HDMI Issue connecting laptop to HDTV

Hi Guys - I had my laptop connected to my HDTV via HDMI. I had unplugged the HDMI to take the laptop on vacation. It's been awhile since I connected it. Now when I connect the HDMI, I am getting the visual but not the audio on the tv. What am I forgetting or do I need to change a setting on the laptop (Toshiba Satellite C855 S5350)?
Thanks!

I believe that you need to go into your audio settings when the laptop is connected to the TV and change the default audio device from the built-in laptop speakers to the entry marked "HD audio" or something similar.
P.S. The cake is a lie.

  • Unable to connect laptop to HDTV

    I have a Compaq 620 laptop and Philips HDTV 42HFL4482F.The OS is Windows 7 Home Basic.The cable Im using is VGA. The laptop screen goes blank and the TV screen reads Video format not supported or no video signal. The Intel graphics media driver  version is 8.15.10.2057 and the accelerator in use is Mobile Intel 4 series Express Chipset family. Also the Intel Graphics and Media control panel says Monitor/TV settings not supported. The key fn +F4 option is of no joy. Can anyone help me please.

    Greetings, 
    After checking the manual of your TV there are a few things I would like to recommend. The first is to ensure that your source is on the VGA setting. You can change this by using the Source button. As well, ensure that you are plugged into the VGA in, and not the RS232 (Service Port).
    If these were both OK, I would reboot your PC after connection and see if you can see a boot screen on your TV. If you can, then more than likely your resolution is set too high. It is important to maintain a resolution of 1920 x 1080 or less. (1920 x 1080 is 1080P/1080i High Definition resolution). Anything larger than this, then your TV will not display your picture, or will display it distorted.
    We need to gather more information about your computer to assist you properly. If you could select the Start menu, then type dxdiag in the search box and press enter. After that has completely loaded, select the Save All button. Save that file to your desktop. Afterwards, on your desktop should be a dxdiag.txt. Open that file and copy from the top to the bottom of the Video section and paste it into this thread.
    Good Luck

  • Issue connecting laptop

    Hi, when I use my phone as a hotspot my laptop cannot pick up the connection but other devices can like my old phone. How can I work around this? I'll be getting an ASDA smart phone at this rate

    I'm having this same problem. Other Android devices work with my Z3C's hotspot, but several laptops don't. They either can't see it at all, or can't connect if even if they can see it. The good news is the USB tethering works great with Windows 7 without having to install any software on your laptop. If you're running some other operating system I'm not sure what your options are. But wireless would be MUCH nicer.
    This is a serious problem. I even did a factory reset and it still doesn't work with the Sony default hotspot settings. i've tried with WiFi on, WiFi off, the power saving disabled, the phone is up to date, etc. I guess it's time to contact Sony.
    Either it's a firmware problem (most likely) or some weird hardware problem. I've fairly sure it's not my provider (T-Mobile) as I can pop the same SIM into a Google Nexus phone and the hotspot works flawlessly with everything.
    Are others here using their Z3C as a hotspot with Windows 7 or Windows 8 laptops?

  • Cannot Connect Pavilion dv6 2020sa laptop to HDTV using HDMI cable

    Hi
    I have tried to connect my laptop to HDTV using HDMI cable but it just comes up with a 'No Signal' message on TV, any ideas?  I have done a search on internet with no joy.
    Operating system is Windows 7
    TV is 32" LG LCD HDTV

    I have been having the same issues trying to connect my Laptop to my TV to use as a DVD player. A normal HDTV cable would not work. I went to Best buy, and found a HDMI cable that said "Laptop to HDMI cable" It was the only HDMI cable out of all of the HDMI that said "Laptop to HDMI". It was also twice the cost, $50.00 for a 10 foot cable. It seems a little to high in price so I am looking for a cheaper one on the web. If I find one, I will post to let you know.

  • Laptop to HDTV Using HDMI and Quicktime

    I'm trying to play a .MOV created by a GE DV1 camera using an HDMI connection from my PC (Dell) laptop to an HDTV.  It doesn't work.  Most of the time it does nothing, sometimes it operates jerkily for a while then quits.  Works fine on the PC monitor.

  • HDMI cable connected from TV to Mac, what do I click on to get the movie on my laptop screen to show on my TV screen?

    HDMI cable connected from TV to Mac, what do I click on to get the movie on my laptop screen to show on my TV screen?

    When you first hook it up it will probably have the display set in Extended Desktop mode. The Menu Bar and Dock will be on the MacBook display and your background screen on the TV but you can move the cursor onto the TV screen.
    In System Preferences>Display on the MacBook screen there should be an Arrangement tab when you have the MacBook hooked up to the TV and both screens working. When you click the Arrangement tab do you see two monitors side by side? One of them will have a Menu Bar at the top. Just click on the Menu Bar and drag it to the second monitor. That will make the second monitor your main screen.
    The TV will now have the Dock and Menu Bar and windows will open on it. But you can move the cursor to the MacBook screen and move windows from the TV over to the MacBook screen.
    You can now use your MacBook in Clamshell Mode with a wired or Bluetooth keyboard and mouse.  http://support.apple.com/kb/HT3131 When you disconnect from the TV your Menu Bar will automatically change back to the MacBook.
    Or if you want to use the MacBook’s keyboard and trackpad to work on the MacBook screen while showing it on a TV you can check the Mirror Display box on the lower left hand side of the Arrangement tab under the two monitors box. That will give you the same screen at the same resolution on both the MacBook and the external monitor.

  • Often lose wireless connection when using HDTV as monitor

    I have an unusual wireless networking problem when using my Samsung HDTV in my living room as a monitor for my MacBook (when watching Internet TV shows, for example). Frequently when I switch URLs, networking freezes, even though the connection appears strong, with the Airport symbol at the top of my screen showing all bars. To re-establish the wireless connection, I have to go through the process of re-joining my network through the “Join Other Network" option. The signal holds as long as I don’t try to change it, as in selecting another URL.
    I connect to my HDTV via HDMI cable, using a mini-DVI to HDMI adapter from my Macbook’s video-out port. The audio connection is a mini-plug from the Mac’s headphone out jack to stereo RCA plugs associated with the TV’s HDMI port.
    The wireless connection is through a Lynksys Wireless-G 2.4 Ghz, 54 Mpbs Broadband router.
    I’d appreciate any solutions the Apple user community has to offer.

    I'd say this has nothing to do with your display. The problem will likely lie in either your router settings, network settings or a simple signal strength issue. Try first changing the broadcast channel on your router, and make sure all settings are correct for your desired network.

  • Help connecting T60 to HDTV

    Hello, I need help to understand what I should do to connect my laptop T60 (1951-bs7) to my Panasonic HDTV (capable to display 1024x768 resolution.
    I just purchased a cable from VGA to component video (Y, Pr, Pb) but when I connect it to HDTV I don't get the video shown on TV, I tried all the resolutions (obviously after doing Fn-PF7 to also have the video signal on the VGA output) I can't get things to work other than a few green dotted lines for the lowest resolution.
    Are there any drivers I should update on my graphic card to allow component to be managed appropriately through VGA ?
    Last but not least, I'm waiting for the T60 advanced dock (I just ordered it), which also has a DVI output: can I expect at least this to work with a connecton DVI-HDMI ?
    Thanks in advance for your help
    Paolo

    you could also try to see if there is an option to configure your laptop for that in Presentation Director.

  • VGA to HDMI issue with Toshiba TV

    Hi,
    I'm having issues connecting an old powerbook G4 running 10.4.11 into a Toshiba TV. I have a DVI to VGA converter from the laptop connected to a VGA to HDMI cable running to the TV's HDMI input. The laptop recognises the television in the display settings but is giving me a blue screen. I've tried restarting, and re plugging in the cables and it just won't work.
    Any advice would be greatly appreciated!
    Thanks

    You need a DVI to HDMI converter or cable. HDMI uses digital video, which is lost when you go to VGA.

  • Sky Go HDMI error from Laptop to TV

    Bought a laptop with Win 8 two weeks ago.Sky Go worked fine on it INCLUDING using HDMI cable to Samsung TV. However, have upgraded laptop to Win 10. Now HDMI insertion stops Sky Go.  Usual errors t 6030 or 6035 with c 4110's.Have tried ALL suggestions on here and elsewhere, but still HDMI connection fails; still works without HDMI cable connected. NOTE that old Windows 7 64bit PC with HDMI output on motherboard STILL works fine using HDMI cable.So WHY does laptop fail to work with Win 10, but worked fine with Win 8? AND old Windows 7 works fine?If Sky in conspiracy with Silverlight are blocking HDMI then they are making a big mistake as the PC/laptop industry are moving to put HDMI on these devices as a permanent output because it carries everything (audio in particular which DVI does not), can carry 4K, and many PC and laptop users now buy TV's as monitors to free up wall and room space, especially in bedrooms. Few if any TV's comes with DVI inputs.Almost all new dedicated PC monitors come with an HDMI input, and users want to use them to enhance modern game visuals.So Sky, is this a temporary Win 10 problem, or are you stupidly blocking outputs that are going to upset and arienate all your FEE PAYING CUSTOMERS?Sky, you must unblock HDMI now, otherwise the negative publicity that users like me will cause will force you to eventually, and I'm going to get Which?  The Consumers Association involved.  We are entitled to use HDMI from PC to PC monitor or TV as monitors. Sky are acting against current hardware trends.There is no licence breach as Sky Go and/or Extra allows 2 or 4 devices.

    It's been a while since I started this thread, and in that time a pattern has emerged. This might assist others. There is a pattern of HDMI problems that occur after ANY update happens. As someone mentioned earlier (thank you) there is also HDCP, that can have sync issues. I have had problems after Windows Updates, Silverlight updates, Windows 10 upgrade and Firefox updates, but they now always go away.  The consistent recovery proceedure seems to be:-Make sure the HDMI cable is NOT plugged into the laptop or PC;-Make sure all instals are done;-Shutdown the laptop/PC completely and remove power, AFTER restarting your laptop/PC after any updates;-Switch off  your TV at the wall, switch off the laptop/PC at the wall and wait 10 seconds (arbitrary number, just to make sure all the transformers are empty of power);-Switch on the power to TV, THEN laptop/PC;-Switch on TV;-Reboot laptop/PC, login and wait for all startup items to run;-Connect HDMI cable to the laptop/PC;-Try SkyGo. If the above fails, remove HDMI cable from laptop/PC, leave laptop/PC on for a while, then try the whole above procedure again.Works for me. Longest I had to wait was 1 hour, so faaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaar.

  • Mid 2010 Macbook pro - Mini DisplayPort to Hdmi issues

    Hi there! I'm having some issues connecting my mid 2010 Macbook pro to my 32" Toshiba LED TV.
    I'm running OS X Version 10.8.2 , as mentioned before, on the mid 2010 Macbook pro.
    The issue which I have, is that when I connect my Hdmi cable to my minidisplay port through the adapter, I keep getting a blue screen popping up.
    I am using a Startech MiniDisplay to HDMI Adapter Converter and ION 6FT Flat HDMI CABLE.
    anyone with suggestions on help?

    I had issues with getting my MBP to work with my Vizio XVT323SV via the RGB port. What worked for me was downloading SwitchResX (http://www.madrau.com/indexSRX4.html) and setting up a custom 1920x1080 resolution using the values found in the Vizio user guide. Works like a champ now. Best shareware investment I ever made. Now I can watch my EyeTV recordings at full HD resolution.
    Hope this helps. Good luck!
    Sidebar: I also bought the Griffin mini-DisplayPort to HDMI adapter and an HDMI cable, but I can't get any signal at all via that connection. The Mac doesn't see the TV and the TV doesn't see a signal. Very frustrating. My RGB connection is good enough but I bet HDMI would be even better.

  • Help w/ connecting MacBook to HDTV

    I want to be able to connect my macbook (black) to my LG HDTV. I am using the DVI adapter to VGA (RGB). All I get is "no signal" on my TV. When I tried it out w/my Dell (didn't need the DVI adapter since my Dell has a VGA input), it worked right away. Anyone know why I would be getting "no signal?"
    Thanks -
    Jen

    I used to have the same problem. I opened up the settings on my laptop while it was connected to my HDTV and under the Display menu I played around with the resolutions. Eventually one of them gave a signal to my HDTV. Hope that works.
