Second screen with HDMI audio source after connection or wake

It is a very minor issue, but one I still dealing with.

I have a BenQ RL2455M monitor connected to my MacBook Pro w / retina with HDMI. I plug headphones to listen to music and talk on Skype on the plug headphones of the MBP. It all works perfectly.

The question arises when first connecting my laptop to the monitor (plugged the HDMI cable) or when waking up the laptop from sleep. If my helmet was left plugged in the headphone during this process, so I have no sound. Sound is sent through the HDMI. I have to unplug and plug in the headset to steal her back.

Of course, El Capitan is the choice the newest device to use for output. It makes sense, when you first connect the HDMI, but less after sleep.

In addition, this occurs when only my screen is in sleep mode and not my "computer". I changed this setting to 3 hours, because I had some programs that are not keep the laptop awake.

Hi, kaliblack.

Please visit Apple support communities.

I understand that you have an audio problem with your MacBook Pro.  Let's start with a memory NVRAM reset and then do a test to see if the behavior persists.

See you soon

  • Y510P image does not fit into the second screen using HDMI

    Hi, I have the Y510P with Windos 8.1 latest graphic drivers. I am connect to my HDTV via HDMI and the image fits well in my TV and it has a little zoomed. I was looking for a solution in all the menus of Intel HD 4600, nVIDIA Control Panel, Windows scaling... Nothing works. I have another laptop and it has an option that is changing the image and the TV shows that what is supposed to be for show.

    How can I solve this and did what I see in the screen of my laptop on the second screen (TV)?

    Thank you!

    I have a 1280 x 720 Samsung TV, I don't know the model exactly.

    The probem disappear when you change your screen resolution, or change the size of the elements, or something like that. It has something to do with the Panel of Intel, where there is a scaling option, in the tab 'display '. Well, there should be an option to select the scale, but it is not.

    So, to make it appear, you need to do this:

    1. connect the HDMI

    2 desktop, right-click, screen resolution, in 'View', you must select your TV, in my case "Samsung TV"

    3. you change the resolution from 1080 to 720

    4. then select Samsung TV as output ONLY screen, so the screen of the laptop turns off

    5. go in Control Panel (right click, graphics properties... office, display) Intel

    6. NOW, in the scaling box, you can move the 2 sliders and adjust the image, so now I can make it adapt to the screen

    Although it is a solution, and everything works fine, I don't like. I should be able to look at the screen of my laptop, and the most annoying is that steps 1 to 5 are reset every time you unplug the HDMI. It is a temporary solution.

    I want my nVIDIA GT 755 M to take control of the HDMI, I think that I could just plug the HDMI then automatically shows properly scaling the picture of my TV. Just plug and unplug, like all my other computers.

    Thanks for the help and hope I can find a real solution.

  • Black screen with flashing underscore concerns after removal of Rootkit

    HP Envy laptop (Win 7)
    Microsoft Security Essentials identified the Alureon trojan/rootkit, but could not clean after numerous attempts. I downloaded Malwarebytes Anti-Rootkit and it ran. He found and cleaned 3 threats. After completed cleaning, the laptop it will only boot to a black screen with a flashing underscore.

    I can access the boot, BIOS, System Recovery menu, etc. by pressing ESC at startup. However, I can't get into safe mode.

    There is an HP Recovery Manager option in the boot menu (F11) where you can access to Windows system restore, but also a few other options. I tried several restore points. Some boot worked but it is still in the black screen, other has no restore points.

    Thank you

    Hello

    In this case I suggest you select the option 'System of valuation (restore your computer to its original factory State)' - this will reinstall Windows 7, all software drivers and original, and all of the original scores.

    At the beginning of this procedure, you will have the option to backup your files (providing the files have not been corrupted)-this can be done for a connected external HDD or usb flash drives.  A full description of the backup process are under the heading "If you want to back up your personal files, follow these steps to create a back-up" on the following link.

    http://support.HP.com/us-en/document/c01867418

    Once completed, continue with the Factory Reset.

    **************************************************************

    Once the process is complete recovery, you'll always be able to create your 1 set of recovery on a usb flash drive media - the procedure is detailed in the HP document on the following link.

    Create recovery media - Windows 7.

  • How to make a dvd with an audio track after export using the media encoder? I have 2 separate files?

    Hello

    I just burn a video that I have completed. It's a m2v file and so I have a point of view audio AC3 and a video track. I thought I was ready to go, but I can't understand how to burn audio and video on the same disk. It's very embarrassing because the settings I should use for export to keep video quality will give me 2 separate files.

    So, what programs you use or recommend I would like to add an audio track? I don't want people to have the ability to switch between tracks, I just want a normal life trace that you have when you watch a movie, I mean he's playing just by default.

    Thanks to the adv.

    Mark

    Again is Adobe for DVD software, although there are others.  In General, the export of the elementary streams for use in an authoring application is the preferred method, then you are doing things.

    Specific help again, I would do you for the help file again.  If you decide to use another application, its own set of instructions will guide you.

  • 13 d-0016nl envy: problems with the HDMI audio

    Dear Sirs,

    Due to some problems with an engineering program I had to reinstall Windows 10 on my laptop. The version of Windows is the same of the one installed on the laptop when I bought it. Before the laptop with HDMI audio installation worked fine, but then, while the HDMI video continues to work well, the audio turns off directly from the laptop, such that the cable was not connected.

    I tried to activate the 'reproduction devices' HDMI connection, but I'm not able to do this because it's as if the cable is not connected, and the HDMI connection icon appears as gray.

    I tried to update the audio driver, but it didn't work, so I tried to download and install the latest version of these drivers from the hp site but neither this worked.

    Can you help me? The laptop is quite new and I would like to solve this problem without using 2 different cables to connect also a speaker with a cable to the because the HDMI does not work as it should.

    Thanks in advance,

    Martina.

    You are the very welcome, Martina.

    It would be the graphics driver you need install the HDMI audio driver...

    This package provides the driver that allows graphics Intel high definition (HD) in the notebook models that are running an operating system supported. If the video output high-definition multimedia interface (HDMI) is supported, this package also installs the HDMI Audio Driver.

  • input out of range with HDMI to VGA LE1901w

    Hello!

    Recently, I acquired a LE1901w monitor as a second screen. I'm trying to connect it to my Toshiba u925 using adapters HDMI / VGA (because neither the monitor has an HDMI port, or the laptop has a VGA output).

    I get the message "input out of range signal" requesting a change to 1440 x 920 @ 60 Hz and continues to display until the monitor going to sleep even when I change the settings according to demand.

    I have an integrated Intel HD Graphics 4000 and I use the default Windows for Windows 8.1 monitor drivers

    Any comments will be useful

    Thank you

    Hello @fbinim,

    I understand that you get the message "Input Signal Out Of Range" and it asks you to change at 1440 x 920 @ 60 Hz. I suspect it's a driver problem and you need to make sure that your drivers are up to date on your computer. Just to be safe, I recommend if you could to move the HP LE1901W monitor to another computer and make sure you do not have the problem. If you have it on a different computer the problem you are experiencing seems to be a physical problem. Please contact our technical support at the 800-474-6836.

  • Black screen with only the mouse pointer

    I just bought a Toshiba with Windows 7 laptop. Black screen with the mouse cursor after a few minutes of no use.  It seems to be the activity of the laptop but nothing happens even with a Control Alt Delete. I noticed after like 20 minutes, the windows screen comes back on.  Any ideas to solve this problem.

    Hello

    Since there seems to be a fairly new computer, you should check with the seller and the support from Toshiba
    for possible replacement and/or warranty repairs. Remember that do you more that they can
    It's something that you don't.

    Check with Toshiba support, their books online and the drivers and their known forums

    Black screen problems are extremely difficult to repair and all hotfix is usually a hit or miss

  • How to push the second screen?

    Hello

    I am writing an application in which I'm trying to push a second display to a custom in the first menu item. The first screen is pushed successfully and the custom menu items are filled with a bluetoothserialportlistener. Once I click on a special menu item, I want to launch the second screen. I used a dialog.alert to verify that the the menuitem run() method works, but the second screen is not displayed.

    Any suggestions are greatly appreciated!

    The first screen is created by hand (String [] args)

    MatMain app = new MatMain();

    app.enterEventDispatcher ();

    private MatMain() {}

    pushScreen (new WelcomeScreen());

    }

    I tried to call the second screen as follows:

    synchronized (UiApplication.getEventLock ()) {

    getUiEngine () .pushScreen (new MatOnline (_info));

    }

    I also tried:

    UiApplication.getUiApplication () .pushScreen (new MatOnline (_info));

    Thanks again!

    Hello

    I think you're trying in a very complex way.

    Your architecture using complex and ignoring the bluetooth codes related, I can see your second screen with a minor modification.

    In your DeviceMenuItem class.

    replaced

    MatMain.getUiApplication () .pushScreen (new MatOnline (_info));

    with

    UiApplication.getUiApplication () .pushScreen (new MatOnline (_info));

    And in your class MatOnline:

    replaced

    HorizontalFieldManager _fieldManagerOnline;
    with

    HorizontalFieldManager _fieldManagerOnline = new HorizontalFieldManager();
