HP ENVY 750se desktop PC: HP ENVY 750se Desktop PC HDMI in Ports

I recently bought a desktop PC HP ENVY 750se who has what I believe to be 2 HDMI in ports which do not seem to work and are not displayed in the "devices" list in the Device Manager. There is also a HDMI port output that works very well.

I was trying to connect a digital SLR camera to the HDMI in ports to capture live streams.

Also, I just checked the details of the product from the order and these HDMI in ports is there are not listed. Yet they are on the PC in an expansion slot.

Help with this is appreciated.

Thank you.

Hi there @ELCF,

I hope you find your experience of positive Support Forum!  I understand that you are looking for help with he HDMI ports on your system.  I'm happy to help you with this.

I suspect that the 2 HDMI ports which you are entered are actually two output ports associated with the onboard graphics, which could be disabled if another dedicated graphics card is installed.  Please see the following documents, in particular one for the motherboard: HP ENVY 750 - 170se computer CTO product specifications and configurable options, HP and Compaq Desktop PCs - specifications of the motherboard, Thimphu.

In the second document, if you look at the section entitled "I/o Ports and riders", you will find the following comment ' 4.HDMI: 2 - not activated when there is a graphics card installed.

Please let me know if explains what you see, and if it does not solve your problem, please mark this message as a solution. Bravo would be appreciated as well.

  • HP ENVY laptop - 14-j153ca: HDMI Audio Driver not installed?

    I am reported a new problem associated with the HDMI port on my laptop HP ENVY - 14-j153ca I bought ~ 6 weeks ago.

    My HDMI provides the video component from my laptop when streaming from a video output on my HDTV (1080 Panasonic 42 "). But last week, the associated audio signal is not be included in the transmission to the audio control on my HD (via HDMI to the TV port). It was working properly before HDTV using the HDMI port, but now is not. HDTV works

    I do not know what sparked the question, but I checked for a driver when studying the sound card details and has not seen a driver for audio support HDMI.

    The computer works normally, and the only software change was the installation of protection software AVG antivirius on 3 February 2016 (expiry the software McAffee test supplied with the machine).

    It would be appreciated if you could help and advise what is required to fix this problem with the lack of HDMI audio during the flow of a video output on my HDTV.

    Thank you.

  • HP Envy 15 1195eo problem of USB Ports!

    I am facing a problem with my usb ports on my HP Envy 15 1195eo. I tried a number of things to make them work, but nothing did. Basically, when I connect a usb device, it will connect, stay tuned for a very few seconds, then disconnect for a few seconds and then connect for a few seconds again, and he repeats like that of infinity. So I'd like prompting assistance works again!

    News of the computer:

    Model: HP Envy 15-1195eo

    OS: Windows 7 64-bit

    Hello again Unboxeremail.

    That solves the problem at the origin?  This can be useful information.

    I took a look inside the laptop and noticed three ports (2 ports standard right) USB and eSATA/USB port a combination on the left, what port is non-functional?  In addition, the image of the motherboard indicates that the USB ports are not on a panel separated from the motherboard so a connection problem is very unlikely here.

    Do you have a multimeter?  Check the USB port to see if the connection is down at random would check it like a hardware problem.

    If the problem persists after a new installation of Windows, then this indicates a hardware problem.  This laptop is guaranteed?  You can see here.  If it is under warranty, you should contact HP support and let them know about the issue. The number for US / Canadian customers is 1-800-474-6836.  If you are in another part of the world, you visit HP's Support around the world to find the coordinates for your region.

  • HP Envy 17-j050US (syncmaster) HDMI questions

    Hello world

    I have this envy 17-j050us Bond in movement and recently when I tried to connect it to the syncmaster via hdmi, I realized this problem.

    I've updated the video driver and sometimes she even recognizes the TV in the "screen resolution" window, but it is still black showing 'no signal' or "cannot do this function" (or something like that)

    I have connected the laptop with another tv and it works. Even with the syncmaster/other devices such as the PS3.

    I couldn't figure it out by myself and its getting on my nerves.

    could someone help me?

    Thank you very much

    Hi again stalonelb,

    Thanks for the quick response!

    Given that you have tested all the components of the environment with your laptop and HDMI connections, and the question rests with the Samsung Syncmaster, I recommend you contact Samsung technical support for assistance.

    I hope this helps!

  • HP Envy X 2 cannot create com port error virtual 577

    Hi all

    Reinstalled Windows 8 32-bit HP ENVY X 2 and updated all drivers (again).

    Try to create the virtual com port with two different Xport and FransonGPSGate programs.

    These programs normally create a virtual Com Port that can be used by e.g. two different programs of maritime navigation at the same time.

    Xport responds: error code error Windows Xport pilot 577 from

    Franson GPSgate responds: unable to create virtual serial ports

    What is the solution for this problem?

    Thanks in advance for your answer!

    Learned a lot the last few weeks on Windows 8.

    I will guide you to acquire the same knowledge for Xport and fully operational Maxsea

    First read: http://www.pcworld.com/article/2027593/windows-8-put-its-hidden-security-features-to-work-.html

    You probably missed it but read what follows:

    "Included in the UEFI is a feature called Secure Boot, which avoids unauthorized operating systems and malicious software from running at startup."

    "Windows, you can type msinfo32 in the start menu search box or invites him to run it to find out the version of the BIOS.

    Within windows 8, I saw:

    -A start secure ACER (old machine): unsupported

    Secure boot disabled in Envy of HP X 2 and

  • 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.
