"No Signal" on my Samsung TV when trying to connect my MacBook Pro

When I try to connect my MacBook Pro to my Samsung HDTV it says no signal. My Pro doesn't flash blue or anything. I'm using a rocketfish adapter with an HDMI cable connected to it. I got my Pro in June 2010. Any idea on how to get this to work?

Hello TT31,
A quick fix you might attempt would be making visible, then clicking, the 'Detect Displays' button in the Displays pane of System Preferences. It can be made visible by holding the Option key once you've brought up the Displays pane (it will appear at the bottom right near the question mark).

If that doesn't get things working, I'd recommend taking a look through the following article, as it provides a whole host of useful troubleshooting steps for just such a situation.

    Dave I'm glad to say that it works perfectly but I'm embarrassed to say that my 12 year old nephew hooked it up in about 10 minutes.
    If you have the Kanex Mini DisplayPort cable it will work, what confused me was changing the display settings in System Preferences,
    and dragging the mac screen from the mac onto the tv. Sorry I cant be more helpful but you have the right cable now you need a 12 year old nephew.
    Good luck Derek

  • I'm trying to connect my MacBook Pro running on OS 10.8.2 to a Linksys EA3500 router and when I go to click on the set up icon I get an "unsupported operating system". Any suggestions on what to do? The Linksys site is useless.

    Don't use the CD software its not necessary.
    Infact put it in the trash.
    Your router will have an IP address in the range 192.168.1.1
    Connect your router to your Mac via Ethernet cable (They usually supply one with the router and don't worry which end goes where the Mac LAN socket is bi-directional)
    Also connect your router to your telephone line.
    Now open your Web browser Safari . Type in the IP address above and a Javascript control panel will launch
    Enter the default password and username (They are on a label on the router )
    Your now have the ability to set up your router.
    Your will need the password and user name supplied to you by your ISP at a minimum.
    Enter these and most modern routers automatically configure the basic networking setting.
    You now need to go to the security setting and set this as WPA2 Personal (NOT Enterprise) or WPA2 with AES and TKIP which ever it refers to and create a pass-phase. WRITE it down
    You should be online.
    Now remove the cable and connect to the Wifi and enter that passphase.

  • I am trying to connect a Macbook Pro to a projector for a Powerpoint presentation. When I use a VGA cable, the color of the projected images are not good. When I use a USB cable, the projected image includes the presenter notes on my computer screen?

    To move an iPhoto Library to a new machine:
    Link the two Macs together: there are several ways to do this: Wireless Network,Firewire Target Disk Mode, Ethernet, or even just copy the Library to an external HD and then on to the new machine...
    But however you do choose to link the two machines...
    Simply copy the iPhoto Library from the Pictures Folder on the old Machine to the Pictures Folder on the new Machine.
    Then hold down the option (or alt) key key and launch iPhoto. From the resulting menu select 'Choose Library'
    and select the Library that you moved.  That's it.
    This moves photos, events, albums, books, keywords, slideshows and everything else.
    Your first option didn't work because you imported one Library to another. Every version and thumbnail is imported like a distinct photo, you lose all your Albums, Keywords etc., the link between Original and Previews is destroyed, the non-destructive editing feature is ruined and so on. In summary: it's mess.
    Your second option didn't work because you simply referenced her library on the old machine.
    Regards

    I keep saying this over and over, in the hope that people who do a search will find it.  Apple cannot possibly test for or be reponsible for the bazillion combinations of adapter, cables, and TV's out there.  The only monitors that are 100% guaranteed to work with the MacBook Pro are the Cinema Displays and Thunderbolt Displays, because, they're made by Apple.  They're expensive, but they work perfectly.
    My guess is that you bought a cheap MDP to HDMI cable, or have a defective one.  From my reading of these boards over the past few months, cheap cables have a high failure rate.  And the regular priced ones have only a slightly less of one.  Try a new one.  Make sure you do not damage the Thunderbolt port.

    Depends on your model TV.   Read your TV user manual.  The newer models have "how to hookup" instructions for computer & games.

    to get to the Detect Displays button you have to hold down the Option key and the button appears.

  • Receive a "Server is Not Available" error when trying to connect win 7 pro PC to Windows Server Essentials 2012 R2 Domain via Connector

    I am trying to connect Windows 7 Pro 64 bit SP1 Computers to a Windows Server 2012 Essentials R2 domain and I receive the following error: "The server is not available.  Try connecting to this computer again, or for more information, see Troubleshoot

    All of these computers were already attached to a different Windows Server Essentials 2012 R2 domain.  They have all been taken off the existing domain and added to a workgroup.  I have uninstalled the Server Essentials 2012 Connector and deleted

  • Spinning wheel when trying to log into Macbook Pro 17" connected to 27" thunderbolt display

    I've got a 17" Macbook Pro connected to a brand new 27" Thunderbolt display.  When I attempt to log in from user screen I consistently get the spinning wheel of death and have to power down on  frequent basis.  More a nuisance than anything but with the amount of money invested on the components in front of me this seems slightly silly.  I can use this work around pretty easily, but my wife isn't real swift when it comes to these things so I'm looking for a long term fix. 

    lRlevolution,
    if your hard drive has failed, then no amount of resetting the SMC will fix your hard drive — you’ll need to purchase a new hard drive (or SSD), format it in Disk Utility, install it in place of the old one, and install OS X on it. (If you plan on installing it yourself, you’ll need a T6 Torx screwdriver to remove the four screws from your current hard drive and put them in your new drive.) Is there a reason to believe that there might be a motherboard issue involved?

  • Trying to connect a Macbook Pro with a G4 circa 2000

    Hi,
    I'm trying to connect my new Macbook Pro to my older G4 via an ethernet cable.
    I've turned ON file sharing in the network pref's on both machines.
    Have them attached directly to each other via an ethernet cable. I start up the Macbook Pro and then turn on the G4 but it doesn't show up as an option.
    When I click on the ethernet option in the network pref's it states that I'm not connected.
    I'm wondering if I should plug the ethernet cable from both the Macbook and G4 into my wireless router?
    The G4 isn't set up for a wireless connection so something tells me this won't work unless the hard wire from both simply serves as a pass through.
    Anyone have any ideas?
