No Wireless Internet with External Display, Other Issues

Hello,
When I connect an external monitor to my MBA, I lose my connection to the Internet. The wi-fi signal remains strong, but pages will not load (I tried many) and I cannot retrieve email. The connection times out when I try to ping as well. This occurs whether I have the MBA open or closed. The loss of Internet happens immediately when I connect an external display using the supplied dongle, and returns the moment I disconnect it. It is clearly an issue with external displays.
On the advice of an Apple Genius, I also tried disabling bluetooth. I did so, and turned off all my bluetooth devices (Apple keyboard and mouse, iPhone), but the problems persist.
The other trouble I am having is difficulty connecting to a network for the first time in a session. In other words, I was connected all day yesterday, take the MBA home, and return to the office the next day. MBA takes a long time to see the network, then fails to accept the password. If I carry the MBA closer to the wireless router, it finds and connects automatically as I'd saved my password. When I return to my desk, I remain connected with full signal strength. This has happened in two locations, one with an Airport Extreme, the other with a Netopia 802.11g router. When my Macbook Pro is sitting right next to the MBA, it recognizes and connects to the same networks almost instantaneously.
Anyone have any suggestions? Much appreciated.

Just a quick update... I was on the phone with Apple Support on Saturday morning and I thought we were making progress. The basic idea behind the proposed solution was that there was some "Preferences" that were causing the problem. We started over with a clean Preferences folder and tried connecting up the external monitor. At first, this approach was showing progress. The suggestion was to copy over my original Preferences (I had made a backup copy) just a few at a time until we figured out which ones caused the problem. The problem with this approach is that immediately after I got off the phone, the internet started not to work again. So, even with a clean Preferences folder, the internet would quit working after connecting up the external monitor.
So, I'm back to the drawing board. I have since restored my Preferences folder and I don't have my external monitor and internet working at the same time. BTW, I also upgraded to 10.5.3 and it didn't help.
Still bummed,
Kevin

  • MBP Retina low performance with external displays

    Hi everyone!
    I have a very bad performance with my MBP 15´´ retina display when it comes to ad an external display. I have a FUL HD LG monitor that looks very bad when i connect the HDMI or the thunderbot port with the proper adapter (as bad as you can´t even read). I want to know if this may ba a hardware problem just with my computer or if it is a software problem, any ideas? does anyone have the same issue?
    How can i update my NVIDIA card???
    Thanks a lot!

    Topic seems to come up here often. Apple has a tendency to dismiss the issue.
    Its a pretty well known problem that Mac font smoothing doesn't seem to work well on high resolution third party external displays, making text hard to read. In addition, I think the Mac HDMI resolution support is limited to 1080p, so you must use DP or DVI video interfaces to see full monitor resolution.
    The OS default is no font smoothing on external displays (except perhaps the apple display). There is a terminal command that will enable font smoothing for any external monitor, but it often doesn't work well enough. I found that using the OS zoom feature magnifies text to the point to be easily readable. You can set zoom parameters in the accessibility systems preference panel.
    For some reason, sometimes the Mac OS thinks some monitors are TVs and use YCbCr instead of RGB. You can open the color sync utility and brouse the settings to see what is being used. There are scripts available that can fix that but are more complicated to install than an app.
    It seems that PCs are way ahead of Macs with external display implementation. Most folks having monitor problems with a Mac do not see the same issue with PCs or Unix/Linux OSs.
    Oh as far as updating the video card, can't. The monitor  "drivers" are built into the OS. When a new display is connected, the OS finds the profile for it.

  • Help with external displays

    Just installed Lion and afterward I noticed that things work differently with external displays. In the past I could have my laptop open to mirror but now it must be  shut and the mirrior button or selection isn't available within the display preferences. So my question is, 1. does any one know how to better manage displays? and 2. does anyone know how to mirror while having the laptop screen open?
    I know trhis sounds petty but where I work it is very hot and it seems like with the screen shut the computer syncs heat away a lot less efficiently.
    Thanks

    Thanks,
    I now know how to turn on and off mirrioring with command/F1 (didn't know that yet), but would you know how I can use my external display in mirror mode with the laptop display completely turned off, not dimmed till black, but off?
    Before lion I was able to do this by shutting the laptop screen which would put the machine  into sleep mode and then  by clicking the mouse or hitting a key on the keyboard it would wake it. Once the external display came on then I would open the laptop and the laptop display would remain off while using the external display. Hope that makes sense. Any suggestions?

  • Solution for sleep issues with external display?

    I had an Early 2011 Macbook Pro that worked quite well with an external display.  I now have a Mid 2012 Macbook Pro (bought 5 days ago, and running 10.10.3) that will not consistently work with the same external monitor.
    I had it working yesterday for a few hours only if I left the MBP with the top open (both the MBP screen and external monitor stayed lit).  But, today it is back to freezing each time the monitor is connected to it.
    I have tried:
    1.  Connecting the external monitor to the MBP with the top open.  Results in the MBP screen now going dark and no signal being passed to the external monitor.  If the external monitor is disconnected, the MBP screens stays dark and the computer is unresponsive requiring a hard restart.
    2.  Connecting the external monitor to the MBP with the top closed.  Results in no signal being sent to the external monitor.  Disconnecting the external monitor and reopening the MBP yields, again, and unresponsive computer which requires a hard restart.
    I have tried three different external monitors, all giving the same result.  The MBP is connect to external power, and I am running the latest OS (10.10.3).
    Any suggestions before I return this to the Apple store in a rage?  :-)

    Hello there, Gaflin.
    I'm sorry to hear you're having so much trouble getting your external display to work the way you are expecting with your new MacBook Pro. The following Knowledge Base article provides a great checklist of steps for troubleshooting the issue you seem to be describing:
    Apple computers: Troubleshooting issues with video on internal or external displays - Apple Support
    No video or no signal, image distortion, "snow," or flickering
    Check connections
    When using an external display be sure to check the following:
    If you're using an Apple notebook, confirm the AC power cable or adapter is securely connected to the computer and the cable providing power to the display is also secure. It is always good to have your notebook connected to AC power when an external display is in use.
    Confirm display adapters are fully seated in their respective connections and that they are supported models and for the computer and display. Refer to these articles to assist you with adapter compatibility and further configuration information:
    Monitor and Display Adapter Table
    About Mini DisplayPort to HDMI adapters
    Apple Mini DisplayPort adapters: Frequently asked questions (FAQ)
    Thunderbolt ports and displays: Frequently asked questions (FAQ)
    Remove all display cable extenders, KVM switches, or other like devices and retest to determine if the issue is resolved.
    Try unplugging the video adapter or cable and then plug it back in.
    If more than one video adapter is in use (or "daisy-chained"), troubleshoot by using only one adapter.
    Example: A mini DisplayPort to DVI adapter connected to a DVI to HDMI adapter is an unsupported configuration because there is a series of adapters in use.
    If available, try using a different display and or adapter (or use a different connector by using DVI instead of VGA, for instance).
    Reset the system
    You can reset the Mac's parameter RAM and SMC.Reset the resolution
    Start by resetting the Mac's parameter RAM. If the display does not come up, was previously set to an unsupported resolution, and still results in no video:
    Start up in Safe Mode.
    From the Apple () menu, choose System Preferences.
    Choose Displays from the View menu to open the preferences pane.
    Select any resolution and refresh rate that your display supports.
    Restart your computer.
    Using Closed lid, Extended Desktop, or Mirroring display modes
    When using multiple displays, information can be presented in a number of ways. For more information and what modes are supported by your Apple product refer to:
    Apple Portables: How to use your computer in closed lid (display closed) mode with an external display

  • Issues with External Displays on my Macbook Pro Retina

    Hello -
    My apologies for starting a second thread back to back, but I thought I'd keep these two issues separate
    I've been using two external displays off of my Macbook Pro Retina for some time - one off of the HDMI port and the other off of a Thunderbolt to HDMI adapter.  Everything was absolutely perfect until the most recent update.  Immediately after that, whenever the macbook wakes up, the two external displays go into this black and white snowy mode (like the HBO logo, or that thing from poltergeist) and takes a minute or two to start working properly.  Any suggestions on how I can fix this?
    Thanks.

    Hi there,
    Just browsed the forum and found a fix which solve the issue in my context: Google Chrome Play Music app was actually swallowing the media keys events, preventing iTunes to get them.
    Still don't really understand why it impacts only iTunes in my case, however once the Play Music app uninstalled from Chrome via the Extensions pane of the Settings page, iTunes got its media keys events back.
    See this thread for reference:
    Media keys not working on MacBook Air
    Cheers

  • Possible issue with external displays

    Ive been looking into why my latest and greatest g4 1.67 17" powerbook runs my copy of Aperture like a dog with 1 leg and i think it could be due to the external 23" display i use with this laptop.
    With that amount of screen, the GPU must have to allocate a fair amount just to run the display needed, thus distracting from the overall amount that Aperture is allocated.
    I know apple mentioned that external displays work well with the powerbook series, but what i feel they forget to mention that if you expect to run aperture with this kind of setup, your looking at a pretty slow machine full stop.
    Digging through the apple developer notes seems to confirm this and at the moment ive not been able to get any information from apple regarding this issue

    I doubt it. Your machine should have the 128MB graphics card.
    Internal screen 1680x1050x3 = 5.292MB for the main screen buffer.
    External screen 1920x1200x3 = 6.912MB for the main screen buffer.
    Even with extra VRAM taken up by Quartz Extreme, the external screen isn't going to be using a huge amount of VRAM out of 128MB.
    The real test, of course, is to see if the performance is the same without the external display.

  • Problem with external displays

    I've an issue with my MBP 15'' Early 2013. Recently I'd the GPU problem and my logic board was replaced. Everything worked fine as usual but I never tried to connect it to an external display.
    When I first connected a projector after the logic board change via a VGA adapter I wan unable to make it work, the computer had one of this two problems:
    Screen goes black and nothing works
    Computer gets too slow and I can't do anything but move the cursor
    Then I tried with a TV via HDMI and everything worked fine. I tried then with an external monitor, another projector and a TV with VGA and nothing worked.
    I searched in internet and most of the people has this problem with both VGA and HDMI. But I didn't found anyone with only the VGA problem.
    I tried resetting the PRAM, changing resolution to all the available ones and nothing worked.
    Before the logic board was replaced the external displays worked great.
    Any idea?
    Thank you!

    Hey, I had something similar happening with my i5 going to a Dell U2410, but my connection was via HDMI. When I got that distortion however I could not recover from it and had to reboot my laptop. I switched to an analog connector & noticed the occasional flicker to black, almost like my cable was loose and got bumped, but it recovered fine each time. I'm testing now with a dvi cable, and so far no issues *knock on wood*. Sorry, no fix, but maybe try a different connection and see if it improves things for you.
    Cheers!

  • Update to 10.6.8 colour problems with external display

    I have a mid-2010 13" macbook pro. I use a mini DVI to HDMI adaptor to connect to my Philips LCD TV. It has always worked perfectly including audio. Since update to 10.6.8 (yesterday) there is a colour-cast on the external display that makes it unusable. I have tried a hard reset of the mac with no effect except that the colour cast changed from green to red (strange!).
    Anyone had a similar problem or have any ideas how I could solve it? (no time machine so I can't downgrade unfortunately)

    Though I am using and iMac 27 and not a macbook, I have the similar issues since the 10.6.8 update.
    I too am using the adapter to connect to a Philips 42' LCD.
    You can see my post here: (has a pic of what my TV image now looks like since update.)
    https://discussions.apple.com/message/15488605#15488605
    I ended up going back to 10.6.7, not a fix, but no other alternative..
    I used to have this problem a year ago on a PC that happened to have the same ATi Graphics card. I just used the ATI control center and changed a setting to YBR component or something like that in some color settings. But unfortunately we don't have the ATI control panel for mac, least I don't think we have any kind of alternative, but would prolly fix it..

  • How to stop sleep/hibernation with external display & lid down

    What is the proper way to get my MBA to not sleep, hibernate, etc. when I have an external display attached and lid closed while watching a movie or webcast. In such a case I am not touching the mouse, trackpad, or keyboard.
    I have bluetooth keyboard and usb wireless mouse attached.
    I also disabled the sleep/poweroff options in the energy settings while watching.
    The MBA still would go to sleep or something after 10 or 15 minutes of no agitation.
    Also, the Monitor goes blank since their is not signal coming through to it.
    Was this just not a use case that was thought through: Watch video stream with external monitor and lid closed? Make sure the MBA knows this scenario invalidates the powersave options????? And yes, the power was plugged.
    Thanks

    Caffeine puts a little coffee cup icon at the top bar. Click to turn it off and on - it is on when the cup is dark, ie has coffee in it. However, this won't solve your problem - the MBA will still sleep with the lid closed. There are settings to allow use of an external monitor but what I did was download InsomniaX. This little free app keeps your computer from going to sleep when you close the lid. That way you can close the lid, walk down a hall or do something, then open the lid and keep working. Just don't forget it is on and leave the Mac too long or it will run out of battery.
    Insomnia isn't in the App store, had to download it at http://www.macupdate.com/app/mac/22211/insomniax

  • MBP randomly crashes when in clamshell with external display

    Hi Mac people.
    As described in the "subject field" i have been encountering some random crashes after i startet using my MBP in clamshell with my newly pruchased 24" 16:10 NEC display .
    typically it occurs after about 10-20 minutes of playing world of warcraft.
    -the screen goes black, saying no signal, and the MBP doesn't react to anything else but holding down the on/off button.
    i have tried using the key combination alt-cmd-eject to see if i could make the computer sleep and then turn it on by opening the lid.-getting it out of clamshell to get the built-in display active again.
    but none of that worked.
    i also checked the dvi<->mini-displayport adapter for lose connections but i didn't find any
    i have had my NEC display for about a month, and the problem has occured about 8 times now.
    befor i started using my MBP in clamshell with an external display, i had no problems.

    Surely, you've heard about the generic problems with this specific video chip: sooner or later most of them will fail due to chip packaging/bonding issues. If yours has not failed before, it may be doing so now because you're driving it harder with a larger external monitor attached, thus probably running the affected videochip hotter. Very useful link: http://www.xlr8yourmac.com/feedback/MacBookProvideofailure.html#novideotip , loads of other useful links on the subject therein.
    To solve this, Apple has instigated an extended warranty, so do not tread on the tail of your machine's capabilities any more. Once it will not boot (which may eventually happen), it gets really hard to run diagnostics. Have it checked by at least 1, preferably more ASPs (see link), and kindly ask them to reiterate the test 2 or 3 times. Often, the problem will not show up on the 1st try.
    I am reading increasing numbers of questions and complaints about this on the Flemish/Belgian Apple forum "Intermactivity", most users seem to be unaware of the problem (though this has been common knowledge for years), and moreover, most ASPs are reluctant to acknowledge it.
    So if your machine is one of the affected, you will really have to stand your case. Especially in Europe!

  • Not waking up with external display in closed clamshell mode.

    Hello all!
    I have the newest Macbook (late 2009), and have had it docked in a BookArc using an external display, keyboard and mouse. Everything has been working perfectly since I got it a couple months ago. I've traveled with the Macbook and redocked it at home a few times. This morning, I woke the computer and the display lit up as usual. A moment later, the display went black, said no signal and the power light went yellow (it's blue when operating). I hit the keyboard and clicked the mouse to wake it again to no avail. Took the Macbook out of the stand, opened the display and it works perfectly. Checked my energy saver settings, fine. Closed the clamshell, redocked, wont wake/start the external display. Took it out of the dock again, everything is fine, rebooted. Docked again, no wakey. I'm using it now as a normal laptop typing this. Any ideas as to suddenly why it wont wake/work with the external display? Thanks!

    Last week I bought an Acer X223W 22 inch display for my MacBook (13-inch, Late 2009) – Model A1342 Polycarbonate Unibody and an Apple Keyboard MB110LL/A - Also using a Apple wireless Magic Mouse but not a BookArc. ( Just leaving on the desk next to the Acer display )
    I've found that you have to have the MacBook connected to the AC Power Supply to keep the MacBook awake when trying to use an external display. It's kinda a pain sometimes, I usually boot up my MacBook before connecting the Display and Keyboard then once I'm logged in......
    and Once everything is loaded I plug in the Keyboard first then The Display adapter cable, Close the MacBook up then Click/Move the Magic Mouse ( System Preferences settings - Bluetooth ( Advanced: Allow Bluetooth Devices To Wake This Computer - checked ) Energy Saver AC and Battery set to 3 hours ( All other settings Unchecked )
    Sometimes takes a few clicks before the Desktop appears on the external display, Now once its on I can open the MacBook ( just enough to help keep it running cooler ) and unplug the AC Adapter unless it needs charging.

  • My T500 external display colour issue

    Hello all,
    Before I invoke my warranty on my laptop I thought I would try here first.  My external display all of a sudden today, started to turn yellow.  It seems like its random as to what exactly is being turned yellow, but it seems like almost every part of the screen is effected.  Some facts:
    1.  I have tried 2 different monitors and 3 different VGA cables with the exact same results.
    2.  When I first plugged the monitor in today and set it to output only to monitor, the screen was fine, when I changed it to 1680x1050, the yellow instantly showed up
    3.  Whatever resolution I try now, its always the same
    4.  I have rebooted, tried extended, clone and one screen displays, I have even tried rotating the display!
    So thats the story, my gut feeling says the video card in the laptop is the issue, but I do not know enough about it to be sure.
    Anything anybody can think of that I can try before calling it in?
    Cheers,
    Darren

    Does it work if you plug it into a different source? What if you plug the cable directly into the T500's onboard DisplayPort?

  • Kernel panic when trying to use spotlight with external display attached

    Having an issue with my fairly new MacBook Pro (purchased in April). When it's connected to an external display, I will get a kernel panic 100% of the time if I click on the Spotlight icon. The same also happens sometimes when clicking Documents or Downloads in the dock, but that is infrequent. This only happens with an external display attached and I have tried multiple external displays and cables. Following is the kernel panic report. I don't really know how to read it, so if anyone has suggestions they would be much appreciated.

  • MacBook Pro won't stay awake with external display AND power connected

    I've been using my MacBook Pro with an external 23" Apple display for several months, always with the lid closed and with no problems. Suddenly, I can no longer keep the MacBook awake when its lid is closed. *The AC power IS connected.* I plug in the display, close the lid, wake the system with my external keyboard, but then it will quickly go to sleep again after a few seconds. No matter what I've tried I get the same behavior.
    Perhaps coincidence, perhaps not, I installed the Leopard graphics update a few weeks ago. Could this be a cause?

    Apple did actually acknowledge this as a known issue with people running 10.5.2 with the graphics update, and are investigating it. There's some further discussion at this thread:
    http://discussions.apple.com/thread.jspa?threadID=1394449&tstart=0
    Anyway, what worked for me was powering down, connecting my external display, keyboard, etc., powering up, and immediately closing the lid. It seems to behave better now, though I haven't rebooted since, although I have switched back and forth between running with the external display, and running without it, without any problems.

  • External Display Resolution Issue...

    I have a Mid-2012 MPB running Mavericks. Recently, I've tried connecting 2 different external display's to the MBP via an Apple Thunderbolt to VGA adaptor. I can't get the resolution of the connected displays to go above 800 x 600, and it looks awful.
    The first screen is a Samsung SyncMaster T260HD with a native res of 1920 x 1200, and the other is a Samsung SyncMaster 933HD, with a native res of 1366 x 768. I plug them into my Windows box via a VGA cable, and it will drive each display at it's native res just fine. So what have I missed to get the MBP to do this???
    Thanks in advance. :-)

    My MBP has Thunderbolt and I have a mini displayport to DVI adapter. This is connected to the DVI port in the display.
    That option key selection did not increase the alternative resolutions available.
    I did reset PRAM according to a advise hee in the community. That did not help either.
