I look at the game from my MacBook Air there is no lag with the mouse.
I heard theres a mode called "clamshell" that would fix this but don't know where to find it or enable it.
Info on fixing the lag from the big screen so that games could be playable when watching from the big screen.

I have a 2.0 white macbook but am thinking of upgrading to a unibody. How do I connect to an (either model) external monitor and can the MB be closed and still be "on". Someone I know told me they had a docking station for their Dell but I'm not really looking to buy more equipment. So I'm looking for suggestions on how to do this.

I got a fairly nifty AOC 16" USB monitor from TigerDirect.it isn't totally Apple-Quality, but its bright... looks decent at 1366x768... and I got the color of the windows to almost completely match. I would suggest the AOC USB monitor to anyone looking for a cheap way to get a 2 monitor setup. And, it runs from a USB port only... no need to plug it in. Very nice. One drawback of this model is that it does have protrait AND landscape modes... there is a stand on the rear that you twist and can stand the monitor up on its end. However, the Mac drivers don't support this feature! Shucks! I had grandure thoughts of having a document in portrait mode all tall and beautiful. OR, a killer long Facebook window. But alas, this feature will have to wait for now... man, if AOC can release a new driver with this feature; I would say this $140 monitor is a KILLER. Still reccommend it.
First, when I connected it the monitor was aligned or setup on the left hand side... I want the NEW 16" monitor to be on the right hand side just as an extra screen space... so, I opened displays and moved the alignment. I noticed you can go up down left or right... which is cool. So I set it up for the right hand side, so when I scroll off the MBP screen to the right the cursor just goes over to the new screen. Great. However, the dock and toolbar are on the NEW 16" monitor no matter what I do! I want the dock and toolbar on the MBP still; and the new monitor just sitting there ready for me to throw any STUFF on it. How do I do that?
Also, when I use that multiple desktop feature... lol, I forget what its called. Each desktop switches the new 16" monitor to whatever # of screen I'm on. I can live with that if its the only way. BUT, better for me would be if the MBP has the dock and toolbar... can switch between those different screen #s... AND, the new 16" just sits to the right as extra space. So when I switch screen #s, the new 16" stays the same with whatever windows I have open staying there... this might not be doable, and that would be OK... but wondering if theres a way to do that too...

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'm running an older 24 inch cinema display on my MBP and am looking to add second 24 inch monitor for use in FCP. My only cheap option seems to be a USB gizmo, something like this [URL]. Anyone have any experience with this device, specifically with FCP 6; I'd like to use the second monitor to playback the footage in the viewer so I don't think the device needs too much horse power but the footage will be in the ProRes 422 format.

I have an early 2010 13 inch macbook hooked up to an AG neovo F-417 monitor. Now i can get it to connect in both mirror and clamshell mode, but it seems to black out on me every few seconds ranging from 20 to sometimes a few minutes, switching back to the macbook screen.
I have basically tried to use every possible screen resolution but the blackouts won't go away.
is it possible that it is an incompatibility issue?

I recently bought a Macbook, and I've been trying to connect it to my external Samsung SyncMaster P2270 screen using a DVI-to-miniDVI adapter from Apple. It works, both as extended or mirrored screen, but the maximum resolution I get is 1600x1200 (and I actually use 1600x900, cause it looks distorted otherwise).
Any clues on how to get it to output 1920x1080? I'm sure that the screen supports that resolution, because I've used it before with another laptop.

Just bought a new 22' LG monitor and I have the Mini DisplayPort to VGA. When I connect my monitor to my MacBook all is OK until I try to chose the 1680x1050 which is the LG's prefered resolution. When I chose it, my monitor turns to black, then after a while it shows the picture for a second, then black again.. Is this a 9400m fault, or the VGA adapter fault?If I try a MiniDisplay port to DVI, will it work in 1680 x 1050?
All the other resolutions are shown ok..
