Mac book air connection to tv problem

I am having an issue with connection my mac book air to my tv. I am using a thunderbolt / Mini Displayport to HDMI adapter to connect to an sony TV. The computer screen shows up on the tv but both the tv and computer screens keep on blinking and changing resolutions. Is there an easy fix to this? The mac book has  an operating system of OS X 10.9.3 and the sony tv is a Bravia.

If I were having this issue, I'd try all the resolutions, plus I'd disconnect the cable and/or restart after every one, but that's just me, I like to try anything that might work.

    My mac book air connects to my network and gets internet access but airport utility  cannot find my airport base station to set up time machine

    airport utility  cannot find my airport base station to set up time machine
    Normally, AirPort Utility is not used or needed to set up Time Machine backups......unless a default setting on the Time Capsule to Enable File Sharing has been changed.
    On the other hand, if you open AirPort Utility, a picture of the Time Capsule should be displayed. Are you saying here that the Time Capsule does not appear when you open AirPort Utility?

  • Mac book air connects to internet w/ lag and drops

    my macbook air has been working for the past year, but recently my internet has been lagging and disconnecting by itself every 30 seconds. all my computers connect through a router and modem but only the mac air is having internet problems. it keeps saying "the page cannot be displayed" even though airport shows that it is connected to the internet. (note: the mac air works flawlessly when I connect to other wifi locations outside of home)
    router: netgear
    all the things I've tried.
    -editing keychain settings
    -deleting my network and creating a new one
    -resetting modem and router
    -resetting airport
    -changing dns and ip settings
    -resetting the mac air
    -turning off bluetooth
    -changing browser settings
    -smashing the router around
    nothing has worked....
    p.s. there was one day where I changed my router and it worked for one day, the next day it didn't work again.

    What are your wireless encryption settings? WEP, WPA2? Have you tried it with no encryption? Was it faster? Sometimes if you have rearranged the room or moved the router, interference can start. I also would download istumbler and see if you have neighbors using the same or adjacent channels. It will also show you the noise on your Netgear. Maybe this will bring some ideas to you:

  • Can a Mac book air connect to non wifi

    Can a MacBook Air connect to the internet without a wireless modem/router? (With a cord)

    Yes, it has its own Airport card, but you still need an Internet connection of some kind such as a Wi-Fi hotspot. However, in your own home you will need Internet service and a router. The service provider usually supplies the modem.

  • Mac book air connected to a dell screen shows only the background

    Why can I only see the background on my Dell monitor which is connected via the thunderbolt connection using a display cable please?

    Welcome to Apple Support Communities
    It's working correctly, but it's in extended mode. To put a window onto your monitor, drag a window to the right of your MacBook Air's screen. If you want to show the same in your Mac and external display, press Command and F1 keys. See > http://support.apple.com/kb/HT5019

  • Does the mac book air and mbp have problems

    does the macbook air have problems and the same things for the macbook pro

    I think the biggest problem they have are owners who insist on eating and drinking around their computer. The next biggest are former PC users who insist on installing anti virus software and after awhile attempt to "clean up" their Mac.
    Other than that, no, none that I'm aware of.

  • Can a latest Mac Book Air get connected to a display screen?

    Presentation at meetings require Mac Book Air get connected to a display screen.
    A Mac Book Pro is possible to get connected to a display screen using a A1307 adopter.
    Does any one know if the latest Mac Book Air connectable to a display screen using A1307 adopter or anyother means? I would be oblighed to know the possibility prior to buy one.
    Regards

    The Thunderbolt port doubles as a Mini-DisplayPort. Thunderbolt is not the same as Firewire. However, Apple does sell a Thunderbolt to Firewire adaptor so you can connect Firewire devices to the computer. Thunderbolt devices may be daisy-chained, but a display monitor must be the last device on that chain.
    According to what I found the A1307 adaptor is Mini-DisplayPort to VGA. It will not connect to a Firewire port.

  • USB Hub for Mac book air

    I recently got a mac book air. And the problem i have is with the USB port. Since there is only one USB port i tried using a 4-port USB hub. Which is working fine on any other Microsoft laptop. ut wen i tried to use it with my mac air it doesnt seem to be working. The funny thing is my mouse is working fine if i connect it through this hub. but my external hard drives are not registering through the hub, but they work if i direct plug it into the port of the mac air. Please help. As i really need the hub for my mac air.

    I have two USB hubs without a separate power supply. One is older (USB 1.1) and will drive an external hard drive, the newer hub (2.0) is more compact and will not support an external hard disk drive. I cannot find any listing of the power properties of the hubs themselves, or other hubs for sale, and so do not know which might work better. I suspect a non-powered hub is not ideal for an external hard disk drive.
    My solution is to buy a small bluetooth mouse and forget about using a USB hub for a mouse and instead use the port mostly for a USB flash drive.

    Your advice did not help me. I also installed 10.7.4 combo but the situation is the same.
    my internet connection is ok, mail is ok, but app store after 3 resets does not recognize my ID and it says "connection is not possible". Why? I have the same problem in both my mac mini late 2009 and mac book air 2010? Is it a problem of 10.7.4 update? I have to solve this problem and how can i return to 10.7.3 if my last backup was not with 10.7.3???thank you for your kind collaboration...

    I have been trying to share file between my Mac Book Air and PC Laptop.Sometimes my Mac sees the PC and tries to connect but every time the connection fails. It says server may not exisit or network problem. I have apparently no network problem. Thanks for any help you may provide

    hi,
    somewhere on the windows machineshould be something like "network setup wizard". exactly where it is and what it is called i cannot remember off the top of my head, windows help is actually slightly useful here, it should have a link to it.
    all the options checked on the mac are only what services the mac is offering to other machines, they have nothing to do with the services it can access (mostly...).
    oh yeah, to actually connect to the pc after you have turned its sharing on, use the finder, or, when it does not show the pc (this happens on and off, possibly a refresh problem apple...) choose go --> connect to server and enter smb://<pc's name or ip>
    to find the ip, the easiest way i think is
    start --> run --> cmd ->> ipconfig

  • I have a mac book air 11". When I boot up connected to the huge Thunderbolt  screen it detects the detects the fact and gives me great quality. now I am travelling away from the scree it boots up, nice picture, then switches to rubbish resolution.

    I have a Mac Book air 11". Normally at home I connect this to a large Thuderbolt Screen. When booting up it some times gets confused and offers me a low resolution result, but some plugging and unplugging of the screen fixes this. I assume it sometimes "sees" the big screen and sets the resolition accordingly. Sometimes does not. But now... I am away from big screen and cannot get the Macbook air on its one to deliver anything other than really poor resolution. I ahve done displays and chosen all three - but no better. And I have said Choose the Best ONe... again not luck. Any ideas. I read in back posts this was a problem a few years ago.

    Welcome to Apple Discussions
    I believe you have a failing GPU (aka Video Card). Run AHT and see what it tells you. Do not be afraid to run it up to three times in succession if at first it does not detect an error (sometimes errors that are caused by overheating will not show up until the computer is stressed enough - repeating AHT will do that).
    As an aside - the MBA was not designed to take the place of a desktop. If you are powering your MBA by leaving it permanently attached to the thunderbolt port on the monitor you are shortening your battery life.

  • I recently purchased a time capsule and thought I would put my itunes on it as an external drive as my mac book air only has 120gb. However I can not be connected to the internet and the TC at the same time in order to download the files to the TC. Help?

    I recently purchased a Time Capsule and put my iTunes library on there so that I wasn't using up my hard drive space. Only 120gb on my mac book air. However when I download songs from iTunes I can not be connected wirelessly to the internet at the same time. Can I hard wire my TC in to my mac so that I can treat the TC as just an external hard drive? Thanks

    Initially, you asked if you can hardwire your MBA to the TC. The answer is yes, by using the optional USB Ethernet adapter that Apple provides. However, in order for your MBA to access the TC's internal or USB-attached HDD, it would need to establish a network connection to it. This would be true of any NAS device on an Ethernet network. Therein, lies the problem. Your MBA cannot connect to two networks simultaneously.
    One option then, would be to have two separate iTunes Media folders; one on the MBA & the other on the TC. This way, you can download the music to your MBA when connected to the Internet at the AirPort lounge, and then use iTunes Consolidate Library feature to transfer the audio files to the TC's iTunes Media Folder location. A great program to help maintain multiple iTunes Librarys and/or Media Folders, that you may want to consider, is PowerTunes.

  • Mac book air Bluetooth internet connection

    Hi,
    I am trying to connect my mobile phone which is on vodafone in the UK through a bluetooth dial up connection on my mac book air. The phone connects to the mac, but when i press connect bluetooth DUN it tries to connect but fails to establish a connection and pops up that there is a problem with the modem are there any settings i need to change???
    Thanks very much.
    Tim

    OK so I uninstalled the anti virus software and iTunes is now showing the ATV in the device list again. However it still wont sync. It says it is syncing but the progress bar just shows the dancing diagonal lines but there is no progress made until it eventually just stops trying to sync. I have also tried to change the chanel on the airport express to several different options but it has not made a difference. Any more ideas?

  • My Mac Book Air has been hacked, and on top of that, they have unable me to connect to the Internet from my Mac Book Air. Anyone can help me?

    Hi!, my Mac Book Air has been totally hacked, and I cannot re/install my OSX because they have also hacked my Internet, so I cannot connect my Mac to the Internet. Any suggestions to fix my poor Mac Book Air????????????
    HELP..........

    It's best to describe the problem in as much relevant detail as possible, rather than what you think is causing it or how you think it should be solved.

  • HT204150 Following problem: I have around 600 contacts on my iphone and Ipad and would like to sync with contact list on my mac book air but its not working and whatever I do I get stuck on the 44 contacts I have on my mac  contact-list. Please Help!!!! 

    ollowing problem: I have around 600 contacts on my iphone and Ipad and would like to sync with contact list on my mac book air but its not working and whatever I do I get stuck on the 44 contacts I have on my mac  contact-list. Please Help!!!!  thanks

    First, be sure that the contacts on the devices are in the "icloud" section and not the "On my iPhone" (or iPad) section of the contact listings/groups.
    Missing contacts:
    Here's a test to perform - using a computer's browser, log into icloud.com and go to the Contacts page.  If most of them are gone, then they are gone. 
    If they show up, then the problem is that your device is not connecting to the Contacts database on icloud. 
    On the device, go to Settings>icloud.  Be sure icloud is on and using the right ID.  If not, scroll to the bottom of the page and tap Delete Account - this just disconnects the device from that account, no data is lost.  Then log back in using the correct ID.  ALSO - be sure the Contacts are turned on (on the same screen).
    Note:  Contacts are not part of an iCloud backup, since they are part of contacts database on iCloud's servers.   So performing a restore will not help.
    Contacts are gone from icloud.com.
    Then they have been deleted.  There are many reasons for this.  One possibility is that someone else is using the same iCloud account (family member, etc.) and they deleted contacts, thinking they did want them on THEIR device.  How to get them back?  Unfortunately, an iCloud backup does not include any of the sync databases, like contacts, notes, calendars, reminders, etc. because the data is already stored in these databases.  Your only hope for restoring the data is if you had that data on a computer (like a mac's Contacts, Calendars, etc.) and that data was backed up using whatever backup software you typically use (e.g. Time Machine on a mac).  Just restore the data files back to the computer.  Other than that, I'm afraid the data is gone.
