HDMI with Alienware M14 trouble

Hello world

I am a French Dell user and I am new to this forum. I came here because I have problems with my hdmi (HDMI Out) connection with my computer Alienware M14 (I dunno which version R1 or R2). No source is detected on my screen after plug in the HDMI cable.

First, I checked my hdmi cable works well with other sources. Then I connected my PC directly to a screen HDMI and no source has been detected on the screen.

After that, I tried to connect the PC through a HDMI switch (powered by HDMI cables). It seems that my computer does not have enough power to power the power switch (very bad lighting of the diode). I said that the HDMI switch works well.

If you have any suggestions or solutions, please reply to this message.

Edit: All drivers are up-to-date

Have you tried to uninstall the video adapter driver and reinstall again?

    Hello

    Check with Alienware support, their drivers and documentation online and ask in their forums, because there may be problems with your model known. Perhaps all you need to do is update the audio drivers but it could also need to updates of BIOS, drivers chipset low level, and other drivers or custom programs (made by Alienware/Dell). Of course, the question could be material.

  • Bad output HDMI with Qosmio G30-153

    The display of the output to the HDMI port on two sets of HDTV in the mine is not as good as DVI or ATI 1800XL 7800GTX. The output of the screen seems to be scanned, where of course the taskbar and another part of the screen does not appear and the color screen is also poor.
    The resolution is correct, 1920 x 1080 and I use the latest Toshiba 8.3.2.8 display driver.
    I am disappointed by this expansive toy, hoping to play HD-DVD material, but with these display poor, no luck.
    I think that the driver is the question, but what can we do with Toshiba?
    Does anyone with G30-153 has the same problem?

    Kind regards

    Try 8.6.0.5 from here:

  • Problem HDMI with Satellite C850-175

    Hello

    My problem is that recently I bought projector Optoma GT750, unfortunately it doesen't work with my HDMI throught C850-175 (OS Win7 Home Premium 64) port. I have tryied all drivers Intel and Toshiba available for chart (Intel HD Graphics) but no luck there.

    The more anoing thing is that HDMI works with HDMI all equipped with TV I have tryied but will not work with projector Optoma GT750. It seams to be no communication at all when you use HDMI between the two. Not even a wink, I tryied many various HDMI cables including designated 1. 4 gold plated a HDCP-no luck there too.

    First of all ask, when using VGA port for conecting these two there is no problem at all for this to work, but I would like to use HDMI I don't need additional cables for sound.

    I hope that above is detailed enough for any tech minded to be able to determine what the problem is.

    I googled the problem and can not find a solution at all.

    Someone at - it had similar problems or maybe someone knows what it prevents these two see each other through HDMI?

    Thanks in advance

    I think it will be not easy to say why all this happens.
    Usually when you are using the TV and use the HDMI key combination FN will be there (the unit is detected).
    The same option is available when the projector is connected?

  • My screen is not clear on the mac mini, when you use HDMI with a TV monitor

    I have just bought a new Mac Mini and plugged into my TV with the HDMI cable. The display is not very clear, and in particular, the text seems to be very low resolution. Someone has ideas how to change settings to improve quality?

    What is the native resolution of the TV?
    What is the display resolution?

    Go to System Preferences > displays and look.

    Also dot the circle that says put across and what resolutions are available?

  • No Sound / Audio via HDMI with Satellite P840T

    Hi Forumites,

    I connected my Satellite P840T on my TV via HDMI Panasoni. Video works fine but no sound. The same cable and TV work fine with my laptop Del.

    I have read the forums, and we're talking about going into control panel > Sound > reading tab and selecting device HD Audio for playback, but on my P840T, IT IS No. HD Audio device for the indicated reading.

    I right click and checked the boxes to see the disabled and features show disconnected, but still nothing.
    I have download the latest drivers for the OEM Toshiba Intel HD4000 version show that the P840T seems to have, but still nothing. (The Audio drivers for the HDMI port part of the display driver right?)

    What else can I try other than to wait for the next version of the OEM Toshiba display Intel HD4000 version?

    Thanks in advance
    Mark

    > I have read the forums, and we're talking about going into control panel > Sound > reading tab and selecting device HD Audio for playback, but on my P840T, IT IS No. HD Audio device for the indicated reading.

    .. and what audio playback devices are available next to the speakers?
    In my case it is not peripheral HD audio but the Digital Audio sound called.

    By the way: what system are you using? Have you installed the new Windows or do you use the preinstalled Toshiba system?

  • No audio HDMI with Windows 7 Ultimate

    Since the departure of Vista with Windows 7 Ultimate, I lost audio HDMI.  I can connect video successfully to my Sony KDL46VL150 but will not come out through the home theater system.  It comes via the laptop.  I tried to update the drivers, but clearly, I have not found the right pair.  I tried as well through the website of HP, and Intel.

    The audio drivers in the system are now:

    Stwrt64.sys IDT High Definition Audio CODEC Version 6.10.6276.0

    Intel(r) High Definition Audio HDMI IntcHdmi.sys Version 6.10.0.2056

    I suspect that the HDMI driver is not 64-bit.

    Any other suggestions?

    Thanks for the tips.  I downloaded the drivers and the saved on the desktop as you suggested.  However, I could not find the graphics driver as you have described.

    I also followed the following suggestion I had to re-boot with the HDMI cable connected to the TV and it worked.  I see now that I have 2 identical drivers (Mobile Intel 4 Series Express Chipset Family) loaded in graphics cards.

    In any case, the problem is resolved.

    Thank you very much.

  • Problems with Alienware Aurora R4 Windows 10

    I had strange problems, especially since the update to Windows 10. Sometimes, I have no answer to click on in the lower left corner of Windows icon. Other times, it has a transparent background, etc. I was also at random to make a BSOD with IRQL_NOT_LESS_OR_EQUAL error. Here is a link to the dump file...

    I'm under BIOS A11, GTX690, 16 GB ram, i7 - 4820K @ 3.7 GHz. Those who know how to interpret the dump files can point me in the right direction?

    Thank you.

  • SX20. HDMI with audio and video?

    Hello.
    I have to integrate a SX20 codec with Extron HDMI matrix as the main source of video + audio.
    The main HDMI input, support with audio video integrated?

    Thank you.

    Luis

    We use the scalers Extron (DVS-605) to power the video (from several cameras in a provision of PiP) in our SX20s - however, we feed the audio through the mic connector.

    We have not tried audio HDMI at all.  The cards say it should work, but there is another discussion (ie the SX20 - Audio HDMI camera) where he says it's a bug with the documentation (CSCuh72577).

    The TC7 Administrator's Guide (Page 61) says that the HDMI Audio works that when using a camera with a built-in microphone Cisco, and, if you use any other device, the HDMI audio input will be disabled little matter however, you set the end point.

    The CE8.0.x software has removed the option "Audio input HDMI Mode" completely (Page 8 of CE8 Administrator's Guide).

    In short, I don't think you'll have some luck with your Extron HDMI audio, so you'll have to do as we did and feed your audio in via the microphone or the content entered.

  • Problems with Alienware M18x-R2

    This craigslist guy from whom I bought M18x-R2, 2013 (I know I'm a fool. I would not have bought which). I erased everything on my alienware. I noticed that my alienware is randomly freezing and slow. I watched youtube videos and it became too much freezing. I checked for mcafee antivirus scan and Defrag & optimize. Everything seemed to happen. My Alienware startup is like 5 minutes. I don't know why. Today, I checked to see if I have the warranty. He said his November 2014. How do warranty work? I've never done this before. Either way, I am deaf and sorry for the bad English.

    Alienware Specifications:
    8.1 Windows Pro (this guy told me he upgraded)
    AMD Radeon HD M 7970
    Intel Core i7 3740QM
    12 GB of RAM
    900 GB hard drives

    I recommend reinstalling Windows. Here is a video with step by step instructions.

  • DVI-HDMI with AUDIO

    I am trying to connect my new Pavilion p7-1240 to my HDTV but do not have a HDMI port on my new computer. After doing some research I'm to mix signals about whether or not a DVI to HDMI cable will carry audio. I just called Radio Shack and they are salesman told me that the AVIO HDMI to DVI cable carries the audio. However further research says that it is not.

    I would appreciate another opinion if you please. Bewilderment of a seller a week is enough. Thank you!

    Hello

    1. the standard DVI carries only video, standard HDMI carries both video and audio.
    2. DVI to HDMI converter adapter / (no need to convert) carries video only.
    3. you need a cable to carry the audio from your laptop to your TV. They can sell a combined adapter, but it must get out of the 2 ports on your laptop: DVI port for video and headphones or line out audio port.

    Kind regards.
