How do i use my HDMI cable with my macbook pro?

I just bought an HDMI cable and an adaptor to use with my Macbook Pro and I am having trouble setting it up correctly. I have it hooked up to my computer and TV and when I open my computer the galaxy screen savor just stays on my TV screen. What do I do?

Have you opened SYSTEM PREFERENCES>DISPLAYS?  You make your settings there. For details, please look at the column on the right labeled 'More Like This'.
Ciao.

    How do I use an external display with a macbook pro?

    Just buy the proper adapter cord, such as MiniDisplay port to HDMI for example.  Plug it in and it will be automatically recognized.  Use System Preferences > Displays to set options.
    The display can Mirror your primary desktop or Extend the Desktop.

  • How can I use an A1082 monitor with my MacBook Pro?

    I received an apple A1082 monitor this past weekend from a friend and we couldn't, and still can't, figure out how it can be used with my MacBook Pro. I know that I need an adapter, but where does it get power from? Thanks in-advance. Richie.

  • Cant hear audio using an hdmi cable from my MacBook Pro to an HDTV

    i'm trying to watch video and streaming video from my McBook Pro on an HDTV via an HDMI cable.  i can see the video but there is no sound.  help?

    What year was your Mac made, IE what Model year is it and what model is it?
    With newer Macs all you need is a good Mini Displayport to HDMI adapter, I know the Griffin model work as I have one, and a HDMI cable.
    If a Retina model that has a HDMI out port then you don't need any adapters of any kind. Just a cable from HDMI to HDMI ports on Mac and TV.
    Once you have a good adapter, if you need one, and the cable is connected to the TV go into System Preferences and the Sound Applet and there should be an option in the Output section for HDMI. Enable that and the sound will be sent over the HDMI cable to the TV.
    If you have an older Mac computer then you may need to use a separate cable from the Mac headphone out port to a Line In port on the TV

  • How can I use a USB keyboard with my Macbook Pro?

    My MBP will not recognize my brand new USB keyboard.
    I have tried the keyboard on two other Macbook Air's and it works perfectly.
    My MBP:
    OS X Yosemite
    10.10.1
    Macbook Pro (Retina, 13-inch, Late 2013)
    2.4 GHz Core i5
    8GB 1600 MHz DDR3
    Mac HD
    Graphics Intel Iris 1536 MB
    Thoughts on how I can resolve this issue would be greatly appreciated.
    Thanks,
    Greg

    Brenden,
    Thanks for the reply.
    I've gone your suggestions in detail and the keyboard is still not working.
    From what I can tell this is a known issue with Yosemite.

    Someone at Apple must be able to figure this one out.

  • How do I use two external monitors with my MacBook Pro?

    I have a 21" monitor and a 20" TV capable of VGA connection, and my MacBooks model is 5,4 (late 2009), so it only has one mini display port. I have a VGA to mini display connector and use it lots. I work on multiple projects at once, and I'd like to be able to use three screens at once... any suggestions?

    Just buy the proper adapter cord, such as MiniDisplay port to HDMI for example.  Plug it in and it will be automatically recognized.  Use System Preferences > Displays to set options.
    The display can Mirror your primary desktop or Extend the Desktop.

    I am using duel thunderbolt displays with a MacBook Pro. I only have the option to have sound come from one or the other. Has anyone thought of making the left channel come from both speakers on the left Monitor and the same of the right? If yes, how is that done? The MacBook Pro could even be a center channel if configured in that order.

    See the following thread on the same topic:

    Hi,
    System Preferences > Accounts > Your Account
    Select current  Pic and chose to Change it.
    You get an option to take a SnapShot.
    Quicktime will also be able to access it and record using Quicktime  X in Snow Leopard.
    Check the Menu items for New Recording.
    MSN for Mac can use it (It depend on version and in some cases whether you are connected to the correct type of Windows server)
    Yahoo (This is in Beta 3 and has been for years)
    Results can vary.
    A Web Browser with the Flash Plug-in active can access the camera on certain Web Sites that run video Chat rooms
    See Koowy
    (Type anything to Create a Room Name
    On the New Page allow access to the camera in the Flash Pop Up - You may need to use the tabs to Select Camera type.

    If there is no loading bar, it's usually a problem with a third party kext file in OS X itself.
    You can press the power button down to force a hardware shutdown, then reboot holding the shift key down on a wired or built in keyboard, this will disable them and you go around and update your third party software.
    Gray, Blue or White screen at boot, w/spinner/progress bar
    Also take this time to backup your users files off the machine if possible.
    Most commonly used backup methods
    Sometime that won't work and you need to do more

  • Can I use an USB disc with my macbook pro bought in 2005.  What capacity will it take 2.00 or 3.00?

    can I use an USB disc with my macbook pro bought in 2005.  What capacity will it take 2.00 or 3.00?

    The first MacBook Pro's were not released until the beginning of 2006, and they had USB 2 ports.
    Anything available new in 2005 would have been a PowerBook G4 and they also had USB 2 ports.
    A USB 3 disk will just transfer data slower then it could do, if you plug it into a USB 2 port though, so you can buy either.

  • I have a 2010 vintage 13-inch MacBook Pro that has a 60 watt power adapter.  I also have an older power adapter that is 65 watts.  Is it okat to use the 65 watt with this MacBook Pro?

    I have a 2010 vintage 13-inch MacBook Pro that has a 60 watt power adapter.  I also have an older power adapter that is 65 watts.  Is it okat to use the 65 watt with this MacBook Pro?

    yes.
    "For instance If you have a MacBook (13-inch Late 2009) that normally uses a 60W adapter, you can also use an 85W adapter with that computer. You would not use a 45W adapter with that computer; it would not provide enough power for that MacBook. Using an adapter of higher wattage than the adapter that came with the computer will not cause the computer to charge more quickly or otherwise operate any differently than using the adapter that came with the computer.
