Output HDMI not working do not after Windows 8.1 update

I use an envy TouchSmart 15 and I just launched an update of Windows based on the automatic system update 8.1 (he ran 5 updates).

Before the update, I've used a 27 "monitor in the main screen, and it was connected via the HDMI port.  Just after the update, the system does not recognize the HDMI port and more and this goes back to the use of the screen of the cell phone Envy as the main screen.  I changed the HDMI cable but it made no difference.  I am connected subsequently another laptop to the monitor 27 "via HDMI and it worked fine.  So it appears the monitor and the HDMI cable are fine.

Please can you help me?

Hey yawbus,

I would firstly you welcome on the HP Forums!

Thanks for sharing the troubleshooting steps that you already have, and I say you are right that the issue is not with the HDMI cable or the 27 "monitor. From what you described in your post, it sounds as if he is with the drivers, maybe a conflict.

I would like to begin with the installation of the original video drivers supplied with your laptop. I've included the document "using Recovery Manager to restore the software and drivers (Windows 8)". Please follow the steps to reinstall everything video original drivers. After you have installed the original drivers, restart your computer.

Now, once the computer is restarted, you will need to install the updates that are available for HP and Windows. You can install both of them through the HP Support Assistant. I've included the document 'using HP Support Assistant (Windows 8)'. Scroll to the bottom of the page on to Midway, and you should see an option for the updates and the updates. Please follow the options for HP and Windows updates.

If you are still having the same problem after the above troubleshooting steps, please let me know the model number full of your envy TouchSmart 15. I've included the document 'Guide to finding your product number'. So, please confirm the current version of Windows that you are running. If you need help to find the version, I've included the document 'operating system Windows that I am running?'.

Looking forward to your reply!

  • Audio not working do not after Windows 8.1 update

    Hello

    A few days ago that I have updated Windows 8.1 evaluation to the full version 8.1 and since then my audio doesn't work. In Control Panel, "Digital Audio display (AMD high definition Audio Device)" is listed as disconnected. The audio icon on the taskbar is XE out and clicking on it works the finder error in vain. Speakers no longer appear in the list of devices well now that nothing works I don't know if they have ever or if the audio comes through display Digital Audio. Headphones do not present as playback device and the volume on the keyboard controls and the taskbar are not accessible. I've never used external speakers.

    Windows 8.1 update seemed to wipe all my software HP and AMD came with the laptop so I reinstalled the HP support center and looked for a driver updated and all that jive, but all also shows to date. I don't know what else to look for because most of the forums I've seen seem to speak of their output HDMI sound does not work when it is connected to a TV and I just try to have sound, period.

    Hi Chris,

    Try the following.

    Download IDT Audio Installer on the link below and save it in your downloads folder.

    http://ftp.HP.com/pub/SoftPaq/sp59501-60000/sp59861.exe

    One time finished, open windows control panel, open Device Manager and open sound, video and game controllers.  If you see a very similar entry for (or entry of IDT) IDT HD Audio , right click on the device and select uninstall - you should also get a command prompt to delete the current driver, check the box allow this and then proceed to uninstall.  If there is no input IDT, go just below.

    When you're done, shut down the laptop, unplug the AC adapter and then remove the battery.  Press and hold the Power button for 30 seconds.  Reinsert the battery and plug in the AC adapter.

    Robinet tap away at the key esc that you start the computer to launch the Start Menu, and then select f10 to open the bios menu.  Press f5 to load the default values (sometimes it's f9, but the menu below indicates the correct key), use the arrow keys to select 'Yes' and press ENTER.  Press f10 to save the setting and still use the arrow keys to select 'Yes' and press on enter.

    Allow Windows to fully - charge it will automatically load an audio driver, but let just this complete.  Then open your download folder, right-click on the IDT Installer and select "Run as Administrator" to launch the installation.  Once this done, do a right-click the speaker icon in the taskbar and select playback devices.  'Speakers and headphones' left click once to highlight, and then click the Set Default button - check if you now audio.

  • WIndows, internet Explorer does not not after the attempt to update windows

    Windows stops responding and lights that shows cpu works doesn't Flash at all.
    Whenever I try to use windows update, my computer crashes while updating.

    Hello

    Updates are closely related to IE.

    Try these and it can also be a good idea to update your main drivers later. The General corruption can also play a
    role in this issue. And even the TCP/IP stack might need to be refreshed.

    What antivirus/antispyware/security products do you have on the machine? Be one you ALREADY had on this
    machine, including those you have uninstalled (they leave leftovers behind which can cause strange problems).

    If no joy there's something blocking perhaps.

    Start - All Programs - Accessories - System Tools - IE with no Addons - what works best?

    IE - Tools - Internet Options - Advanced - tab click on restore, and then click Reset - apply / OK

    IE - Tools - Internet Options - Security tab - click on reset all default areas - apply / OK

    Close and restart IE or IE with no addons

    not better?

    IE - tools - manage Addons (for sure disable SSV2 if it is there, it is no longer necessary but Java always install
    "(and it causes problems - you never update Java to go back in and turn it off again)." Search for other possible problems.

    Windows Defender - tools - software explore - look for problems with programs that do not look right. Permit
    are usually OK and "unauthorized" are not always bad. If in doubt about a program to ask about it here.

    Could be that a BHO - BHOremover - free - standalone program, needs no installation, download and run - not all
    are bad, but some can cause your question (toolbars are BHO).

    Hello iwasbetterbutgotoverit,

    1. do you have an update of the hardware installed on your computer?

    2. what exactly happens when you try to print from the printer?

    I suggest that you try the methods below to solve the problem.

    To restore the operating system to an earlier point in time, follow these steps:

    a. Click Start, type system restore in the search box and then in the list click on the system restore program.

    b. If you are prompted for an administrator password or a confirmation, type your password or click on continue.

    (c) in the System Restore dialog box, click on choose a different restore point and then click Next.

    d. in the list of restore points, click a restore point created before you started having the problem, and then click Next.

  • OfficeJet 7200 series: Images print do not after Windows 8.1 upgrade

    I had the problem of images not current print some time ago and I was directed to this forum for a replacement printer driver that fixed the problem... that is until I upgraded to Windows 8.1. The Windows Installer to update replaced this driver with another and no trace of it. I don't remember his name, but it is generic in nature.

    Hi @joefredt ,

    I understand that you encounter problems, printing images since the upgrade to Windows 8.1. You used a generic driver previously with Windows 8 that solved the problem. I will do my best to help you today.

    From the start screen, (menu tiles) type in "Devices and printers", select settings, click devices and printers.

    Click Add a printer. Go through the wizard by selecting the right port (USB 001) and the printer Deskjet 990.

    This should solve the problem for you.

    Not exactly what goes wrong with your installation.

    In general JDeveloper 12.1.3 must be started with JDK 1.7

    You must also have 1.8 JDK on your machine, and the extension of the MAF will need to know its installed location.

    I suggest that you remove the system12.1.3 directory, and then re - install JDeveloper in a new location.

    When you install JDeveloper, if you use the installer of pot, make sure that start you with JDK 1.7.

    (Should be fine if install you using the exe file).

  • Driver problem Audio IDT high definition (HD) after windows 8.1 update 1.

    Hello. I have HP Probook s 4730. After you install the update to Windows 8.1 1 the audio driver has stopped working properly. When I want to play some music or even video system sounds, noise appears after 1-2 minutes. At that time, disk use is 100% cause of isolation of graph for the device windows audio. I installed this driver Audio IDT high definition (HD) on the support site for the driver of HP, but it does not work. As I see it in the device manager driver release date is 24.10.2012. I think it's too old for Windows 8.1. Can you help me? Y at - it another more recent version of this audio driver? Also I send only two pictures where are drive HARD use and driver release date.

    I found a solution to our problem! I installed this driver Windows 7 in compatibility mode. You must remove this one for Windows 8.1 in programs and features, then download this version I have already mentioned, sole extract in a place where you want and install with compatibility mode. To do this, you must enter the configuration properties, then compatibility mode and select Windows 7, also check "Run this program as Administrator". This driver works fine for me. Hope you enjoy it also.
