• HDMI output have suddenly stopped. Pavilion a6340a

  Hello

  I posted here in hope that someone can give me some advice.

  The system in Question is:

  • HP Pavilion a6340a desktop computer. Double heart
  • Vista 32 bit SP2.
  • NVIDIA GF8400GS
  • COMPRO Video mate Vista TV Capture card.
  • 2 GB of RAM.

  It is a bit of an older system, I guess, but it plays well as a HTPC for a while now. It has a small LCD monitor connected via the standard connection and a large flat screen Toshiba TV connected via HDMI. He did a great job.

  Today, the HDMI output just stopped. The Toshiba TV again to survey/is visible in the Nvidia Control Panel and the Vista Control Panel when it is connected to the HDMI. the implementation of the features of multiple monitors are available. But there is nothing happening on TV.

  Things has tried so far.

  • Two different Cables HDMI - nothing.
  • Connected my Pavilion Notebook DV6 on the same HDMI port on the TV - works fine.
  • Installed the latest driver from Nvidia - nothing.
  • Tried all the three HDMI ports on the TV - nothing.
  • Physically, shot the video card in the computer, he dusted off and reassembled it. -Nothing.

  I don't understand. Could this be a processor problem, or I have to pay for a new video card? Is it possible to test the output from the HDMI port with a multimeter or something? I do not understand why it would stop just like that. I just installed Vista SP2 a few weeks ago, but it was working well after I did.

  Any help with this would be greatly appreciated. The system is out of warranty, of course, but it has been a great HTPC for me. I stuck a blu - ray inside player and I was about to give him another 2 GB of RAM.

  Kind of useless now, without HDMI.

  IM at a loss. What else can I do to verify that Exchange of the graphics card?

  Hello

  The short answer is: replace the video card VNvidia GF8400GS. If you happen to have another video card around laying which has an output and HDMI, then install it for a test. It's the fastest way to solve the problem.

• Satellite U400-11U: no sound with HDMI output

  Hi all

  I am the proud owner of a model of satellite U400-11U PSU40E running with Windows Vista.
  Recently, I tried to view a video on my TV. To do this, I used the HDMI output of the laptop connected to the TV.

  I took care to connect the cable to the TV and only after to the laptop.
  Then use the quick access key (Fn + F5), poster image on the TV.
  Unfortunately, there was no noise.

  After some googling, I discovered that I needed to activate the HDMI audio output via the control panel of the sound.
  Unofrtunatly, when viewing, I have found no output Audio HDMI, but only speakers and another exit (whose name I forgot--sorry).

  I tried to update the video and HDMI audio drivers (I noticed that there is a HDMI audio driver in the perpipherals system, which was considered 'work' of Vista), but it changed nothing.

  So, what can I do to activate the audio output over HDMI?

  Hello

  Please see this FAQ from Toshiba:
  http://APS2.toshiba-tro.de/KB0/TSB9401B00001R01.htm

  You will find an instruction how to solve this problem... it s about Qosmio G30 but I think it should work on U400 too...

  The point is that you must set the S/PDIF audio output by default!

  And don t forget to RESTART the laptop after the change was made.

  See you soon

• How to change HDMI output resolution in Windows 7?

  This is a new laptop Sony VAIO Y Series with Windows 7 Professional and a Samsung plasma TV.  Yesterday I connected my laptop and the TV with an HDMI-HDMI cable.  After that I went in Fn + F7 and selected "Projector" only, my desktop screen was successfully mirrored on my TV.   However, after I disconnected and then reconnected the cable, a dialog box appeared and asked me if I wanted to change my resolution of HDMI output.  While I felt fairly certain that my TV supports 720 or 768 only, I chose 1080 p.  (I realized it was a mistake.)  After doing this, the graphics in a video streaming box on MLB. TV is scrambled and very bad.

  So, I think I have to set my resolution of HDMI output for 768 or 720, but I can't determine how to proceed.  I scoured the foundations of knowledge and electronic bulletin boards without result.  I searched through my display settings and resolution.  I have made a restore of the system for the day before my error, also to nothing does not.

  When I right-click on the desktop and select 'Screen Resolution', then select the second (my TV) screen, the resolution drop-down list is 'greyed out', and I'm not able to change the setting, which reflects the 1366 x 768.

  Can someone please?  Thanks in advance for your time.

  Josh

  Hello, Ithilias

  Plug the HDMI and instead choose projector only, choose Extend.

  Now, return to the screen resolution of the screen and you should be able to change the resolution of the display of the second.

• I want to stop Dell Dock d3100 Audio HDMI output.

  I recently bought a d3100 dock and I use it to connect my Inspiron 13z with Windows 8.1 to multiple devices, including an HDMI monitor and stereo speakers.  It turns out that my monitor has built-in speakers and does not allow them to be disabled or cut.  They sound terrible, so I'd like to stop to send the audio signal to them.  Unfortunately, windows detects the Dell dock as a single USB audio device and I don't have the ability to send audio to the stereo output 3.5 mm without sending it also both HDMI outputs.

  If anyone has a suggestion on how to use the HDMI output for video without sending audio to the speakers on my monitor, please let me know.  There are HDMI cables that have an audio connection?

  Thank you, Chris.  It is not a Dell monitor that I'm connected, I use an Acer B273h.  I tried to watch the sounds-> playback settings in Windows.  The problem there is that the d3100 Dell presents itself as a single USB audio device.  There is no distinction between the 3.5 mm stereo output and HDMI audio output.

  However, I found a solution.  I remembered that HDMI and DVI have the same video encoding, and also, my monitor has a DVI input.  So, I picked up an HDMI cable to DVI, which now sends only video to my monitor.

  Problem solved!

• HDMI output in grayscale

  Hello

  I have a Dell XPS 15 computer laptop (L502X) with a Mini Displayport and HDMI output. I'm on WIndows x 64 8.

  I have my laptop in a configuration with 2 external monitors, the two Samsumg Syncmasters (a HDMI, one on DP).

  Recently, the screen that was connected via HDMI shot in grayscale. The image is still correct, only there are no colours (apart from black to white).
  This problem is not related to the screen, because when I connect to laptop to my TV (Panasonic Viera) he has the same problem.

  Any ideas how to solve this problem without offspring of color?

  Thanks in advance,

  Jens

  In the control panel for your video card, use the "reset to defaults" option - which should correct the problem.

• Can we record the SX20 HDMI output?

  We strive to save a training done during a call and I wanted to capture the output HDMI 1 a SX20.

  Is the HDMI output encrypted/encoded to prevent me to do?

  We are considering either acquire an Elgato or Hauppauge game device captures HDMI Passthrough for this.

  Thank you.

  Hello Dereth-

  There would be nothing to keep you from to do this, make sure that the recording device will make audio and video to the monitor.

  One possible option is the 2nd HDMI output, or you are not dual display is to use it to your recording device.  When not to use the SX20 with double displays, it's a mirror of the 1st exit.  One thing to note, and I'm not sure that I have not a SX20 to test, if the 2nd exit send audio conference as the first.  So, you will need to test this as an option.

  The porti is a DisplayPort, not the same thing as an HDMI port.  There is no port HDMI on the T500.  You need an adapter DisplayPort to HDMI.  Look on EBAY or I think you can bea wheat to get one from Lenovo.  The port will give you video but not the audio.

• F5 will not read a map and will not HDMI output

  Hey guys, I'm new here and new to F5. I just got me second hand F5 and opportunity SXS pro + card (64 GB) and the camera is not picking up. When I insert the card, turns bright red media access, and then I get locked out settings. I get a cannot continue message when I try to do something. I don't get a message to format the card, and I don't think I can access the menu to format the card manually because I don't have a HDMI output power on my HD Gratical Zacuto. Any idea of what this could be the cause?

  
  

• Re: Satellite U400-145: no option to select HDMI as HDMI output default

  Hello

  I followed the instructions in the manual its leader to the topic on the HDMI output.
  However, when I go to the sound control panel, there is no digital output device (HDMI) listed only the Conexant Chairman and SPDIF outputs.
  I tried the default SPDIF output, which did not work.
  The HDMI works fine for the image, but the absence of the sound through it is driving me crazy.

  I'm running VISTA (fully updated) on a U400-145

  Someone at - it ideas how I can get the HDMI to appear as an output option?

  Andy

  Hello

  Go to the control panel-> Sound-> playback tab
  There, you have to click to the right.
  Then mark the options; Show all disabled devices
  Then you should see the HDMI interface.
  Now, you could activate and chose as the default value.

• Qosmio G30-161: Cable for HDMI output on DVI input

  I have my G30-161 "HDMI" output as well as the analog out. I began to find a cable to connect it to the DVI to a TFT monitor, but seem to have trouble identifying which is the end "HDMI" cable connection. Does anyone know the formal classification of HDMI connector (or a UK power cable) I can be sure I buy the right cable?

  Thank you very much

• Live streaming and own HDMI output on camcorder SONY consumer (HDR-PJ650VE in my case)

  Hi all

  I'm trying to figure out how I can live streams, using my Camcorder HDR-PJ650VE. I managed to connect the camcorder to my TV by HDMI out and get the live stream, but the problem is that it also displays the superimposed onscreen. It would be a very useful feature, since it this way, you are able to capture the stream by a jury of consumers capture and share it on Youtube for example.

  I cannot find anything on the manual release of the stream HDMI output and get rid of overlapping info. Is there a key combination or a hidden menu to achieve?

  In addition, it seems very strange SONY would not offer such feature, as for example the PANASONIC offers this good enough consumption walked on models like HC-V520

  Please, let me know if it would be possilb esolving this annoying limitation

  Best regards

  Matteo

  I want to share my discovery because it seems to be valid for all SONY camcorders: to have a clean HDMI out, turn off on HDMI CTR.

  I'm very happy now and I'll start live broadcast!

• Not possible to set the HDMI output as default screen on Qosmio G30

  It is not possible to set the HDMI output as default screen! This works only with VGA output. There is no option in the BIOS. According to support, Toshiba will plan any action for this useful feature.

  I use an external TFT with HDMI adapter DVI Cable and I want to have as default screen TFT. With VGA, it will work without problems.
  Any solution?

  Best regards

  Hi Nicolas

  Very interesting question! In my view, HDMI port is to be used with the HD ready LCD TVs or plasma. Combination of connection HDMI and HD DVD movies, you can really have a HD on your TV picture quality.

  As you know the port is a standard VGA port to connect external displays. The image quality is very good and, in my opinion, you should not use HDMI port for the same. Do you perhaps the best image quality?
