2014 Macbook Air check cable signal with Samsung Syncmaster 2494lw

I already posted this in the wrong thread. I have a Samsung Syncmaster 2494lw monitor that I am trying to connect my MacBook Air to 2014 el capitan running. I use a bolt of lightning to the adapter HDMI from Belkin to connect on the screen, then a DVI adapter to HDMI on the screen. When I plug in the computer, I get the "check signal cable"; However, connect other computers to the monitor works fine, including another mac. Does anyone have a solution to this?

Thank you!

  • No boot device error - early 2014 Macbook Air

    Forgive me if this has been posted elsewhere, I could not find another post as of yet with my set of circumstances.  I have a Macbook 2014 as shown air above 10.10.5 running and have had installed Boot Camp and windows 7 working for more than a year.  Recently, I tried to boot into boot camp and got the dreaded "No. Bootable Device" error.

    When I go to the startup disk in the settings I see BOOT CAMP Windows option to restart, but I get the above error when I restart.  When I restart and hold down the option I am not isolation presented with the option to boot into Windows or bootcamp.  I can see the boot camp partition in finder and disk utility.  I tried to create an installation disk Usb 2.0 with the latest version of windows software support in the Boot Camp Assistant.  I tried to use this drive to try to repair the disk, but cannot use the touchpad or keyboard or external keyboard.  Tried to use a player great external mac with a windows 7 dvd and had all the same problems.  I tried swapping usb ports and don't have anything yet.  I read somewhere that this could be a problem with the Usb 3.0 ports and drivers with windows 7.  Now I'm at a loss on how to recover it without having to reinstall.

    If I can see the data of the boot partition might be the problem?  I don't know what to do next. Any help would be greatly appreciated.

  • Pass an audition CS5.5 works don't not on 2014 MacBook Air

    Greetings!

    Just upgraded computers (on a 2008 MacBook) to a 2014 of MacBook Air (13, early 2014).  I had Audition CS5.5 on my old Mac, so I disabled it, installed on the new Air and activated.  Everything seemed to install smoothly, but when I open the program and open an audio file, it simply doesn't work, plain and simple.  I touched the game and nothing happens. I try with the space bar and nothing happens.  The play button lights up but nothing plays.  I can add effects to titles and see that changes are in the waveforms, but can not hear back.  Even after changing, I can't save these changes.

    The specifics:

    13 "MacBook Air (early 2014)

    1.4 GHz Intel Core i5

    DDR3 4 GB 1600 MHz

    Running OSX Yosemite (10.10.3, even my old MacBook with no problems)

    With respect to the hearing, it is CS5.5.  There do not appear to be updates available.  I know that I can go to CS6 and I have no problem to pay for upgrade, but it will only do it if I know for a fact that the issue will be resolved.  And honestly, unless there are updates that are earth-shattering, I'm perfectly happy with 5.5.

    So there.  Anyone has any ideas what could be the problem?  I did some research, but can't seem to find someone with I'm having exactly the problem.  Thanks in advance for any help you can provide!

    This means generally that the hearing cannot connect to the audio interface. You will need to check the settings in the Audio hardware / preferences of the hearing. You may also check the Mac audio and Midi to make sure that your audio interface is configured correctly. You have the correct audio drivers installed for your audio interface?

  • My Macbook Air 11 '' is compatible with a 1440 p (27 "monitor

    I've been "spoken in" purchase followed a resolution of 1440 p (rather than the 1080 p I initially had to buy) because I use several documents at the same time and was informed that it would be better for a 1440 p to be able to view side by side on a monitor. to see that it is from my Macbook Air 11 '' only supports a 1080 p resolution.

    Is it possible that I can improve my Macbook Air 11 '' (without having to buy a new Macbook) so I can benefit from the extra it cost me to purchase a higher resolution monitor? "  Specifications are the following:

    Graphics card: Intel HD Graphics 5000 1536 MB

    Processor: 1.7 GHz Intel Core i7

    I'm a complete newbie at this, but tried to go into my settings to display without result, only 1080 option is available.  Appreciate any help I can get in other words please :-)

    Thanks in advance

    I don't think you can upgrade your MacBook Air that its resolution is 1366 x 768.

    However, you should be able to go down this resolution 1440 p on your monitor.

  • Load OSX on 2014 macbook air problems

    Hey guys, dude this device telling me that he had bought earlier by someone who had deleted the info private and he has said that he needs to enter the password to access the desktop computer. The thing is, no matter what he tried it is not on the desktop, I think the OSX could have been deleted accidentally or not. I also think that the password which he received from the seller is a hard drive password and not osx password. As shown in the first screenshot, looks like this unit came with Yosemite and wants to go to Apple to reinstall, but when I try to do is to show an error. I tried to do a restore, but get a display of the error "Startup disk cannot be used as a source of food.

  • Why I can't have a decent resolution of my Macbook Air with an external monitor?

    MacBook Air 13 "(early 2014)

    I bought a Samsung S32E590C 32 '' nice monitor but cannot get above 1920 x 1080 @ 60 Hz (1080 p) using Thunderbolt to HDMI. The resolution is so low that I can't use the screen correctly. I'm afraid I won't be able to get a better resolution with my Macbook Air and will have to sell the monitor...

    Suggestions please.

    Hi sansthwaites,

    Welcome to the communities of Apple Support! I'm sorry to hear you're having problems with your MacBook Air and your new view. I'm sure we can help you understand what can happen.

    Based on your model described, it seems that the beginning of 2014 MacBook Air should be able to produce a somewhat higher resolution for a monitor external, as shown here:

    Graphics and video Support

    • Intel HD 5000 graphics card
    • Dual display and copy video: simultaneous support for native resolution on the built-in display and up to 2560 by 1600 pixels on an external display, both at millions of colors

    MacBook Air (13 inches, beginning 2014) - technical specifications

    However, the max possible resolution may be limited by the type of connection, or the specific adapter you use. For example, this Mini-DisplayPort-HDMI adapter supports up to 4 K (~ 3840 x 2160) resolution:

    Belkin 4 K Mini DisplayPort to HDMI adapter - Apple

    .. supported .While this Mini-DisplayPort-HDMI adapter only supports 1920 x 1200:

    Amazon.com: AmazonBasics Mini (Thunderbolt) adapter DisplayPort to HDMI: computers & accessories

    Then how you connect to an external monitor can certainly affect the maximum resolution available. In this case especially, however, I suspect that the issue is actually the screen itself, as it appears from the Samsung S32E590C screen to list a 1920 x 1080 max resolution:

    Support - curved screens S32E590C | Monitors Samsung

    I hope that was helpful.

    See you soon
